Peggy Cherng: The Engineer Who Helped Turn Panda Express Into a Restaurant Empire

Before Panda Express became one of America’s most recognizable fast-casual restaurant brands, Peggy Cherng was an engineer and computer scientist with a Ph.D. in electrical engineering. Her transition from designing computer systems to building one of the world’s largest Chinese-American restaurant businesses might seem unconventional, but it reveals the systems-driven thinking behind Panda’s remarkable growth.

Together with her husband, Andrew Cherng, Peggy helped transform the family’s restaurant business into Panda Restaurant Group, applying technology, operational discipline, employee development, and a relentless focus on consistency to an industry traditionally driven by intuition and experience.

Key Takeaways

Technical skills can create unexpected advantages. Peggy Cherng used her background in engineering, computer science, and systems design to build more efficient restaurant operations.
Scaling requires systems. Panda Express grew from a single location into a major restaurant business by developing processes for inventory, sales, customer feedback, training, and operations.
Consistency can be a competitive advantage. Delivering a reliable customer experience across thousands of locations requires the same kind of discipline found in successful technology and engineering organizations.
People are as important as technology. Panda’s investment in employee training and internal career development helped create the talent infrastructure needed to support long-term growth.
Entrepreneurs should leverage their entire background. Cherng’s story demonstrates that skills developed in one career can become powerful competitive advantages when applied to an entirely different industry.

From Burma to the United States

Peggy Tsiang Cherng was born in 1947 in Mawlamyine, then part of British Burma, to Chinese parents. Her early life took her through China and Hong Kong before she eventually moved to the United States for college.

Her academic path was anything but ordinary.

She earned a bachelor’s degree in applied mathematics from Oregon State University before completing a master’s degree in computer science and a Ph.D. in electrical engineering at the University of Missouri.

Her doctoral work involved computer analysis of chest radiographs, placing her at the intersection of engineering, computer science, algorithms, and pattern recognition.

Those technical skills would later become surprisingly important to the growth of Panda Express.

From Engineering to Restaurants

After completing her Ph.D., Cherng pursued a conventional engineering career.

She worked at McDonnell Douglas, where she was involved in system design and coding battlefield simulators for the U.S. Air Force and Navy. She later worked at Comtal Corporation, a 3M subsidiary, where she became involved in software development, image recognition, and eventually management of a software department.

But while building her engineering career, Cherng was also helping with another business.

Her husband, Andrew Cherng, had established Panda Inn, a Chinese restaurant in Pasadena, California. Peggy began helping with the restaurant during nights and weekends.

The experience eventually changed the direction of her career. By the early 1980s, Cherng decided to leave engineering and devote herself to the family business.

It was a significant career change. But rather than abandoning her technical background, she brought it with her.

The Engineer Behind Panda Express

In 1983, Peggy and Andrew Cherng opened the first Panda Express location at Glendale Galleria in California. The concept was relatively simple: take the flavors and dishes associated with Panda Inn and adapt them into a faster, more accessible format suitable for a shopping mall environment.

But scaling a restaurant concept is considerably more difficult than opening a successful single location. The Cherngs needed consistency.

Food needed to taste the same across locations. Inventory needed to be managed efficiently. Employees needed to be trained. Customer feedback needed to be captured. Restaurants needed to understand what was selling and what was not.

This is where Peggy’s engineering mindset became a competitive advantage.

She helped develop computer systems for inventory management, reordering, customer feedback, sales analysis, and point-of-sale operations. Instead of treating technology as something separate from the restaurant business, she used it to create a more systematic operating model.

That philosophy would become one of Panda Express’s most important advantages.

Turning Restaurant Operations Into a System

Restaurants are notoriously difficult businesses to scale. A great chef can make one restaurant successful. A charismatic owner can build a loyal local following. But replicating that experience across hundreds or thousands of locations requires systems.

Cherng understood this early. Her approach was essentially to turn Panda Express into an operating system for restaurants.

Processes could be measured. Inventory could be tracked. Customer feedback could be analyzed. Employees could be trained according to consistent standards. Managers could be developed internally.

Technology could help management make decisions based on data rather than intuition alone.

That approach allowed Panda Express to preserve consistency while expanding rapidly.

The lesson is particularly relevant to entrepreneurs outside the restaurant industry.

Scaling is not simply about doing more. It is about building systems that allow more to be done without losing quality.

Building Through People

Technology was only one part of Cherng’s philosophy. She has also placed considerable emphasis on people development.

