About GrassRoots Functional Medicine

Our Core Values Of Care

A Functional Approach

Rooted in our focus on participatory patient care, it’s our mission to empower individuals with the knowledge, skills, and confidence to live a life that involves physical, emotional, and spiritual well-being.

Guided by our care team, you will embark on a Functional Medicine approach to your wellness, drawing from the best of both natural and conventional practices. We are not interested in temporary solutions that create permanent problems. It is our goal to identify and alleviate the “why” that is driving dysfunction so you can experience long term resolution.


Personalized Care

No patient is exactly the same, and yet there are foundational elements that need to be met to achieve optimal health. Guided by our team, we will get to the root cause of your disease – using diagnostic tests that your current doctor may not even know about.

We’ll explore your situation holistically, uncovering a variety of mediators in your home, at work, and your mental state to arrive at a “lifestyle prescription” that puts you back on the road to health.

Innovative Treatments

Did you know that it takes on average 17 years for clinical breakthroughs to make their way into the standard of care? At GrassRoots Functional Medicine, we are deeply committed to shortening that lag.

We are lifelong learners, continuously upgrading our wisdom through sharing best practices and seeking out innovative, out-of-the-box ideas to help our patients achieve their health goals.

Looking Beyond the Numbers

Your lab results are the “result” of your dietary choices, lifestyle habits, daily routines, body movement practices, sleep schedule, and other environmental factors.
We go beyond treating numbers on a piece of paper. Our objective is to identify what your contributing factors are so that we can partner together to create a personalized, whole health strategy.


Root Cause Resolution

Unlike traditional doctors, our care team always focuses on root cause resolution – isolating the key imbalances that are responsible for virtually all the symptoms you’re experiencing right now.

Also known as Functional Medicine, we seek to give you solutions, not more temporary Band-Aids to cover up the symptoms (or treating side effects of drugs with even more drugs).

Co-Creating Health

Just like your gut bacteria thrive on symbiotic, mutually beneficial relationships, your desired health outcome is much easier to achieve through the power of community.

We leverage group structures for patient education, peer-to-peer support, and accountability – with both your care team and your fellow patients rooting for your success.

The Philosophy That Drives Us

The philosophy that motivates everyone on our care teams at GrassRoots Functional Medicine is pretty simple:

“Do whatever it takes to effectively, comfortably, and safely treat your patient. Whatever that ‘whatever’ is.”

Dr. Osgood founded GrassRoots Functional Medicine on the belief of participatory care where the patient is an instrumental partner in returning their body back to health (or keeping it healthy). And that it’s not about pre-determined ideas about a diagnosis without a full understanding of a patient’s situation.

That’s why the care team at GrassRoots Functional Medicine will leave no stone unturned when it comes to getting to the root cause of your gastrointestinal problems. In fact, the medical community finally realizes that all disease starts in the gut, and without taking the gut into account, no autoimmunity and inflammation processes can’t be addressed at the root cause.

We will integrate findings from the most recent research along with literally decades of knowledge that our team has accumulated. As it is stated in our Core Values of Care, you will always be first in line for innovative, integrative treatment methods that combine the best of Natural and Conventional medicine.

About GrassRoots Functional Medicine

Dr. Osgood discovered early in his career that Functional Medicine was his true passion after a Functional Medicine approach transformed his health, and the health of his family who needlessly struggled for years with digestive problems. Dr. Osgood is an Institute for Functional Medicine Certified Practitioner (IFM-CP) who worked and trained under Functional Medicine expert Dr. Amy Myers. It was at Dr. Myers clinic where Dr. Osgood cared for patients from around the world with complex chronic health conditions, assisting them in their journey to optimal health using a Functional Medicine approach.

Dr. Osgood moved back to New England with is wife and four children to return to his home state of Vermont to spread the reach of Functional Medicine throughout the community where he grew up. He founded GrassRoots Functional Medicine in West Lebanon, New Hampshire and travels back to Austin, Texas on a monthly basis to see patients. Dr. Osgood believes that the current healthcare system has significant discrepancies surrounding the prevention and treatment of chronic illnesses and the future healthcare depends on the actions we take today. It is his belief that the necessary shift in healthcare will stem from a grassroots effort driven by the community demanding root-cause approaches to wellness as opposed to temporary Band-Aids that focus on symptoms. For these reasons and more, Dr. Osgood founded GrassRoots Functional Medicine.

“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.

“Following Dr. Seth’s plan, my hands gradually began to improve. Yesterday I painted my normally-shaped fingernails…”

I went to Dr. Seth with severe eczema on my hands, to the point that some of my fingernails had separated from the skin and were dying and coming off. No one had been able to improve it. On first visit I asked him if he could please make my hands feel better. He said, why don’t we just make them well. Following Dr. Seth’s plan, my hands gradually began to improve. Yesterday I painted my normally-shaped fingernails. And I feel better than I can ever remember feeling! Thank you To Seth! Thank you to Functional Medicine!
