About this clinic

GrassRoots Functional Medicine, a functional-medicine clinic in West Lebanon, specializes in identifying and treating underlying causes of chronic disease rather than managing symptoms alone. The practice focuses on autoimmune conditions, digestive dysfunction, thyroid imbalance, and Lyme disease—presentations that often benefit from systems-based investigation and individualized protocol design. Dr. Seth Osgood leads an evidence-based diagnostic process that typically includes comprehensive laboratory assessment, nutritional evaluation, and lifestyle-medicine interventions. Treatment plans address root drivers such as infection, inflammation, gut dysbiosis, and hormonal dysfunction, sequenced according to each patient's clinical presentation and lab findings. The clinic emphasizes long-term recovery and functional restoration rather than pharmaceutical symptom management alone.

I cannot say enough about my experience with Grassroots Functional Medicine. From the moment I walked in, I felt truly heard and cared for in a way that is rare in healthcare today. The team takes the time to listen, not just to symptoms, but to the whole story—mind, body, and lifestyle. Their approach is thorough, compassionate, and genuinely personalized. What impressed me most is how they combine cutting-edge functional medicine with a grassroots, people-first approach. They don’t just hand out quick fixes—they dig deep to uncover the root causes and provide sustainable solutions that actually restore health. Every recommendation felt intentional and tailored to my unique needs. I’ve noticed real, lasting changes since beginning my care here—not only physically, but in my overall energy, mindset, and hope for long-term wellness. Grassroots isn’t just a practice; it’s a place where healing is made possible through expertise, empathy, and a genuine passion for helping people thrive. If you’re looking for a team that truly partners with you on your health journey, Grassroots Functional Medicine is the place to go. Thank you team!!

As a cancer survivor dealing with long term side effects and staying in the best health possible are both always at play. Grassroots offer more data on how my body was functioning and resources to help it function to the best of its ability. It is an investment, and I was ready to become a participant in my health vs continue to be a patient patient in the health care system. The people at Grassroots are supportive and also invested in my health.

I have struggled with multiple autoimmune diseases since I was a child and have seen many specialists and providers over the last 40 years only making marginal improvements. I had accepted that pain and discomfort was something I had to live with (and I did for many years) until I heard a podcast talking about Functional Medicine. I wondered if maybe this approach would be the ticket to better health. I immediately started researching providers in my area and came across GrassRoots Functional Medicine. I made the call and within a few weeks I was having my first visit with Dr.Osgood. This visit was eye-opening. Dr. Osgood compiled all of the information from my questionnaires and spent over an hour talking with me, getting to know me, understanding my medical history and inquiring about the issues that concerned me most. We made a plan that day...tests and labs were ordered, a visit was scheduled with the Nutritionist and Health Coach and for the first time in my life I felt heard. He wasn't trying to prescribe any medication to help mask my symptoms, he was trying to find out what was causing them. Shortly after my first visit I received a video explaining my test results to watch prior to our next meeting. This video was informative, comprehensive and was a great tool for me to refer to if I had questions or concerns. Dr.Osgood and his team treat you as an individual. If an approach isn't successful he makes adjustments that my body responds better to. There is a holistic approach at GrassRoots. I have learned so much about my diet and how food impacts the inflammation in my body. He understands that with chronic pain and illness also comes stress and anxiety. He and his team are so kind. I have never felt judged for any emotion I have had through this process. The progress I have made in the last 2 years is pretty substantial...imagine if I had started on this journey sooner. I am grateful everyday for this incredible crew of providers for helping to restore my health...both physically and mentally. Take my advice and invest in yourself. Best decision I ever made.
