Felicity has been a part of the Dundas Optometry family since 2013 and in June 2016 she successfully completed her courses to become a Certified Optometric Assistant. As one of our receptionists, she is one of the first smiling faces you will see when you come in our front door. She always makes our patients feel welcome and well taken care of. An expert multi-tasker, Felicity keeps things running smoothly at our front desk, which is essential in a busy clinic like ours. She also performs some of our specialized testing (OCTs and visual fields). As of May 2020, Felicity is on maternity leave. 


Natalie has been a part of our staff since 2012 and after a number of years working behind-the-scenes on clerical tasks, she joined our front desk team in 2019 and has been an excellent addition to the reception staff. With her kind and friendly smile, Natalie is integral in taking care of our patients' needs both while checking in or when phoning in with an inquiry.

We welcomed Sharri to our team in 2017 as one of our receptionists. She has a number of years of experience working in the eye care business. She always greets our patients with a smile at the front desk and also performs some of our additional testing (OCTs and visual fields) as well as training our new contact lens wearers on proper insertion, removal and care. She is a wonderful addition to the office!


Originally with us since 2008, our former reception team member Dana has rejoined our staff in 2020 after taking a few years off with her young children. She is responsible for much of the behind-the-scenes clerical work necessary to get our patients booked and keep our office running. We are thrilled to have her back with us! 


Christine joined our staff in 2020, bringing with her over 5 years of experience in the eye health care field. She is a member of our front desk and pretesting team and is also trained to perform some of our specialized testing. She has been a wonderful addition to our growing DOC family!


Another addition to our team in 2020, Nicole is working with us part-time as a pretester as she completes her undergraduate university education. She is interested in pursuing a career in a health care field and has been able to gain valuable patient care experience during her time here.
