Where Eastern & Western Medicine Meet

East West Medical Group has been serving the greater Orange County area for nearly 30 years. The integration of Eastern and Western medicine is at the core of our philosophy. We combine healing techniques that have been around for thousands of years with the latest in modern medical science.

Our diverse team of experienced medical professionals are dedicated to providing the highest quality of health and wellness care to each and every person. Our focus is on finding and addressing the root cause of illness, rather than treating the symptoms alone.

We offer acupuncture, chiropractic medicine, internal medicine, massage therapy, and herbal/nutritional counseling as part of our holistic approach to healthcare. We also have an in-house herbal pharmacy that offers a wide selection of herbal supplements for sale. Our medical services are provided in a welcoming environment that is filled with light and open space to enhance a sense of wellness and promote healing.

We accept Medicare, most PPO insurances, and some HMO plans. A current list of accepted plans can be found here.  However, if you are a new patient please contact your insurance provider or give us a call prior to visiting to verify your coverage.

History & Mission

In 1989, Dr. Stephen Tsai and his wife Mimi had a vision to start a clinic for integrative medicine. They decided to open East West Medical Group in Fullerton, believing it was God's will to do so. The clinic started as a 600 square foot office with only Mimi to manage the office and Dr. Tsai to treat the patients. Through word of mouth and referrals the business grew, and eventually other doctors began coming to the clinic to learn about, and ultimately incorporating, integrative medicine into their own practices. Together, the Mission Statement of East West Medical Group was created:

"To offer high quality healthcare by integrating Eastern and Western medical techniques and philosophy, and to create a comprehensive care plan for every patient that focuses on the healing of mind, body, and spirit."

Dr. Tsai has since seen tens of thousands of patients over his nearly 30 years of practice and currently serves as a member of the Board of Directors for the St. Jude Memorial Foundation. His unique approach of combining Western medical knowledge and Eastern holistic medical philosophy has allowed him to become well-known throughout the community, with many traveling from outside of the Orange County area to seek his care.

 

In 2008, the clinic was moved to it's current location: a 10,000 square foot facility located near the heart of Downtown Fullerton. The clinic has grown into a multidisciplinary primary care center, and today employs a comprehensive team of medical doctors, chiropractors, and staff who all share the same vision of holistic and integrated health care.
