Our List of Orange County’s 5 Largest Employers

If you Google “Orange County”, the first results will probably describe the region’s list of attractions and outdoor activities. All this is true. However, it only paints half the picture. Today, Orange County has a thriving business environment with a lot to offer. Here, you will find some of the world’s largest companies. They come to Orange County to enjoy the thriving business environment and work with a pool of talent that helps them grow further.

We love OC businesses and therefore took it upon ourselves to create a list of the 5 largest employers in Orange County. So read on for the official My OC Bookkeeper list of the OC’s largest job creators.

The Walt Disney Company

Topping Orange County’s largest employers list, The Walt Disney Company with about 30,000 employees countywide. That is why, it plays a vital role in the Orange County economy. The Walt Disney Company operates in four business segments: Media Networks, Parks, Experiences and Products, Studio Entertainment, and Direct-To-Consumer (DTC) and International. That is why, it always offers a steady stream of diversified job opportunities.

At The Walt Disney Company, they understand how each member of their staff will have an impact on people’s lives worldwide. That is why, they don’t hire just anybody. (Interesting fact: they may have hired the mother of one of our staff members.) They also ensure that their staff comes from unusually diverse demographic backgrounds – the company is 52% female and 43% minorities.

From the start, The Walt Disney Company has branded itself as the place of making dreams come true. That is not just their mission with their customers. The Walt Disney Company also tries to help its employees reach their dreams. That is why, they invest in their employees’ education through their Disney Aspire program. For all these reasons and more, The Walt Disney Company is not just the largest employer in Orange County – it also has a great employee retention rate, with staff members usually staying with the company for 3.7 years.

(Sidebar, do yourself a favor and watch the video below. It’s about Disney’s longest standing employee who worked there for 65 years! We’re not sure what his thoughts on the 5 largest employers in Orange County are, but we suspect he likes at least one of the companies on our list.)

University of California

The second largest employers in Orange County are not from the private sector. With 23,884 employers, UCI tops the list as the largest public sector employers in Orange County. They are also contributing $7 billion annually to the local economy and $8 billion statewide.

Over the past few years, UCI has been growing rapidly in many areas. That is why, its size of employees has also increased drastically. Founded in 1965, UCI is considered the youngest member of the prestigious Association of American Universities. It also ranks among the nation’s top 10 public universities by U.S. News and World Report. With three Nobel laureates, UCI is known for its academic achievement, cutting edge research, innovation and its infamous anteater mascot. That is why, Forbes has named it one of the best employers in the USA.

County of Orange

Offering about 17,271 jobs, the County of Orange lands in the third place of our list of largest employers in Orange County. The County of Orange is a local governmental agency responsible for developing, managing and providing a wide range of public services. Their scope of services includes public safety, public health, environmental protection, regional planning, and social services. To deliver all these services in a responsive and timely manner, the County of Orange partners with regional businesses and other governmental entities.

At the County of Orange, the staff comes from unusually diverse demographic backgrounds. The organization is 53.5% female and 54.4% ethnic minorities. This diversification is also extended to the political orientation of the employees, with 49.7% Democrats and 46.6% Republicans. The County of Orange also offers good working conditions, health, dental, medical insurances, paid time off, 401k plan, etc. That is why, their employee retention rate is high with staff members usually staying for 6.6 years within the company. No wonder the County of Orange has ranked number 4 on the Best Government Companies to Work for in Santa Ana, CA list.

St. Joseph Health

When you think about the largest employers in Orange County, usually big names, such as Disney or Boeing, come to mind. That is why, many people get surprised when they see St. Joseph Health in the list. With a workforce of 14,000 employees, St. Joseph Health lands on the well-deserved fourth place in our list.

This Catholic not-for-profit, health care system has long and storied roots in Orange County. Its first hospital in Orange County, St. Joseph in Orange, was founded in 1929. Today, St. Joseph Health includes 16 hospitals, physician organizations, home health agencies, hospice care, outpatient services and community outreach services. They cover California, Texas and New Mexico. In 2016 and 2017, St. Joseph Health was awarded Top Workplaces Regional Awards by the Orange County register.

Kaiser Permanente

As one of the nation’s largest not-for-profit health plans, it is no surprise that Kaiser Permanente lands in our largest Orange County employers’ list. With a workforce of 8,178 jobs, Kaiser Permanente serves 12.5 million members.

For over 76 years, Kaiser Permanente has been leading the way with innovative approaches to health care. Their goal has always been to deliver high-quality and affordable health care services. Kaiser Permanente Orange County hospitals are among the best in the nation for delivering high-quality care, according to the U.S. News and World Report’s 2021-2022 “Best Hospitals” rankings. They have also been recognized on Glassdoor’s 2019 Best Places to Work list.

