About Dr. Jerry Hsieh, D.C.

Intero Chiropractic Founder

"My own story started back in 2009 when my wife suffered a massive injury that left her disabled for over half a year. This form of chiropractic is what allowed her to walk again after a dozen failed experiences with doctors. I was so inspired by that experience that I gave up a career on Wall Street and have studied with the best of the best to do the same for others."

Dr. Jerry Hsieh received his doctorate of chiropractic degree from Life Chiropractic College West in Hayward, CA, where he graduated valedictorian and summa cum laude.

His volunteer work ranges from serving world-class athletes at the Ironman Triathlon in Kona and the San Francisco Marathon to volunteer missions in underprivileged communities in El Salvador.

Dr. Hsieh's passion is to educate and support the families of Pleasanton and the greater Tri Valley communities through principled chiropractic care so that babies, children, and adults may live a life of greater health.

From Our Satisfied Patients

After chiropractic care under Dr. Hsieh, my menstrual and back cramps are much less intense and for a shorter duration of time. Chiropractic also helped with my sinus allergies and headaches that have plagued me for years. They're now greatly reduced!


I tell people that Dr. Jerry is a magician. Right after the first adjustment my pain was drastically reduced and each time I came with a sore back, the adjustments have been really helpful


I was born with scoliosis, and I wasn’t sure whether anything could really help with a condition with that I’d had for so many years. After just my first couple of visits, I started to feel relief from my back pain throughout the day.


We Have Helped More than 4,000 Patients

Intero changed my life. Sciatica - gone after one month. I went to them because of persistent lower back problems that I could no longer keep at bay by building my core and stretching. After just one month not only are my symptoms gone but I just feel good. I can stand, sit, and exercise without issues. They use a scientific approach to analyze your condition and tailor the therapy just for you. Plus they really care about their patients. Highly recommended. Life changing for me.
