Chiropractor Caitlin Zimmer D.C.

Chiropractor Pleasant Hill CA Caitlin ZimmerDr. Zimmer loves serving the needs of families through chiropractic. As an avid sports lover, Dr. Zimmer grew up playing water polo, soccer, basketball, tennis, skiing, and swimming.

While achieving her degree from University of California, Berkley, Dr. Zimmer experienced “unexplained musculoskeletal pain” during her water polo workouts. When pain medications and muscle relaxers failed to help her get back into the water, she turned to chiropractic. This experience inspired her to become a Doctor of Chiropractic herself. Dr. Zimmer graduated cum laude from Southern California University of Health Sciences.

Dr. Zimmer specializes in wellness and corrective chiropractic care for infants, children, adults, pregnant women, and seniors. Dr. Zimmer uses many gentle full spine techniques including Gonstead, Activator, Webster, SOT and Diversified.

Completely dedicated to the care of her patients, Dr. Zimmer attends post graduate seminars regularly. Dr. Zimmer is dedicated to serving patients and seeing the miracles daily that occur when the body is allowed to heal itself, with a properly aligned spine and without medication.


Chiropractor Walnut Creek CA Zachary Tannous

Dr. Tannous has a passion for helping people function better through corrective chiropractic care and a healthy lifestyle. As an ex-collegiate Football player for Pitzer University and Premiership Rugby player for Life West, Dr. Tannous uses his athletic experience and his sports medicine background to help many athletes.

At age 17, Dr. Tannous was diagnosed with 2 herniated disks in his low back causing severe pain. He was told that surgery was the only option and to stop playing football. He was introduced chiropractic care by a family member and he started getting adjusted. After a few visits, the shooting back pain was no longer present. He never had surgery and was able to play football.

Dr. Tannous prides himself in giving a very specific adjustment with the use of X-rays to fully understand and address his patient’s needs. He finds joy in helping his patients heal from issues that they believed could not improve and continuing to keep them from ever returning to that debilitating state.

Chiropractic Pleasant Hill CA Dallas CooneyDallas has always lived in the Bay Area, spending most of her life in Concord. She grew up playing multiple sports, with softball being her favorite. She was a softball pitcher for many years. Additionally, she was involved in competitive bowling which has now turned into more of a hobby. In Dallas' free time you can find her spending time outdoors, listening to country music or hanging out with loved ones.

Dallas is very passionate about caring for others and came to us with a long history of Early Childhood Education. Helping people has always been in her nature but now she gets to do so in a medical setting and has the joy of watching patients improve on a daily basis.

At a very young age in life, Dallas was diagnosed with scoliosis (a curve in her spine). It wasn't until she was in her mid-twenties that Dallas joined our team at Zimmer Family Chiropractic and was introduced to Corrective Chiropractic Care as an option to help treat her scoliosis and the overall function of her spine. She is now under care and it has made a huge difference in her life. This experience makes Dallas even more passionate about making sure people of all ages are getting checked in our office and are receiving chiropractic care a lot sooner than she did.
