The Institute

The Microendoscopic Spine Institute is driven by a single mission:

We believe that every person suffering from spine problems deserves the highest quality, least invasive, and most evidence-based spine care, and the opportunity to return rapidly to a life without pain or limitations.  We don’t just want you BETTER, we want you BACK.

Arthroscopy has been utilized in knee and shoulder surgery for several decades, but the more challenging anatomy of the spine has prevented the application of these scope procedures to spinal surgery.  The development of microendoscopic spine surgery (spinal surgery performed through a scope and tube) has occurred over the last decade predominantly in East Asia and Europe.

There is a vast amount of scientific evidence for the benefit of microendoscopic spine surgery, with superior patient outcomes, improved patient safety, lower complication rates, and rapid recovery and return to life.

Dr. Simpson currently serves as the Director of Minimally Invasive Spine Surgery in the Department of Orthopaedic Surgery at the Brigham and Women’s Hospital and Harvard Medical School. Dr. Simpson was trained by many of the world’s most talented and internationally recognized spine surgeons.  His philosophy and techniques are a culmination of his experiences with these master spine surgeons. 

Dr. Simpson attended medical school at Yale School of Medicine. He was awarded a National Institute of Health (NIH) Research Fellowship to spend a year conducting numerous clinical and biomechanical spine research studies.

He then went on to surgical residency at the Harvard Combined Orthopaedic Surgery Program, working with spine surgeons at Brigham and Women’s Hospital, Massachusetts General Hospital, and the Beth Israel Deaconess.

Dr. Simpson completed his training with a fellowship at Emory University, regarded as a top fellowship program in the country, before traveling to Japan for further advanced training in microendoscopic spine surgery.

After spending time training internationally in Japan learning microendoscopic spine surgery techniques and seeing how great they were for patients, he wanted to bring these procedures back to the U.S. for his own patients. Dr. Simpson has been performing these procedures for several years, and eventually founded the Microendoscopic Spine Institute, in order to offer these revolutionary procedures to patients on a larger scale.

Message from the Founder

Five years ago I traveled to Japan, and discovered microendoscopic spine surgery, which is spine surgery performed through a small tube and a scope, much like arthroscopic surgery of the knees or shoulders.  These procedures and the technology were remarkable, and it was clear to me that this represented the future of spine care.  My immediate reaction was that this was the kind of spine surgery I would want for myself. 

Since that time, the Microendoscopic Spine Institute has become my passion project.  I want to provide people suffering from spine problems with the very best quality, least invasive, evidence-based procedures to get them out of pain and back to their lives as quickly as possible.

I returned to Japan several times to learn these techniques from the world’s best microendoscopic spine surgeons, and have been performing these procedures for the last several years in the United States, seeing remarkable results with my patients.

The Microendoscopic Spine Institute represents a unilateral, unwavering commitment to patients, and to the philosophy that less is more.  Microendoscopic surgery is not a gimmick, with no “lasers” or false promises.  MSI is simply the most advanced minimally invasive spine technology, supported by high quality medical evidence, performed by the leading spine specialists, giving people the kind of spine procedures that surgeons would want for themselves.
