After more than a decade of providing comprehensive, state-of-the-art treatment for pain syndromes, Dr. Robinson in 2012 was acknowledged by Castle Connolly as one of the region’s top physicians. One thing that has become apparent is that pain programs that rely primarily on conventional pharmaceutical medications are limited. For this reason, Dr. Robinson began to search for treatment alternatives that would expand his comprehensive approach and improve clinical outcomes. This approach focuses on optimizing the body’s natural functional and restorative capacity via the tenants of nutrition, hormone optimization and wellness.

In pursuit of the most heavily researched and vetted approaches, he became a Certified Fellow and board-certified by the American Academy of Anti-Aging and Regenerative Medicine. These concepts have served as his inspiration as medical director of Longevity Regenerative Institute. In 2012, Dr. Robinson was also selected into the inaugural class of “Pink Tie Guys” by the Susan G. Komen affiliate in Central and Western Oklahoma to serve as an ambassador for women’s health in the fight against breast cancer.
