Why GrassRoots Functional Medicine?

I Am New Here

I Am A Patient

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 “infinitely,” or long after they have left the clinic for good.
