Nithchel Marcelin, PA-C

National Director of Medical Services
With over 18 years as a PA, I have extensive experience in family practice, addiction, and pain management and rehabilitation. Also, I’m experienced in clinical research trials for opioid-induced constipation. I completed my studies in New York City at St John’s University and Touro College. Here in Florida, I am a Florida Academy of PAs and Florida Alcohol & Drug Abuse Association member. While managing the medical services offered by our centers, I am also one of the providers working with the medical director and our other providers to take care of our patients. I collaborate with our therapists to ensure that our patients are taken care of physically and mentally. My goal is to extend this much-needed care to our communities and our veterans as an army officer.

My favorite quote is: “You never know how strong you are until you have no choice but to be strong”.
