Dr. Grace attended McMaster University for her Bachelor of Health Science Honours degree with distinction.  She completed her Doctor of Dental Surgery with distinction at the University of Western Ontario, where she was hounoured with a prestigious award for crown and bridge from the Toronto Academy of Dentistry.

Dr. Grace has built her practice with an emphasis on compassionate and conservative dentistry.  In the past, Dr. Grace has travelled to remote dental clinics in Paraguay and Brazil with mobile dental units and medications on a boat, to provide dental care for the less fortunate.  Today, Dr. Grace remains an active participant in a volunteer organization called Health Mission Outreach where she provides dental care for the underprivileged in the Greater Toronto Area. While providing dental care for the poor in makeshift clinics has its challenges, these meaningful experiences have helped Dr. Grace discover her passion in rebuilding smiles.

Dr. Grace is proud to have served her patients for over six years, and is well –versed as a caring, professional provider of all dental services, with a strong focus on rebuilding smiles conservatively.  Your smile is a reflection of who you are and is many times the first and most lasting impression you make on others. Dr. Grace believes that everyone deserves a healthy smile and strives to work with patients to achieve that!

In her spare time, Dr. Grace enjoys scuba diving, piano playing, curling up with a good book, and above all, spending time with family and friends.
