Brad Sisson MD

Chief Executive Officer / Medical Director

Dr. Brad Sisson is a highly experienced physician with over 30 years of clinical practice in anesthesiology with a fellowship in pain management and regenerative medicine. He completed his residency in Anesthesia and Critical Care at the University of Chicago and his fellowship at the prestigious Northwestern Memorial Hospital. Dr. Sisson is double board-certified and brings deep expertise in regenerative medicine, pain management, physical medicine and rehabilitation, health and fitness, and functional medicine. As Medical Director at Colorado Accident & Injury, Dr. Sisson leads a dedicated team with a mission to provide comprehensive, patient-centered care for individuals recovering from auto accidents, sports injuries, and other musculoskeletal or neurological trauma. His extensive background in return-to-function medicine makes him particularly effective in diagnosing injuries often missed at the emergency room or urgent care and then designing personalized treatment plans for each patient. Under Dr. Sisson’s leadership, Colorado Accident & Injury offers a thorough and proactive approach to diagnosing and treating injuries—often identifying issues overlooked by busy urgent care clinics and emergency departments, which primarily focus on triage and ruling out life-threatening conditions. Unlike traditional practices that are often bound by insurance limitations and time constraints, Colorado Accident & Injury is purpose-built to give patients the time and attention they need. Our providers perform in-depth evaluations, including detailed histories, physical exams, and appropriate diagnostics. We specialize in treating concussions, soft tissue trauma, spinal injuries, and other complex conditions. Our care protocols align with Colorado Workers’ Compensation guidelines, offering aggressive diagnostic work up followed by conservative, evidence-based treatment strategies. Dr. Sisson and his team are proud to offer a unique model of care—focused, flexible, and committed to helping each patient return to optimal health.
