About Us
Experience Matters
RBI is the premier provider of high quality regenerative biologics including stem cell therapy and platelet rich plasma (or PRP) to patients throughout the Treasure Coast and Florida. The RBI team has been developing advanced cell processing techniques and treatment protocols for nearly 15 years. We have been involved in the treatment of thousands of patients worldwide. Our goal is to treat the underlying causes of diseases and tissue damage for patients instead of just treating their symptoms. We do this by harnessing a patient’s own incredible healing capacity, concentrating it and then injecting it directly into an area of need such as an injured or arthritic joint.
Regenerative Medicine Expertise
RBI's team is unique in that we have both experienced stem cell scientists and clinicians who have worked in all facets of the field of regenerative medicine including stem cell therapy, platelet rich plasma therapy, gene therapy, tissue engineering, specialized cell delivery systems and more. Our team has also been involved in major stem cell clinical studies at leading institutions throughout the U.S. and the world including the Mayo Clinic, Cleveland Clinic, Scripps Research Institute, Mount Sinai, the University of Florida, Columbia University, Duke University, Minneapolis Heart Institute and more.
