This is the difference making medicine she has always dreamed of practicing. Melanie is a great difference maker on the ReGain team. She loves taking the clinical lead as she guides each patient into better health.

For her it is such a positive energy add to see patients transition from being stuck in pain to moving again. That is life restoring.

What is most rewarding for Melanie is the primary impact she can make on the positive health changes for the patients she sees. For her it not just about getting a person back on their feet and feeling better, but more about helping people be their best selves and providing treatments tailored to the individual so that many of them feel better than they ever have. She is all in with the idea of thriving with age and not merely surviving another day. She is a passionate, highly motivated THRIVE MAKER!! If you get to see Melanie, you will enjoy the experience.
