  • Two of the best parts of my job are being a Firm Lead. The chance to learn, teach, and take care of patients as a team is what first drew me to a career as a clinician-educator. As a Firm Lead, I not only have the privilege of helping support the professional growth of my firm residents, I also get to know the extraordinary, inspiring humans they are outside of medicine. In terms of my personal life, I love being outside – spending time with my family, golfing, and working to improve my novice gardening skills.
