Mike currently resides in Lewiston with his wife Jenn and three daughters and appreciates what Lewiston and the state of Maine have to offer. Hiking, boating, exploring the coast of Maine and outdoor activities occupy most weekends for Mike and his family. “Rediscovery Maine after multiple years living out of state has been an adventure.”
After working multiple years in the construction industry Mike earned a Bachelor of Science degree in Community Health Education from the University of Maine in Farmington in 1995. Mike went on to graduate school to study Physical Therapy at Elon University in North Carolina graduating in 2000.

Mike has been operating Proactive and providing exceptional care to the community in which he lives since 2007. “The sense of community and small town feel of Lewiston is unique and a big part of what we do at Proactive”
Mike's use of current evidence based practice, his experience in the fitness industry and focus on patient education ensures maximum results. Mike stresses the importance of team work between the patient, the physical therapist and the medical community. This team philosophy is paramount at Proactive. “We provided patient centered care at the core. Service based on listening to our patients and individualizing a treatment plan to help you achieve your best.”
Mike’s areas of specialty include treatment of back and neck pain utilizing the McKenzie method of mechanical diagnosis and treatment. The McKenzie approach is the gold standard in treating disc related and mechanical back or neck pain. Use of corrective exercise and hands on techniques to address muscle and joint imbalance in our bodies to restore normal movement patterns is a big part of Mike’s practice. “Educating individuals on how to care for their bodies, self-treat and recovery from injury or surgery is empowering.” Mike has had success helping patients recover from joint replacement surgery, rotator cuff repairs, work related or sports related injuries as well as day to day aches, strains and chronic pain.
