"For more than three years, Dr. Tim has been one of my trusted advisors and medical providers. He’s written some of the most popular articles for the Whole30 and Whole9 websites, has helped me with my own wellness initiatives, and is on my short list of advisors for Whole30-related health questions. If you are looking for an experienced practitioner who treats the whole body (not just symptoms) and truly understands that it starts with food, you need to work with Dr. Tim."
-Melissa Hartwig, New York Times bestselling author, It Starts With Food, co-creator of the Whole30 program

“I’ve been very fortunate to find such an excellent doctor as Dr. Gerstmar. He’s highly educated and very well-read. I’m impressed with how he manages to stay current with latest research and cutting-edge thinking on addressing the root causes rather than just the symptoms of illness. This allows him to handle even the most intricate cases, as well as not be dismissive of patients who have done extensive research on their own, after failing to be helped by the conventional medical approach. Great physicians are analytical problem solvers and true detectives, capable of considering dozens of variables, and multitude of root causes before settling on a course of treatment. Dr. Gerstmar is, undoubtedly, one of them. I would be remiss not to mention his bedside manner – he is a great communicator and listener, treating patients with utmost respect, kindness and compassion. “
