    Leading in motion sparing spinal surgery. Dr. Graham Mouw is a board certified Neurosurgeon. A nationally recognized leader in motion preservation spinal surgery and spinal restoration, he has pioneered techniques in order to restore the spine to a more natural state in order to relieve pain and suffering. Most surgeons emphasize spinal “fusion” where bones are fused together creating a rigid state without the natural motion of the spine. Dr. Mouw is able to utilize the newest technologies, many of which he has pioneered, to restore the spine to a more natural state with full motion.

    Dr. Derek Dee uses the latest minimally invasive technical procedures, some of which he developed on his own. Combined with the right biologics to allow early return to high-level sports and recreational activities is what Dr. Dee focuses on. There are challenges to delivering what is optimal to the patient in today's healthcare climate. Although not contracted with some insurances, we accept most as out-of-network providers; our goal is to do what is in the best interest of the patient, as opposed to what insurances will allow. My staff and I will do all we can to provide quality care, but to treat you as people - people with jobs to return to, kids to pick up, sports to get on with, and mountains to climb. The strongest pain killer I know is doing something you love - we have the expertise to get you back out there, whether you are a professional athlete or weekend warrior. LIVE BOLDLY.