Panda became known for its internal training programs, including the company’s “University of Panda,” as well as a strong promote-from-within culture.

The philosophy is straightforward: Instead of constantly searching outside the organization for managers and executives, develop people who already understand the company’s culture and operating principles.

This creates institutional knowledge. Employees understand the business because they have experienced it from the ground up. It can also create a powerful incentive for employees to stay and build their careers within the organization.

For a company with tens of thousands of employees, that kind of organizational infrastructure can be just as important as technology.

From One Location to a Restaurant Empire

The results have been extraordinary. Panda Restaurant Group has grown from a family restaurant operation into one of the largest privately held restaurant businesses in the United States.

Panda Express has expanded to roughly 2,600 locations, generating billions of dollars in annual sales and employing tens of thousands of people. The company has also remained largely company-owned rather than pursuing the aggressive franchising model common in the restaurant industry.

That decision gives Panda greater control over operations, training, customer experience, and brand standards. It also reflects the Cherngs’ broader philosophy: maintain control over the systems that make the business work.

What Entrepreneurs Can Learn From Peggy Cherng

1. Your Previous Career Can Become a Competitive Advantage

Cherng did not throw away her engineering career when she entered the restaurant business. She repurposed it.

Her knowledge of software, systems, data, and process design became valuable precisely because the restaurant industry was not traditionally dominated by engineers. Entrepreneurs should therefore think carefully before dismissing experiences from previous careers as irrelevant.

Sometimes the skill that seems unrelated to the new business becomes the company’s most unusual advantage.

2. Build Systems Before You Need Them

A company with five employees can survive through informal communication; a company with thousands cannot.

Cherng’s emphasis on technology and standardized processes helped Panda develop the infrastructure required for large-scale growth.

The lesson is simple: founders should begin documenting and systematizing important processes before growth makes them impossible to manage.

3. Consistency Is a Form of Innovation

Innovation does not always mean inventing something completely new. Sometimes innovation means finding a better way to deliver the same experience repeatedly.

Panda Express succeeded partly because customers knew what to expect. That consistency is difficult to achieve across thousands of locations.

Cherng’s operational philosophy turned consistency itself into a competitive advantage.

4. Invest in People as Aggressively as Technology

Technology can improve efficiency, but people determine whether an organization can execute. Panda’s investment in training and internal advancement helped create a pipeline of employees who understood the company’s culture and operating model.

For entrepreneurs, the lesson is particularly important during periods of rapid growth: Hiring people is not enough; companies need to develop them.

The Importance of Staying Private

Another distinctive element of Panda’s story is its ownership structure. Unlike many restaurant chains that have pursued aggressive franchising or public-market expansion, Panda has remained privately held and largely company-owned.

That gives the Cherngs significant control over long-term decisions.

It also allows the company to focus on its own operating philosophy rather than quarterly expectations from public-market investors. For entrepreneurs, this raises an important question:

What kind of ownership structure gives your company the best chance of achieving your long-term goals?

Going public is not automatically the definition of entrepreneurial success. For some businesses, independence may be more valuable.

Beyond the Restaurant Business

Cherng’s influence extends beyond Panda Express. Through Panda Cares and the Cherng Family Trust, the family has committed substantial resources to healthcare, education, children’s causes, medical research, and community development.

The Cherngs have supported institutions including Caltech and City of Hope, among others.

This philanthropic work reflects another dimension of the entrepreneurial journey: the opportunity to use business success to create impact beyond the company itself.

Cherng has also served on prominent institutional boards, including the California Institute of Technology’s Board of Trustees.

The Bigger Lesson From Peggy Cherng

Peggy Cherng’s story challenges the conventional image of the entrepreneur.

She was not a typical restaurant founder. She was an engineer and computer scientist who entered the family restaurant business and applied a technical mindset to an industry built around food, hospitality, and human interaction.

That combination proved powerful.

Panda Express was not built simply by finding popular recipes. It was built by creating systems capable of delivering those recipes consistently at enormous scale.

Cherng understood that technology, data, training, and operational discipline could turn a restaurant concept into a repeatable business model.

That may ultimately be her most important lesson for entrepreneurs.

A great business is not simply a great idea. It is a system capable of delivering that idea repeatedly, efficiently, and at scale.

Peggy Cherng brought engineering into the restaurant business. In doing so, she helped build a company that demonstrates how seemingly unrelated disciplines can come together to create an enduring competitive advantage.
