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. If you’re looking for a team that truly partners with you on your health journey, Grassroots Functional Medicine is the place to go

Your labs came back “normal.”
You don’t feel normal.
Most people who book this call have already done the right things: the specialists, the prescriptions, the diets. What they haven’t had is someone looking at the whole picture at once.
You’ve seen three or more doctors and still don’t have a clear answer
Your prescription list keeps growing, but you don’t feel better
You’re told it’s stress, age, or “in your head”
Fatigue, brain fog, gut trouble or pain is shrinking your life
You want to fix the cause, not manage symptoms forever

Meet our Founder
Dr. Seth Osgood, DNP,
FNP-BC, IFM-CP
Founder of GrassRoots Functional Medicine and host of the GrassRoots podcast, practising root-cause medicine since 2014.Dr. Seth Osgood is the founder and clinical lead of GrassRoots Functional Medicine in West Lebanon, NH. A board-certified Family Nurse Practitioner with a Doctorate in Nursing Practice and certification through the Institute for Functional Medicine, his clinical work focuses on root-cause resolution of metabolic, hormonal, and gut-driven dysfunction. He treats patients in-person across the Upper Valley and via telehealth across NH, VT, NY, FL, and TX.
“"I built this clinic because I was the patient conventional medicine almost lost.”
Patient stories
“I finally began to feel better.”
“All of the staff at Grassroots has been amazing. 9 months ago I could barely walk through the door. My health and mental health were rock bottom. Today I’m feeling like a new person. I’ve worked hard and followed all of the recommendations, not always easy! I have more energy, I’ve lost 35lbs, I eat healthily and walk 4-5 miles a day plus engage in other outside activities. I’m amazed at how much my mental health has improved and my outlook has changed from bleak and depressed to positive.”
“I've worked with Seth and his team for many years now. I've had their support and encouragement through good times and some very tough times. Dr. Osgood is attentive, responsive, really listens, and recommends care and modification that is a real contribution to my health and wellness. Everyone at Seth's office knows that there's not a one size fits all approach to health care. I'm grateful for the personal attention to my health including making me aware of new research and approaches.”
“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.”

Common Questions
Something else on your mind? Call or text 888-644-7668, Monday–Thursday, 8am–5pm ET
Is the call really free?
Yes. No card is needed to book, and there’s no obligation to go further.
Is this a sales call?
It’s a fit conversation. We’ll tell you what we’d recommend and what it costs. If we’re not the right fit, we’ll say so and point you toward a better next step.
Who will I speak with?
A member of our patient care team, not a call centre. They speak with people in your situation every day, they’ll have read your intake answers before you talk, and they work alongside Dr. Osgood and our clinicians, so they can tell you plainly whether your case is one we can help with and what that would involve.
Do I need to live near New Hampshire?
No. We see patients in person at our West Lebanon, NH clinic, and we care for patients virtually across New Hampshire, Vermont, New York, Florida and Texas.
If you’re outside those states, book anyway and tell us where you are. We’ll be straight with you on the call about what we can and can’t do from a distance, and point you toward a sensible next step either way.
Do I need recent lab work?
No. Bring whatever you have. If you haven’t been tested, we’ll talk about where to start.
What if I need to reschedule?
Use the link in your confirmation email, or call or text us. Please give us 24 hours’ notice so someone else can have the slot.
