Gastroenterology Fellowship Fellows

1st Year

BernshteynMichelle Bernshteyn, MD

Hometown: Seaford, NY
Undergrad School: Binghamton University, State University of New York
Medical School: SUNY Upstate Medical University
Residency: SUNY Upstate Medical University
What drew me to Gastroenterology: I knew that I wanted to be a gastroenterologist since middle school. My uncle's diagnosis of stage 4 colorectal cancer inspired my decision to pursue this field to advocate for patients with gastrointestinal disease and moreover, stop cancer in its tracks with a colonoscopy. I hope to ease the worries of patients who are hesitant to undergo this important screening test. This field will allow me to have a hands-on approach to patient care. I am excited to be a part of the Guthrie team as a gastroenterology fellow.
What do I like to do in my free time: Trying out new restaurants, exercising (especially with Pilates classes), spending time with my loved ones, binging great shows, and traveling (my goal is to visit each of the 50 states).

What drew me to Gastroenterology: During my residency, I was impressed by the dedication, supportive nature, and good work life balance of my attendings. I was inspired by the thought process involved in patient care and I learned so much during my rotations in gastroenterology. I was attracted to how using endoscopy, major GI pathologies can be taken care of, saving the patient from open surgical procedures.

Undergrad School: Nova Southeastern University
Medical School: Nova Southeastern University
Residency: Garnet Health Medical Center
What drew me to Gastroenterology: "I fell in love like you would fall asleep; slowly then all at once."" There is no more perfect quote to describe my relationship with gastroenterology. My passion began when I was enrolled in medical school. At that time, I was trying to determine which field of medicine interested me the most and, easily, gastroenterology was my favorite. Over the course of my residency, I had many interesting GI cases that excited me and drove my passion for medicine. I am grateful to be a part of Guthrie's GI fellowship program and hope to take this passion to help as many people as I can! 
What do I like to do in my free time: I really enjoy working out, cooking, traveling, relaxing at home, and definitely enjoy my Netflix binges!

What drew me to Gastroenterology: Gastroenterology is a broad and interesting field within internal medicine. We have the ability to help diagnose and manage a wide variety of conditions that affect the entire digestive system. We are also directly involved in the workup and treatment of our patients through the ability to perform endoscopic procedures. The combination of the breadth of GI and the ability to scope makes for a great specialty!

What drew me to Gastroenterology: Hearing from my patients during my residency and hospitalist job, " when is my bleeding going to stop? " stimulated me to learn a career of doing scopes and take care of problems. It is an amazing opportunity to get knowledge of taking care of complicated GI pathology. It is very rewarding to see when patients recover from not eating at all to eating regular diet.
