I have been battling ME/CFS and autoimmune disease for 5 years. I lost all of my energy and enthusiasm. Most days I was consumed with “brain fog” and chronic systemic inflammation that prevented me from having enough energy or focus to work. I sought help from countless doctors without resolution. I was so relieved to find Dr. Osgood! He has multiple certifications within the field of functional medicine. He took my entire medical history into account and considers the body, mind and spirit as a whole. His unique approach to treatment is exemplified by the utmost thoroughness, compassion, and enthusiasm! Dr. Osgood solved the mystery of my complex illness by uncovering the root causes behind my diseases. His treatment plan has me well on the path toward healing. This will be the first year in several that I can resume my passion - hiking in the mountains! I am so grateful for his care!read more

Testimonials From Patients

“Dr. Seth has helped me reverse my autoimmune disease and I am now feeling better and better after each visit!…”

When I started seeing Dr. Seth I was lost, desperate and miserable physically and emotionally. I had spent over a year seeing multiple doctors and specialists, none of which could figure out what was wrong with me or help me. Dr. Seth has helped me reverse my autoimmune disease and I am now feeling better and better after each visit! Healing the gut and getting my body to a healthy state has taken time but it has all been worth and I could not have done it without Dr. Seth’s expertise and direction!

“That all changed after seeing Dr. Osgood. Functional medicine SAVED my life…”

After almost a decade of chronic illness, pain and autoimmune issues that should have been under control given my constant care under specialists and physicians alike, nothing ever resolved nor helped and my quality of life was extremely poor. That all changed after seeing Dr. Osgood. Functional medicine SAVED my life.
