Born and raised in Ontario, Dr. Diana Nguyen earned her Honours Bachelor of Science in Biochemistry from McMaster University before completing her Doctor of Optometry at the University of Waterloo.

Her clinical training included an externship in Northern British Columbia, where she gained experience in acute eye emergencies, glaucoma, macular degeneration, and diabetic retinopathy. She also co-managed post-cataract and post-PRK surgeries with ophthalmologists.

Additional training in Brampton enhanced her expertise in advanced dry eye disease and glaucoma management, while her University of Waterloo rotation focused on myopia control and specialty contact lens fitting. She practices full-scope optometry with a special interest in dry eyes and myopia control.

Dr. Nguyen welcomes patients of all ages and speaks Vietnamese. Dedicated to continuous learning, she stays up to date with the latest research to provide top-tier patient care. She also serves as an adjunct clinical instructor, mentoring fourth-year optometry students from the University of Waterloo and the Illinois College of Optometry. A respected key opinion leader in the field, she frequently lectures across Canada on various optometry topics.

Beyond her clinical work, Dr. Nguyen is passionate about volunteerism, including participating in a mission trip to Peru. In her free time, she enjoys weightlifting and training in diverse dance styles such as hip-hop, jazz funk, Afro-beats, dancehall, and heels.
