Pathology

Hometown: Anasco, Puerto Rico
Undergrad School: University of Puerto Rico, Mayaguez Campus, Mayaguez, Puerto Rico
Medical School: Ross University School of Medicine, Barbados
Hobbies: I recently began knitting while I studied for the Step 2 CK exam. It was a way for me to unwind between study sessions and I was very proud of my first creation, a beautiful blanket. Gardening is a hobby I had before medical school and haven’t been able to continue due to moving constantly for rotations. Whenever I go back home to Puerto Rico I usually plant fruits trees and germinate seeds. Hopefully I can get back to gardening during residency.
