Principal Investigator

Mitchell Rothstein, MD


Dr. Mitchell Rothstein is a Clinical Research Investigator at our Fleming Island research site and he has been with us since 2009. In February 2017, we are happy to say that Dr. Rothstein also became our new Phase 1 Medical Director at our Jacksonville University research site. We consider him an all-star at ENCORE Research Group, not only did he perform the first endobronchial stent in Jacksonville, but he also lettered in gymnastics in college. Which is probably why he handles working at two locations with ease.

In his free time, he collects animation art, especially the work of Chuck Jones, the famous Looney Tunes animator. Dr. Rothstein is a major sports fan. He loves watching mixed martial arts and is an Olympics sports addict. He is also a fan of the Jacksonville Jaguars, the New York Mets and the Jacksonville Jumbo Shrimp, our minor-league baseball team in Jacksonville.

While Dr. Rothstein has some downtime, he enjoys eating, he calls himself a ‘happy carnivore’! Some of his favorite TV shows to watch are: Fargo, Billions, Jeopardy, and Snapped. All in all, we’re glad we have Dr. Rothstein as part of our ENCORE Research team and we’re excited to see what he accomplishes with us in the years to come.
