Endocrinology Associates of Princeton





Welcome to Advocare Endocrinology Associates of Princeton

Whether performing an ultrasound guided biopsy of a suspicious thyroid nodule or using the latest technology to obtain continuous blood sugar readings to optimize glycemic control, it is our responsibility to stay on top of the latest diagnostic and treatment modalities and we take this responsibility seriously. We are committed to providing evidence-based care to our patients; that is, we base our decision making on the most current medical literature. 

Unlike large, impersonal groups, we strive to be different. We take great pride in being available to our patients and colleagues in the community. We hope that every treatment plan is the product of collaboration between an informed patient and a knowledgeable physician. 

Finally, the work we do is only as good as the effort put forth by our patients; therefore, we insist that every patient is involved in and dedicated to their health.

News & Announcements

If the Ironman World Championships weren't enough, Dr. Hollander put 2 exclamation marks on 2019 in November.  He finished the Princeton Half Marathon in 8th position with a time of 1:20:20 and in 12th position at the annual Trinity Church Turkey Trot with a time of 18:05.  Why not first place?  At 47, Dr. Hollander is more than 20 years older than the handful of athletes that finished in front of him.  Father time will eventually catch us all! Coming off what could have been a career ending injury in April 2019, Dr. Hollander seems to have regained his speed and reminds the medical community that there is simply no fitter endocrinologist in the country and to that point no endocrinologist in the country who understands the intersection between nutrition/ fitness/ and metabolic health while performing at the highest level in endurance sport.  Stay tuned for the release of Dr. Hollander's new fitness platform in January 2021 if you are ready to take control of your health!  
We are proud to announce that Drs. Jason Hollander, Ansu Joy, and Daphne Dadzie were named NJ's 2019 Top Endocrinologists by NJ Monthly Magazine.  Just another reminder why Advocare Endocrinology Associates of Princeton remains one of the most influential and respected endocrine practices in the garden state.

After qualifying for a coveted World Championship slot on his first attempt at the Ironman Distance in Chattanooga TN, Dr. Hollander earned the honor of racing against some of the greatest endurance athletes in the World on Oct 12, 2019 in Kona, Hawaii.  Tired of his place in the Medical Industrial Complex, where medications are the cure for inactivity, obesity, overnutrition, and a litany of related metabolic diseases - Dr. Hollander believes the fundamentals of endurance sport are the right way to battle type 2 diabetes and obesity.  He hopes that in some small way his run through the lava fields of Hawaii last October will inspire his patients to get active and get off the hamster wheel of diabetes medications that is commonplace in modern medicine.  There is no substitute in medicine for good nutrition, good sleep, and regular physical activity... and these are the fundamentals of endurance sport.  
Elizabeth Tursi, APN, CDE is a nurse practioner and certified diabetes educator.  She is dedicated to the care of diabetic patients and is especially skilled in insulin pump management and interpretation of continuous glucose data.  She is collaborating with Dr. Hollander and every care plan will be a product of their combined expertise.  It is truly an honor to have Liz as part of our care team.
