Our Doctors

Amy Lennon, DC

It really never gets old. I love what I do so it’s fun to keep studying it & searching for new techniques. I have acquired many ‘tools’ for my doc bag and continue to learn when it is best to use them. I am grateful for the notable, trustworthy & wonderful referral base that my patients can access, from surgeons to art therapists. I work daily alongside massage therapists, acupuncturists, and physical therapists in order to apply the most comprehensive care for you. The way I provide care is holistic, from soft tissue assessment & nutrition to the way you move and what your specific goals are; I am open to hearing what you need, be it complicated or just a quick treatment. I am thorough so I can be confident & then I can be as specific as possible with my care. My patients continue to bring incredible meaning and so much love to my life; I am so thankful.

He tends to be a very gentle provider and is the “brains” of the family, graduating magna cum laude from Chiropractic College. 
He also played Ultimate Frisbee for over 20 years, winning the national championship 2 times as a member of the Santa Barbara Condors. He was voted into the Ultimate Frisbee Hall of Fame in 2011. Now he enjoys traveling with his family, running, and day-to-day family life.

Arden Freedman, DC

Arden received his BS from Cornell University and his Doctor of Chiropractic from the University of Western States. Growing up, he was a devoted soccer player, which led to a history of injuries. Through the utilization of chiropractic, he was able to continue playing competitive soccer throughout his undergraduate studies. This led him to join the world of  chiropractic care. He strives to help people live more enriched lives and has found his passion in helping eliminate the barriers that stop people from doing what they love. Just like his chiropractor was able to help him continue his passion of playing soccer and staying active!

Through personal experience, Arden has gravitated to an integrative approach to care with an emphasis on adjusting and muscle work, as well as targeted exercises that get to the root of the problem. He believes that his job is not only to help people heal, but to also give them the necessary tools and knowledge they need to empower themselves into feeling even better than they did pre-injury. Arden has a strong interest in understanding the cause of an injury, which has led him to study human biomechanics. This interest has led him through training by the Prague School of Rehabilitation in the principles of Dynamic Neuromuscular Stabilization as well as becoming a certified yoga instructor. He has also completed training in the McKenzie Method of Mechanical Diagnosis and Therapy, which is especially efficient at treating disc herniations.
