Testimonials From Patients
With diligence and support, following the plan we put together with Dr. Osgood, I’m overjoyed to report my Graves’ Disease is now in full remission!
I wouldn’t have made the progress I have without becoming a patient at GrassRoots and am so happy to be on the path to recovery. In addition to regular appointments, I have access to the whole team for updates, questions, medication changes and other resources, tools and guidance. I no longer feel alone on this journey, GrassRoots is with me supporting me every step of the way.
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.
I’ve gone from barely being able to get through each day to enjoying things that I am passionate about again!
Dr. Osgood took my entire medical history into account – the body, my mental state and support structures, and emotional well-being.
After a year or more of increasing misery and worsening symptoms, I finally began to feel better.
After months of struggling with pediatric Long Covid, Dr. Seth Osgood and the full team of specialists at Grassroots Functional Medicine has transformed my son’s health and continues to show our family that chronic illness need not define one’s life. In my son’s words, “We need to dedicate a building or a tree to this guy!”

Why Choose GrassRoots Functional Medicine?
Too often, people think of “wellness” in temporary terms. They want to work with doctors and take short-term steps to improve their life and “wellness”… but often fall back into their unhealthy routines once their treatment finishes and end up right back where they started.
After years of seeing this happen with patients, Dr. Osgood wanted to open a clinic that not only helped patients reclaim their health and improve their overall wellness, but also give them the tools to continue their progress long after they have left the clinic for good.
