The combined clinical experience of all our doctors equates to over 90 years. Our doctors are also enrolled in ongoing educational certification within the subjects of Integrated Health Care, Functional Medicine, Nutrition and Advanced Chiropractic Technique.

One of the advantages of a multiple doctor office is having access to more than one doctor’s opinion. This equates to more comprehensive and thorough care. Referrals to massage therapists, lifestyle counselors, dietary and medical specialists complete our teamwork approach.
