Sports Medicine Clinic

From active kids, to high school and college athletes, weekend warriors, and senior citizens, Dr. Mark Muilenburg and Dr. Philip Van De Griend in our Musculoskeletal and Sports Medicine Clinic are focused on:

  • using ultrasound and ultrasound-guided injections for the evaluation and treatment of acute and chronic injuries
  • diagnosing and treating injuries to the body’s joints, muscles,
    and bones
  • medical problems that arise during sports participation, like exercise-induced asthma and concussions

Our doctors work with our athletic trainers and physical therapists to create exercise programs and rehabilitation plans for rapid return to play. They also work closely with orthopedic physicians and can expedite referral when surgery is required.

Our musculoskeletal and sports medicine clinic also offers non-surgical solutions for repetitive motion injuries like carpal tunnel.

Our team offers the continuum of care needed when you need to get back in the game.
