The one thing that is very clear about COVID-19 is that certain populations are at high risk for serious disease related morbidity and mortality.  Diabetics are among those at highest risk.  During this pandemic, we are determined to keep our doors open (at least our virtual doors) to provide care to thousands of diabetic patients in the region.   Moreover, we are proud to be open and able to accept new CONSULTATIONS via Televisit.  


We have been experiencing remarkably high call volume during the COVID19 pandemic.  Your call and your health is important to us.  We strongly encourage that all non-urgent issues including medication refills, simple questions for your doctor, even requesting an appointment be handled via out secure patient portal.  This will unload the phones and improve your experience with our practice.  If you find a longer than desired phone wait time and matter cannot be handled via the portal, please consider calling back in the afternoon.  Our morning call volume tends to be the highest - this is particularly true on Monday mornings.  Thank you, Dr. Hollander

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.
