I have been a Dental Hygienist with Downtown Dental since 2005. Over the years I have built a loyal client base who entrust me with their dental health. I always enjoy the interactions with my patients as we often share stories and occasional laughs.

As a Hygienist it's always nice to meet new clients and make people feel comfortable and at ease; especially for those who have dental anxiety.

Welcome to our practice! My name is Meghan and I am one of the friendly Registered Dental Hygienist that work at Downtown Dental Associates. I have been a part of the Downtown Dental team since July 2017.

Furthering my strong belief and love for education, I then obtained a degree from Brock University in Adult Education and a Masters of Higher Education for Health Professionals from the Ontario Institute for Studies in Education at University of Toronto.

Many of my friends and clients describe me as bubbly, talkative, and loud! I love cleaning and I have been known to be very thorough and extremely gentle. If you have required numbing during your cleaning in the past, you won’t with me. In addition, if you wish to learn more about any specific dental products, please feel free to ask. I am certain to have an opinion which I am happy to share.

When I am not cleaning teeth I enjoy traveling, hanging out with my dog, and EATING (always open to new restaurant recommendations)!

Looking forward to meeting you and having you leave Downtown Dental Associates with a (clean) big smile!
