Healthy on paper is not
the same as healthy.
Your labs came back normal. So why do you still feel tired, foggy, and not quite yourself? The truth is that normal simply means nothing has gone wrong enough yet to show up on a standard test, which is a very different thing from actually being well.
THIS IS WHERE THAT CHANGES FOR YOU.

When you finish, you will know exactly where your biology stands across the five systems Dr. Mark and Dr. Michele evaluate with every patient at the Functional Medical Institute, nutrition, movement, sleep, stress, and hydration, scored in plain language with your specific areas of focus clearly identified and a path forward that is built around what you shared, not what the average person looks like.
Why Dr. Mark and Dr. Michele Stand Apart
Dr. Mark and Dr. Michele Sherwood have spent decades asking a question that most physicians never get the time to ask: what is actually causing this, not just what do we call it. Over 25,000 patient conversations later, that question is still the foundation of everything they do at the Functional Medical Institute, and it is the reason their patients get answers that standard medicine rarely delivers.

Your symptoms are the starting point, not the answer
