What made you want to become a doctor?  The role called out to me in early high school and I found that I enjoyed the environment of medicine the more I explored it. I particularly appreciated the day-to-day of meeting people of all different backgrounds, being able to build trust, and then trying to have some meaningful impact in their lives in this way that felt unconditional despite who it was walking through the door. I wanted a work/life with diversity that would keep every day interesting too, and the mix of different practice settings like inpatient, clinic, OR certainly does that!

What made you interested in ENT/Otolaryngology? The breadth of practice within a complex, intricate part of the body - there's a true mix of medicine & surgery, short-term vs. long-term patient care, management of acute vs. chronic conditions, and patients of all ages. Meaningful work that impacts the quality of life, the sense that makes life worth living, and sometimes even life itself in cases of life-sustaining care. There's also a lot of scuba correlates.

What made you interested in ENT/Otolaryngology?  There are so many ways in which ENT directly interfaces with what it means to be human, from the most basic life-sustaining needs, to the ability to communicate and interact with the world around us, to the ability to adjust how one presents themselves to the world. The opportunity to provide an intervention that might empower a patient to more fully be able to experience their life, or support a patient through pathologies or injuries that affect these integral parts of one’s identity, appeared to me to be one of the most meaningful and fulfilling things I could do. And I love the collegiality with other disciplines which is integral to each of these endeavors.

Why did you choose the U of MN? The excellent training and mentorship (including in pediatrics), the variety of city & outdoor out-of-work activities, and most of all the culture — almost immediately I found that the residents and staff were as approachable and friendly as they were driven and talented, and I have felt supported not only professionally but for who I am as a person from the interview and on.
