“I am lucky enough to work in the best field of medicine and I now have the honor to help train the next generation of psychiatrists. I want to use the skills and knowledge that my mentors gave me to usher in the next step in the growth of St Luke’s Psychiatry. What I hope most is that when our graduates leave, they will leave carrying on the mission of St. Luke’s University Health Network to provide the best psychiatric care in the region and become passionate physicians who continue to find joy in the art of medicine.”
