Stem Cell Orthopedic Specialist

Meet Dr. Mark Walter M.D.

Over Twenty years ago, Dr. Mark Walter left Ottawa, Canada and migrated to sunny Sarasota. He was in search of warmer climes and the opportunity to practice an advanced, healing-type of regenerative medicine. Today, he is one of Florida’s top Stem Cell Orthopedic Specialists and a pioneer of this speciality in Sarasota. He is excited about the stem cell revolution and how it can  help improve the quality of life for those suffering from orthopedic problems in a safe, minimally invasive fashion that avoids the risks and pitfalls of surgery.

Dr. Walter grew up in Montreal, Canada and in 1980 graduated with Honors from McGill University Medical School, known as the Harvard of the North. His original training was in Family Practice specializing in sports medicine and executive health. For five years he developed and ran a Senior Executive Clinic for Senators, members of parliament, and senior military officers at the National Defense Medical Center in Ottawa, Canada.

Dr. Walter found his calling with Regenerative Orthopedics while doing medical mission work in Honduras with a group of regenerative doctors from the University of Wisconsin. There he learned from, collaborated and taught alongside the best regenerative teachers in the world. Since the year 2000 he has been dedicated to the speciality of regenerative orthopedics and has helped more than 10,000 patients with regenerative injection therapies. For the last decade he has integrated regenerative injection methodologies from Prolotherapy with leading-edge stem cell technology and this has enabled him to achieve an impressive 85 percent success rate with such common problems as knee and hip arthritis, back pain, rotator cuff, sports injuries, and many other serious joint problems – without surgery and with minimal downtime.

Dr. Walter has recently published his new book STEM CELL ORTHOPEDICS: A Primer on Regenerative Orthopedics

As a stem cell specialist, Dr. Walter is a leading proponent of “the art of regenerating joints” and the key importance of addressing the connective tissue “pain generators” as well as the cartilage, disc and bone component. As a clinician he is highly skilled at using the palpation interrogation technique (a term he coins in his book) to identify the critical structures that are causing pain and injecting them with safety and precision. Since 2012, Dr. Walter’s seminal work has been to develop advanced stem cell regenerative injection protocols that integrate the knowledge and efficiency of Prolotherapy injection methodology with the latest stem cell technology.
Dr. Walter is dedicated to excellence in the field of Regenerative Orthopedics and Stem cell therapy. He founded ProloMD in 2002 which has evolved into RegenOrtho: Stem Cell Specialists and has considered it a privilege to serve and contribute to the quality of life for residents of Sarasota and Southwest Florida for the last 24 years.
