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.

How Can Hyperbaric Oxygen Help with Mold Toxicity?
If you’re like most people, you probably think of mold as that slimy stuff that grows on bread that’s been left out for too long. While it is true that mold can be found in many places – both indoors and outdoors – not all mold is created equal. In fact, some types of mold can be extremely harmful to your health, especially if you’re exposed to high levels of it for an extended period of time.
Common Causes of Bloating and How to Address It
Bloating is no fun. That overly full, distended, even painful feeling after eating can make you pretty miserable and interfere with getting through your days with energy and joy. Many people experience occasional bloating, and for those with digestive conditions like IBS, the vast majority suffer from frequent bloating. You shouldn’t ignore this symptom and just try to live with it.
