Jason Hollander, MD, ECNU

Specialty: Endocrinology

Dr. Hollander was raised in Princeton, N.J. He attended Princeton Day School, followed by Princeton University. He graduated with honors from Princeton University in 1994.

Dr. Hollander earned his M.D. from the University of Medicine and Dentistry of New Jersey. Once again he graduated with honors and was awarded membership to Alpha Omega Alpha (AOA), the highest honor bestowed on a graduating medical student.

Dr. Hollander completed his internship and residency at the Mount Sinai Hospital in New York City. He served as chief resident from 2002-2003, and was recognized as an outstanding teacher in the medical community during that year.

Subsequently, Dr. Hollander completed his fellowship in Endocrinology, Metabolism, and Bone Diseases at the Mount Sinai Hospital. His academic interests included bone metabolism in critical illness, thyroid autoimmunity, and nutrition support in the chronically critically ill.

Dr. Hollander moved back to Princeton after his fellowship with his wife and two daughters, intent on bringing academic endocrinology to suburban New Jersey. To that end, Dr. Hollander was the first endocrinologist in the region to perform ultrasound guided fine needle aspirations of suspicious thyroid nodules. He was the first endocrinologist in the region to routinely identify parathyroid tumors with high resolution ultrasound. He was the first endocrinologist to routinely biopsy malignant lymph nodes…and he was the first endocrinologist in New Jersey to employ the latest gene technology to help his patients avoid unnecessary surgery.

Dr. Hollander has earned the prestigious ECNU certification. ECNU is a professional certification in the field of neck ultrasonography for endocrinologists who perform consultations and diagnostic evaluations for thyroid and parathyroid disorders through both diagnostic ultrasound and ultrasound-guided fine needle aspiration. ECNU is recognized by the American Institute of Ultrasound in Medicine (AIUM), one of the preeminent, national accreditation bodies for ultrasound practices, and allows those with the ECNU credential to be directors of ultrasound laboratories. Moreover, Dr. Hollander personally performs every neck ultrasound – which is unique.

Dr. Hollander is a decorated triathlete and runner, holding several age group titles and having earned the right to compete amongst the best in the world on multiple occasions at the Ironman World Championships in Kona, Hawaii.  He dedicated himself to the sport in 2013 and has had the privilege of working with some of the most respected coaches and athletes in the world with the hope of understanding how endurance sport could heal his patients.  He believes that the cure for type 2 diabetes and obesity will never be found on an operating table, and he is certain that Ozempic and Zepbound are dead wrong for society.  Mental and physical health will always be a product of hard work, education, and proper nutrition. He invites the community to follow him as he trains on @doctorrunning.

Dr. Hollander is available for consultation in our Princeton and Lawrenceville offices.
