Our Physicians
Interventional Pain Management is now recognized as a distinct medical specialty. MAPS physicians are board-certified in anesthesiology, physical medicine and rehabilitation and/or neurology and have additional board certification in pain management. We all work full time in the specialty of pain management. MAPS physicians are specially trained in spinal injection by the American Society of Interventional Pain Physicians (ASIPP) and the International Spinal Injection Society (ISIS) and many are instructors for one or both of these organizations.
