graduated in Cuba in 1987, with the tile of Doctor in Medicine offered by the University of Havana. He worked as an orthopedic surgeon and dorsal spine until 1993 in the island. After completing all the courses and requirements for the exams of medical licenses in the United States, he was selected in 1997 to complete a year of surgery in the New York Hospital in Queens. He finalized his primary specialty and obtained the Certificate of the Meeting in Physical Medicine and Rehabilitation in the hospital of the University of Nassau in Stony Brook, New York. In 2001, he entered the program of scholarships of the Interventional Pain Management through his specialty in the Florida Spine Institute. Once he finalized this course, he obtained a Certificate of the Meeting in the Management of the pain offered by the American Board of Medical Specialties (American Meeting of Medical Specialties, ABMS).

Actually, the doctor focuses on the investigation of new alternative treatments to the regeneration and restoration of the joint in the Osteoarthritis.

With more than 22 years of medical experience, doctor Castellanos is committed to ensure the best treatment for the pain, including the cellular regeneration medium of Plasma Rich in Platelets and the application of the Mother Cells, so much peripheral, as of the bone marrow, (see on the investigative aspect of the Institute).

Another important facet is the development of the therapy with ozone to treat the pain in which it has worked with brilliant results since 2005, not only in the investigation, but like a pioneer in the clinical application, inside and out of the United States. One of the last contributions is the development of the Spinal Endoscopy to avoid the surgery.

It is important to mention that in spite of his meteoric and brilliant career, the doctor attributes it all to the "grace of God" and that alone he represents an "instrument" to alleviate to those who need it the most. As the doctor says, "I owe it all to him and to Him I respond with my attitude, no coincidences exist, He makes it all possible in a master plan".
