Meet Our Maplegate Team

The organization has evolved both in size and scope of work. They originated as a small three person company with 1,200 square feet and now employ a fifteen person team and occupy over 3,000 square feet. Maplegate Rehab began as a modest medical facility and they are currently a leader in highly skilled rehabilitation services including Chiropractic, Massage, Acupuncture, Physical Rehab, D.O.T., and Physical Exams. They have also recently added MLS® Laser Therapy. 

Throughout their 23 years, Maplegate Rehab has developed a strong track record of providing excellent care to patients. Whether someone is hurt in an auto accident, slip and fall, or a work related injury the main focus is helping them get back to good health.
