Envisioning a future as a family medicine physician, I sought out to choose the program that would best prepare me for taking care of any patient who walks through my door. Interviewing with Hackensack Mountainside, I not only witnessed the strong culture of academic excellence and community involvement, but also the sense of camaraderie and support between the attending physicians, residents, and staff. When I matched to Hackensack Mountainside, I was thrilled to learn that I would be able to complete my training at a great program close to home.

One of the first things that drew me to the Mountainside Family Medicine program was the diversity of education the residents received. I loved that the program placed emphasis on residents being educated in the clinic, the hospital, the emergency room, nursing homes, the delivery room, the OR, inpatient floors, and much more. After meeting everyone at the program, I feel confident that I will develop the skills to have a positive impact as a Family Medicine physician, and that I would be supported by both the faculty and my co-residents.

I selected HackensackUMC Mountainside because North Jersey is my home and Family Medicine is my passion. I wanted my residency training to be done at a community hospital that has deep roots in North Jersey while having the support of a large health network such as Hackensack. What stood out to me the most was how friendly and approachable everyone was from the attendings to the residents. I feel reassured that I will be trained to become a confident, knowledgeable, and compassionate physician who will continue to serve the healthcare needs of North Jersey residents for years to come.

Pursuing a residency in Family Medicine allows me to give back to the community that has provided me with so much.  Growing up in the area, I have encountered a diverse group of people, culture, and experiences that shaped me into the person I am today.  As such, there was no doubt that this was where I wanted to train and eventually serve as a physician.   Choosing Hackensack UMC Mountainside Family Medicine Residency program as the provenance of my professional training was the best decision that I have made.

Although I interviewed virtually, I, and anyone for that matter, could feel the family energy exuded by HackensackUMC Mountainside FM Residency Program. When looking at residencies, many factors come into play. For me, I was hoping to join a residency that will provide excellent education, has fantastic mentorship, and that was close to home. The Mountainside FM residency Program has all those qualities and more. This can clearly be seen through the past and current residents. It was a joy discussing how residency was for them and for them to wholeheartedly recommend coming here.

Having rotated at Mountainside Family Medicine as a medical student, I saw how tight knit the residents, faculty, and staff members were. The camaraderie amongst the residents, the vast knowledge of the attendings, and the helpfulness of staff really drew me in. Since the first day of residency, I felt immensely supported by everyone in the program and am grateful to call this place my home for the next three years.
