  • Hometown: Redmond, Washington (Russel Wilson has used my parents' dry cleaners!)
  • Medical School: University of Cincinnati College of Medicine
  • Residency Training: Chestnut Hill Hospital Family Practice Residency - Philadelphia, PA
  • Favorite spot in Philly: Hmart!
  • Why Chestnut Hill Family Practice?: The people who make up CHFP. I did not know much of Chestnut Hill Family Practice. Compared to the other big name residency programs I applied to at the time, the program was smaller and less well-known to me. When I visited, however, I felt an overwhelming sense of comfort, safety, and trust. Then I met the faculty and our Program Director, Dr. Marc McKenna. His passion for teaching, caring for people and having fun stuck with me as I made my rank list. I can say that these feelings have not changed; I can be at my best and my worst, but at CHFP I feel safe enough to show those sides of me and know I will be supported and guided to a better me.
