Get to Know Dr. Barrie Weinstein

Why Did You Become a Doctor?

I am the first doctor in my extended family. Growing up, my father  struggled with his ulcerative colitis.  He was so grateful to his many physicians who provided personalized care and ultimately helped him avoid surgery. As such, the impact and value of high quality, long-term, personalized care was clear to me from a young age. I have been fascinated with the medical field for as long as I can remember and love the relationships I build with patients while developing the right care regimens for them.

What Made You Focus on Endocrinology?

In medical school and residency, I found Endocrinology fascinating because it encompasses so many different organ systems. I loved the puzzle of figuring out the key underlying issues and viewing the patient as a full person rather than one particular system of organs. Endocrinology offers the opportunity to get to know patients very well, understand their challenges, assess the relevant empirical evidence, explain available treatments, and find the right plan for each patient. Working with patients to find the right solution for them and then seeing the results is exciting for me, every time. The mix of patients, challenges, treatment plans, and preventative care regimens means some patients come in for just a few visits and others develop years-long relationships.

What Is Your Approach to Medicine?

Listening to patients’ needs, wants, and medical history and applying my two decades of expertise is how I provide the best personalized care. I spent 18 years at The Mount Sinai Hospital, an academic institution, so my practice is based on an evidence-based approach. Additionally, medicine is ever-evolving, and I have found that there is a time and place for alternative treatments, supplements, and approaches that may not yet have the randomized control study to back them up. Providing the highest level of care takes time. At Mount Sinai I saw up to 25 patients per day, meaning less time for each patient. One of the reasons I joined Well by Messer was because I wanted to have more time with each patient in order to more fully understand their history and needs and assess the right plan for them.

How Would You Define Patient Care?

Patient care is all about developing a deep understanding of what a patient needs and applying the proper treatment course to address their concerns. It involves being respectful and responsive as well as collaborative with their other providers.

Do You Do Any Philanthropic Work?

I dedicate a portion of my practice to patients from underserved communities and do not charge them any fees.
