DR. LAURA THOMAS

Dr. Laura Thomas, a Hamilton native, graduated from the University of Waterloo Optometry program in 1994 on the Dean’s Honours List, after working on her undergraduate degree of Honours Biology and Psychology at the University of Guelph and McMaster University.

She became a partner in the practice in 2007 and completed her therapeutic drug training in 2009. Dr. Thomas really enjoys the challenges that a full scope optometry practice provides and appreciates the relationships she develops with her patients. She has a special interest in children’s vision and sees kids referred in by family physicians, pediatricians and other patients from across the city. She feels privileged to provide eye care to the Dundas/Hamilton community and she works very hard to keep up to date with new treatments and technologies as they develop. When not wearing her “eye doctor” cap, Dr. Thomas enjoys spending time with her husband, two active children, and friends. She enjoys downhill skiing, running, hiking, kayaking, canoeing and camping.


DR. KATIE MANN

Dr. Katie Mann joined Dundas Optometry as an Associate in 2009 and was thrilled to become a partner in 2015. Born and raised in West Hamilton, she was a patient here at Dundas Optometry, where Dr. Johnson became her mentor.

During her final year of studies, she completed internships here at Dundas Optometry, Image Optometry in Vancouver, and the Utah Eye Institute in Salt Lake City. Upon graduation, Dr. Mann traveled with a classmate to Ghana to volunteer with Unite for Sight, an NGO committed to providing eye care to remote communities in the developing world. For the first few years of her career, she split her time between Dundas Optometry and Spadina Optometry in downtown Toronto, and as of 2015 she is at Dundas Optometry full-time. She lives in Burlington with her husband and two sons and when she's not at work, she enjoys travelling, skiing, and spending time with her family at their Muskoka cottage.

DR. BETTY JOHNSON, retired December 2022

Dr. Johnson opened Dundas Optometry Clinic in the fall of 1989, and the rest is history. She has been a pillar at the practice for many years and although her colleagues and patients will miss her, her retirement is well-deserved.

"I thank each and every one of you for putting your trust in me. It has been a privilege and an honour to have been providing optometric care to you and your family. I leave knowing that every doctor and staff at Dundas Optometry Clinic will continue to serve this community's visual needs for many years to come at the highest standards that you have come to expect from us." - Betty
