Meet the Doctor

Dr. Masi Bayless

Dr. Masi Bayless

Dr. Masi Bayless chose to practice Directional Non-Force Technique (DNFT) Chiropractic because of 3 characteristics important to her in giving back to the community:

1. Safe for all ages and for all types of injuries and chronic pain.
2. Effective at getting people out of pain and back doing what they love.
3. The results last.

Dr. Bayless takes into consideration the whole person and empowers patients to take control of their health with as little professional interference as possible. DNFT is perfect for this: people get well and don’t need to keep returning for more adjustments over a long period of time. She is thrilled to be practicing this technique in Santa Cruz in the footsteps of Dr. Katie Griffin, her long time mentor and friend. Dr. Bayless is also dedicated to staying current on the latest nutritional and exercise research as an avid researcher and biohacker herself she is always trying to find the most natural, efficient way to improve her health along with her patients to give the best results imaginable. She has a special interest in finding underlining causes for chronic pain and inflammation especially fibromyalsia, Ehlers-Danlos Syndrome, as well as mold toxicities that are often unaddressed by standard medicine. Dr. Bayless is a California native raised in Southern California. She majored in biology at University of California in Santa Cruz where she was pre-med. While going through college she worked as a veterinary technician and her love for animals still remains to this day. After college Dr. Bayless worked in the medical device industry for 5 years. Wanting to be more involved with the community and do work she was enthusiastic about, Dr. Bayless decided to pursue her true passion of chiropractic. She attended Life Chiropractic College West in Hayward, CA, where she graduated cum laude in 2015. While in school she took a special interest in sports injuries, McKenzie physical therapy, and, of course, DNFT. Dr. Bayless has always been a sports enthusiast having played volleyball, basketball and badminton in high school. In college, she played Ultimate Frisbee and enjoyed long road cycling trips. Today she lives with her husband in Santa Cruz, CA where they enjoy going on bike rides, hikes and runs with their German Shorthair Pointer “Dash”.

Dr. Katie Griffin is passionate about her work as a Santa Cruz chiropractor and has been committed to providing the holistic care and attention patients need since 1990.   When asked why she cares so much, Dr. Griffin says with a smile, “I just love to help people, whether I help them or refer them to the person who does, I’m confident they will recover quickly and their pain will be gone”. She is a graduate of the University of California Los Angeles with a Bachelor of Science degree in Kinesiology, the study of human motion.
