I work with clients virtually via phone or Zoom. If you prefer to meet in person, I have limited office hours at my Beacon Hill Boston office.

(more) I consider myself “integrative” which blends my traditional medical nutrition training with my more holistic and functional medicine based training. I have also been an intimate part of a chiropractic practice (my husband is a chiropractor) and have educated myself on other modalities as well such as Acupuncture, Reiki, and Aromatherapy.  Most of my clients already have a medical doctor so YES, I often recommend “alternative” (I prefer complementary) treatments/practitioners to enhance what they are already doing. My job is to EDUCATE and therefore empower and inspire my clients to seek optimal health through whatever modalities works for them.
