Analysis & Treatment of Spine, Nerve & Muscle Damage; Trauma & Disease

​Practicing in Northern Nevada since 1997, Dr. Witmer uses the latest technology to analyze and treat spine, nerve and muscle damage, as well as musculoskeletal trauma and disease. He is trained in electrodiagnostics (EMG), muscle, joint and spine injections.

He uses a team approach to evaluate and treat spine (back and neck) pain, sciatica and pain that is reoccurring or of uncertain origin. Emphasizing time tested, non-operative, minimally invasive protocols for inflammation control, the swelling and therefore the pain, can be mitigated. This control is then maintained with training in a self driven home program of mechanical and medicinal treatments.


Our goal is to create a core of applied knowledge and self expertise of your own condition that helps your care evolve into one of guided self management. Our support will be standing by when needed. Imperative in this is the concept of immediate access when a flare of symptoms begin, so that the path back to normal function and pain control is expedited. We understand and treat from the vantage point that you’re healthiest when active, and this activity can only be reliably pursued with a plan for reining in, and maintaining control of, your pain. We’ll be here for you, especially when the need hits.