Our List of the 5 Coolest Tech Firms in Irvine

Orange County has always been synonymous with sunny, beach towns. However, today cities like Irvine have a lot more to offer. That is why, over the past years, more and more tech firms and start-ups have been gravitating to the area.

Today, Irvine is considered one of the leading cities in the tech scene. It is known for hosting the offices of huge tech firms as well as rising start-ups. All these cool tech companies come to Irvine to have access to the talents they need to grow. What better place to find these talents other than Irvine?

For years, UC Irvine and other institutions have been known to graduate a deeply educated workforce. That has been Irvine’s Master Plan since decades ago; to be a city of intellect, built around the university. Obviously, Irvine is going on the right track. Today, you will find the offices of some of best tech firms in the world here in Irvine. Here is our list of the 5 coolest tech firms in Irvine.


Should we say more? Most probably, you have reached this article using Google search engine. As they say, Google knows everything. That is why, Google has dominated the search engine market, with about 92.5 percent. However, that did not stop Google from expanding their success to other services. Today, thousands of users around the globe enjoy Google mail services, productivity tools, enterprise products, mobile devices and much more.

This tech giant is not just famous for its revolutionary product launches and innovative approach. Google is also known for its extraordinary work environment and employee facilities. Google Irvine office is no different. Designed by San Francisco-based Rapt Studio, Google Irvine building catches Orange County’s beach culture. You will find beach cruisers in the lobby. There is even a lifeguard tower on the roof deck.

Workspace design might not be enough to get Google on top of our coolest tech firms in Irvine. However, Google commitment to expanding opportunities and building a diverse workforce is. That is why, Google has claimed the 6th spot in Glassdoor’s 13th annual “Employees’ Choice Awards, with a rating of 4.5, in the best places to work in the 2021 list.


Over the past decade, many people thought Microsoft has lost a bit of their shine. However, they have made a strong comeback. Today, Microsoft has become again one of the superstar firms not just in Irvine, but in the entire tech world.

By introducing Windows 95 back in the days, Microsoft has ushered the world into the golden age of PC usage. Computers were no longer just meant to be used at work. People bought PCs for their homes. That is when Microsoft became a dominant player in the tech scene.

The period from the mid-2000s up to 2014 was a dark phase for Microsoft. The company could not compete with Google in the search engine field. They also had a little success with smartphone operating systems or devices. Still, companies and regular users did not stop buying Windows computers. Fortunately, Microsoft decided to build on its strength to come back stronger than ever. They returned to their roots by introducing the game changing cloud computing technology, which is considered one of the most important technologies of the past decade. This and the cultural change landed Microsoft on our coolest tech firms in Irvine.


Unlike Google and Microsoft, Syntiant is headquartered in Irvine. Founded in 2017, this tech firm has quickly become a leader in the moving artificial intelligence and machine learning technology. Syntiant produces ultra-low-power semiconductors that facilitate speech interfaces on various battery-powered consumer devices.

In simpler words, Syntiant offers a breakthrough technology that enables small devices, such as earbuds, to offer voice interaction. This means, you can give your smart speakers, AR glasses and security devices command words to control them. No need for bulky batteries or control buttons, your tiny, battery-operated devices will execute your commands just by using your voice. How cool and brilliant is that?

Compared to traditional processing technologies, Syntiant devices typically deliver 100 times the performance. That is why Syntiant was named one of the top 100 AI companies. Syntiant’s exceptional work was also recognized by Octane, Southern California’s leading accelerator. In 2021, Syntiant received their High-Tech Award for “Best Technology Company Leadership Team”. The work of Syntiant is also backed by multiple of the world’s most well-known investors including Intel Capital, Applied Ventures, Robert Bosch Venture Capital, Microsoft’s M12, Amazon Alexa Fund and Atlantic Bridge Capital.


Also based in Irvine, is Cylance Inc., a medium-sized software firm that develops antivirus programs. Unlike other cyber security firms, Cylance software works proactively. It prevents, rather than reactively detecting viruses and malware. To prevent cyber breaches and attacks, Cylance uses artificial intelligence, algorithmic science and machine learning technology. They are considered the first tech company to apply this advanced technology to cyber security. Clients of Cylance include companies in industries such as retail, finance, healthcare, government and education in Irvine and across the USA.

Cylance was founded only in 2012. Being a relatively young company did not stop Cylance from becoming a leader in the cyber security world. Their CylancePROTECT software is an award-winning next-generation antivirus product. It can stop what other antiviruses cannot even detect by using prediction and pre-response at the enterprise endpoint. That is how, CylancePROTECT can effectively prevent modern malware and advanced threat breaches, before they can cause any damages or harm. That is why Cylance’s Fortune 500 customer list includes hot shots such as 20 of the biggest energy, oil and gas companies, 34 of the best healthcare companies, 43 of the top banking and financial services companies and 46 of the top high-tech companies.

