About Dr. Marc Gruner

Dr. Marc Gruner is a Mayo Clinic–trained sports and regenerative medicine physician who helps active people resolve pain and return to what they love — without rushing toward surgery. He specializes in the prevention and non-operative treatment of musculoskeletal injuries, with particular expertise in diagnostic ultrasound and regenerative medicine.

He earned a joint medical and business degree (DO, MBA) through the Virginia College of Osteopathic Medicine and Virginia Tech, completed his residency in Physical Medicine & Rehabilitation at Georgetown University / National Rehabilitation Hospital in Washington, DC, and pursued advanced fellowship training in Sports Medicine at Mayo Clinic in Rochester, Minnesota. He is triple board certified — in Sports Medicine, Diagnostic Musculoskeletal Ultrasound (RMSK), and Physical Medicine & Rehabilitation.

Dr. Gruner performs minimally invasive, ultrasound-guided procedures — including carpal tunnel release, percutaneous tenotomy (Tenex), tendon scraping, neural releases, and fasciotomy for compartment syndrome — as well as regenerative injections such as PRP, Lipogems (microfragmented fat), bone marrow concentrate (BMAC), and prolotherapy.

Beyond clinical care, he is the Founder and previous Chief Medical Officer of Limber Health, a musculoskeletal digital health platform, and helped pioneer the Remote Therapeutic Monitoring (RTM) CPT codes approved by Medicare in 2022 — work aimed at advancing value-based musculoskeletal care. A native of Bethesda, MD, Dr. Gruner lives in the DC metro area with his wife Rachel and daughter Eva, and enjoys cooking, hiking, and traveling.
