Our Practice

Portola Valley Chiropractic is dedicated to the holistic health and wellness of each patient. Dr. Hoffman and Dr. Moore have between them over 65 years of chiropractic experience and education. With our highly trained supportive staff of massage therapists, acupuncturists, and an Olympic Gold medal swimmer stretching coach, we can provide you with truly insightful and extraordinary care.

Our doctors use a variety of chiropractic techniques that include Applied Kinesiology, sports chiropractic with kinesiotaping, clinical nutrition, and individualized stretching/strengthening programs that provide a wide range of choices and approaches to your healing process. We also own and use a wide array of physical therapy modalities such as ultrasound, electric muscle stimulation, cold laser, and more specialized equipment like our Foot Levelers Foot Scanner and our newly acquired EWOT machine. At Portola Valley Chiropractic, we treat all ages and all activity levels, and have the means to do so.

"I've never written a review on anyone before, but the quality of Moore's service was so good I wanted friends to know about it in case they ever have problems with their spine or joints.  While my previous chiropractor was very good, Dr. Moore's performance was so much better, he is in a class of his own."

"Dr. Hoffman is a fantastic chiropractor and I highly recommend that you come see her if you are interested in chiropractic."

"Dr. Moore is a great chiropractor! He is very friendly, understands your issues and gets the job done. "

"Great staff! Overall, a friendly and awesome experience. I came here with much hesitation as I really didn't think it would help my back. After a few sessions, I realized what a difference it made. I can't recommend them enough."

"Dr. Moore and Dr. Hoffman have treated me for a few years now and I highly recommend them. They are the most knowledgeable, diagnostic, and friendly chiropractors I have received treatment from and I recommend them frequently to my friends, family, coworkers who express that they are in pain."

"I would definitely recommend this office to anyone seeking a chiropractor for the first time or for anyone in search of a new office to visit. Thank you Dr. Moore & staff!"