The 5 Best Businesses in Irvine

Our List of the Best Businesses in Irvine, CA

What are the best companies in Irvine, CA? That is not an easy question to answer. Irvine is the beating heart of Orange County business. (Sorry Newport Beach, you’re great too but there can only be one…) What used to be basically a sea of orange groves with a university in the middle – not to say there is anything wrong with that, old Irvine was a wonderful place – has turned into an incredibly dynamic and crucially important business hub.

So, determining the best businesses is not an easy feat. We like challenges though, so we think that we are up to the task.

This is not a scientific endeavor, so we don’t have a great deal of empirical data to discuss. Rather, we have sought out companies that are provocative, successful, and / or have had an impact on the community.

So, without further ado, the best businesses in Irvine.

Space X

First on our list is Space X. Why is it first? Because it is Space X, that’s why. I mean, they are trying to go to mars people, and they have an office in Irvine. (That basically means that the good people of Irvine will be part of the first Martian colony.)

Elon Musk’s company, whose home office is in nearby Hawthorne, by the way, opened its offices in Irvine back in 2016. The office’s apparent focus is satellite communications, which seems important to us. They’ve been here ever since, with many a job opening on Indeed to prove it.

What could be more exciting than having a developer of cutting-edge space technology in your backyard? Nothing, that is what. And that is why Space X is on our list.

Looking for a job at Space X? First of all, thank you for being incredible. Second, check out this blog post with tips on getting a job at Space X. (It’s not ours.) Third, please leave a note in the comments, we would love to chat.

Last point, be sure to check out the awesome video below to see a Space X spaceship landing vertically. Incredible. If you watch just one video in this post, that should be the one, trust us. It’s really cool.

Ingram Micro

Unlike Space X, Ingram Micro is headquartered in Irvine.(Space X just has offices there.) Formed all the way back in 1979 – in Southern California no less – Ingram Micro is a massive organization with ~ 35,000 employees, $49.1 billion in revenues, and over $15 billion in assets. They distribute IT products and services to over 250,000 customers both in the U.S. and around the globe, and are one of the biggest names in their industry.

According to our research they are regularly hiring all kinds of positions in Irvine, so if you are interested in information technology and are local you should keep them on your radar. That having been said, if you aren’t looking for a job in IT don’t fret, Ingram Micro is a publicly traded company (NYSE: ticker IM), so if you have a few dollars squirreled away you can literally join the ownership team. Sidenote, if you do become an owner, please tell them to reach out to us for their outsourced finance department needs.

Want to learn a little bit more about Ingram Micro? Take a look at their video introduction below.

The Hoag Health Network

Next on our list is the Hoag Health Network. This is truly a local company in every way because all of their operations are right here in Orange County. (Maybe you should think about doing that too Space X and Ingram Micro.) Not only that, but they work hard every day to keep all of us healthy, and we here at the My OC Bookkeeper blog are very grateful for that. Strictly speaking they are a non-profit but given the incredible work they do and the number of OC residents they employ we decided to include them anyway.

The incredible Hoag network treats roughly 30,000 inpatients and 350,000 outpatients annually. They opened way back in 1952 (when Orange County was actually filled with oranges), with Hoag Health Center Irvine opening in the early 80s, and Hoag Hospital Irvine opening in 2010. They are here to help us all with medical needs large and small, and we are certainly grateful for that. Thank you Hoag Health!

Interested in volunteering with the Hoag Network? Here’s a good place to start.

What to learn more about how Hoag has grown over the years? Take a look at the video below which has some really great historical footage from old Orange County.

Blizzard Entertainment

No list of the top businesses in Irvine would be complete without Blizzard Entertainment. Blizzard is one of the top video game companies in the world, having created such well known titles as the World of Warcraft, Diablo, StarCraft, and Overwatch – all of which have many iterations.

The company was founded back in 1991 by three UCLA grads, and its headquarters are right here in Irvine. Not only do they create incredible video games, but they also employ roughly 4,700 people. As if that wasn’t enough, they also sponsor the annual BlizzCon convention which draws gaming fans from across the county to our own Anaheim Convention Center – providing yet another boost to local business.

Thank you for the great games Blizzard, but please don’t make them so addictive. We need time to get some other things done.

Want to see an awesome video about Blizzard’s games? Take a look below.

The Irvine Company

What is the last company on our list? It should be obvious. It’s inconceivable not to include the company with Irvine in its name on the list of the best companies in Irvine, the queen bee of all companies in Irvine: The Irvine Company.

For those of you who don’t know. The Irvine Company is a real estate development company with offices in Irvine and Newport Beach that has played a major role in the development of not just Irvine, but large swaths of Orange County. They own The Market Place, the Irvine Spectrum Center, and Fashion Island, and have helped develop countless residential areas throughout the county.

