Dr. Dave McCann, D.C. (Clinical Director) is a 1997 honors graduate of Logan College of Chiropractic in St. Louis. His background in engineering prepared him well for his systematic, yet highly creative approach to working with the human body. His extensive study of Applied Kinesiology gives him an excellent knowledge of the muscular system and how it relates to not only the skeleton, but also to the organs and the energy meridians of the body. Through his use of kinesiology, or “muscle testing”, he discovers the hidden causes of dis-ease in his patients.

In addition to being an extraordinary chiropractor, Dr. Dave has a passion for nutrition. His use of the Zyto 5.0 Balance bio-communication device,which measures the body’s positive or negative response to subtle energetic impulses called virtual stimulus items (VSIs). The Zyto Balance and Applied Kinesiology testing, paired with his clinical experience, enables him to find the appropriate nutritional protocol to support virtually any health issue.Dr. Dave’s humor and compassion go far to creating a healing atmosphere for anyone fortunate enough to be on his table.

Dr. Alyson Mather Alyson_Headshot Born and raised in Massachusetts, she received her Bachelors of Kinesiology with honors from the University of Massachusetts at Amherst in 2007. After completing her undergraduate degree, she relocated to Bridgeport, CT to pursue her Doctorate of Chiropractic degree. After graduating in 2011, she decided that she had seen enough snow to last a lifetime and moved to sunny San Diego.

Dr. Alyson developed a passion for chiropractic care while she was still in high school. Her mother had multiple disc injuries in her neck and was suffering from debilitating neck and arm pain as a result. After consulting with several medical doctors who advised her mother that her only options were spinal surgery or lifelong medications, her mother consulted a chiropractor. After one week of care, her mother experienced dramatic improvement. It was then that Dr. Alyson knew that this was what she wanted to do with her life.

Dr. Alyson has experience treating a wide variety of musculoskeletal issues and incorporates various soft tissue techniques, stretching, and exercise into her care in order to achieve the greatest results for her patients. Her mission is to help her patients achieve all of their health and wellness goals, and to foster greater mind-body wellness for everyone.
