Get to know our staff


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.

Julie Baker

Julie Baker - Registered Nurse and a Clinical Research Coordinator at Jacksonville Center for Clinical Research (JCCR).

My husband was transferred to Jacksonville in 1993, at the same time our CEO Dr. Koren happened to be looking for a research nurse.  We moved from Pensacola, where I had worked for physicians for 10 years.  My favorite part of that job was coordinating clinical research.  So I was excited to have the chance to do research fulltime in Jacksonville.  Little did I know that I had found the best job in Jacksonville!  I was the first person hired fulltime for Dr. Koren’s research team.  It has been a privilege to be a part of the growth of JCCR, doing such important work with such great people! 

I’ve been married to my die hard Cubs fan for 40 years, and we still are each other’s favorite person to be with!  We both love exploring new places, especially our wonderful National Parks.   We are known for planning our travels a year or more in advance! 

After living near the Gulf Coast for 13 years, and in Jacksonville for 24 years, we are spoiled by our fabulous seafood.  We considered moving to the mountains when we retire, but would miss the seafood too much.  So we found our forever house in Jacksonville.  We decided Jacksonville is a great home base, and we can travel anywhere from here.

As a nurse, patient education and safety have always been important to me.  Since JCCR shares the same values, this career has been a terrific fit for me for 24 years.