It’s not just their great development projects that make them great though, it’s also both their commitment to protecting Orange County’s natural environment and their philanthropic endeavors. From an environmental standpoint, they’ve earmarked nearly 50,000 acres as preserved wildlife – known as the Irvine Ranch Open Space – which helps to preserve Irvine’s great balance between nature and development. From a philanthropic standpoint, they’ve gifted over $220 million to local schools and universities.

The 5 Best Parks in Irvine

Our List of the Best Parks in Irvine, CA

Everyone in Orange County knows that Irvine is a great place to live, do business, or both. It’s one of the safest communities in the country (that’s the entire country), it’s home to the great University of California, Irvine, and its got a long list of great amenities – including all kinds of great parks. As fans of our blog likely know, we love parks, and just published a list of the best parks in Mission Viejo. (That’s where our home office is.) We had so much fun doing that we decided to follow it up with a list of the best parks in Irvine, CA. So, if you are a fan of parks, or Irvine, or just reading random things on the internet, strap yourself in and get ready for the definitive guide of the best parks in Irvine.

The Heritage Community Park

If you spend a lot of time in Irvine and you’ve never been to the Heritage Community Park then you’ve got some explaining to do. This is a crown jewel of a park. The list of amenities is literally too long to offer you here but includes 3 pools, 1 amphitheater, 3 basketball courts, 20 picnic tables, 22 BBQs (that’s 22 folks), 12 tennis courts, 2 children’s play areas, 2 racquetball courts, 3 soccer fields, 2 concession stands, electrical outlets, and oh yes, a lake, to name a few.

Throwing a party? You can also reserve the kitchen, lounge, craft room, picnic shelter, or gazebo at the Heritage Park Community Center which lives there as well. In fact, if you want to do so, just click here.

Believe it or not, the city of Irvine is actually in the process of trying to improve the park further and developing a new ‘master plan’. If you really want to drink deeply of this great park, you can get involved in the ongoing planning process – details available here.

Colonel Bill Barber Marine Corps Memorial Park

The Bill Barber Marine Corps Memorial Park is another shining example of park-hood that resides in Irvine. This greenspace is named after Colonel Bill Barber who received the medal of honor for bravery for his actions in the Korean War and passed away in Irvine in 2002. (To learn more about the late great Colonel Barber take a look at his biography on the Congressional Medal of Honor Society Website here.)

Clocking in at approximately 42 acres, this is quite a large park. There is no shortage of amenities either, which include soccer fields, tennis courts, baseball diamonds, batting cages, access to two local bike trails, restrooms, BBQs, multiple gardens, and an amphitheater, among others. The gardens, amphitheater, and picnic shelters are available for reservation, and you can find information on doing so here.

There’s literally nothing not to like about this park, so we hope to see you there next weekend.

Click below to see an interesting video about Colonel Barber’s heroics. Thank you so much sir. We are forever in your debt.

William R. Mason Regional Park

If you thought that the Colonel Barber Marine Corps Memorial Park was big you will be blown away by the William R. Mason Regional Park which spans a whopping 339 acres. In addition to BBQs, playgrounds, picnic areas, ball fields, volleyball fields and horseshoe pits, it offers well regarded hiking, biking and equestrian trails and a 123 acre ‘wilderness area’. Oh, and it also has a lake which is renowned for the omnipresent population of model boats.

This park represents the perfect combination of hiking activities and park activities and we plan to be there soon – hopefully you’ll be there to.

Mike Ward Community Park

The next park on our list is the Mike Ward Community Park. While not quite as expansive as the other parks on this list, (it’s a mere 22 acres) this is a great spot to get some quiet downtime to unwind. The park boasts BBQs, picnic tables, basketball courts, a volleyball court, an amphitheater, and a lake – it is in Irvine, after all. One of the unique things about this park is that it doesn’t have any playgrounds, so if you are looking for a place to relax away from the kids for a while – this might just be the place for you.

It’s also known for its summer concert series, where you can enjoy a long list of great concerts every summer. Be sure to check out the City of Irvine website before heading out for one of these though, as some require tickets.

One of the Best Park System in the Country

The final park on our list isn’t even a park, it’s a ranking. The parks in Irvine are so great that they have been ranked as one of the top ten systems in the country on multiple occasions by the Trust for Public Land. Each year the Trust creates an index ranking the best park systems in the country based on variables including access, investment, amenities, acreage, and as of 2021, equity. Irvine scored 6th in 2019, and 7th in 2021. (They’ve probably ranked on other occasions as well but we can’t spend our entire day researching this article.) You can learn more about Irvine’s award in 2019 here, and their award in 2021 here.

There you have it, our favorite parks in Irvine, CA. You literally can’t go wrong with any of the parks on this list, and we hope that you find time to try out each and every one.
