Dr. E. Quinn Regan is a board-certified orthopedic surgeon who specializes in treating cervical and lumbar degenerative disease such as spinal tumors, spinal stenosis, herniated disks, sciatica and cervical radiculopathy.

Taking advantage of advances in the field that have produced treatments unavailable even ten years ago, Dr. Regan offers patients the latest treatments, including minimally invasive surgery. Dr. Regan originally studied engineering in college, but discovered he wanted a career that would help people directly. Spinal surgery allows him to apply his engineering background to the treatment of the human body.

He has suffered from back pain himself for 25 years. He brings to his patients a compassion for their conditions based on his own experience. His goal as a physician is to enable each of his patients to function at their highest level possible relative to their condition.

Dr. Regan is an assistant clinical professor of orthopedic surgery at the University of Illinois College of Medicine. He is conducting research that seeks to decrease rates of infection from spinal surgery.

I think of myself as a coach to my patients, keeping them functioning when a spinal ailment arises. You have to deal with the psychological aspect of the patient, the physical aspect of the patient, and the age of the patient to maximize what is the best solution to their medical problem."
