He graduated from Marquette University in Milwaukee, WI, majoring in biomedical engineering with a minor in biology. He went on to earn his MD f rom Drexel University College of Medicine in Philadelphia, Pennsylvania, where he developed an interest in pathology. Having been f ortunate enough to complete an elective rotation in Dermatopathology as a medical student, he decided to work towards sub-specialization in skin pathology. It was the visual nature of pathology combined with the ability to play a role in fighting cancer which attracted Dr. Casey to pathology.

Following the residency match, Dr. Casey moved to New York City to join the anatomic and clinical pathology residency program at NYU Langone Medical Center and Bellevue Hospital. He then accepted a dermatopathology fellowship position at Albert Einstein College of Medicine in the Bronx where he trained at Montefiore Medical Center, Jacobi Hospital, and Dermpath Diagnostics – New York.
