Mary Holdsworth


Dr. Mary Holdsworth was born and raised in Vancouver, BC. After finishing high school, she went to the University of British Columbia to complete a BSc in Biology, Minor in English Literature. In 2017, she moved to Montreal for graduate school and graduated with Masters of Science in Public Health from McGill University. Her graduate research looked at cervical cancer screening in women living with HIV. She then completed medical school at Queen’s University, a tight-knit community where she continued to be involved in student-led initiatives including spearheading a mentorship program for 2SLGBTQ+ medical trainees, founding the Art in Medicine social club, and advocating for her class as Clerkship Representative.

It was during clerkship that Mary found ophthalmology. She loves that this discipline allows her to combine her dual interests in surgical and medical management with her background in public health via its emphasis on function and quality of life. She joined Calgary Ophthalmology in 2023. Her current  projects include the development and validation of a score to detect subclinical keratoconus using epithelial mapping, under the supervision of Dr. Davin Johnson (Queen’s), which she presented at ASCRS in 2023. 


Outside of medicine, Mary’s favourite things include travel, live music, and food. She enjoys being outside and has dabbled in multiple sports including yoga, tennis, hiking, ultimate frisbee, cross country ski, and Taekwondo (in which she has a 3rd degree black belt). She also loves dogs.
