Dr. Atwal

Dr. Harpreet Atwal:
“I love practicing dentistry and working within a profession where I can utilize my training and skills to help make a difference in peoples’ lives one smile at a time. The one-on-one interactive nature of my profession gives me the ability to connect with my patients. Because of this, I have come to know that my patients are some of the most interesting people I have ever met. I love when they share their life stories and experiences with me. Thanks to my wonderful patients, my practice has evolved to not just knowing and caring about my patients’ mouths, but to knowing and caring about the person as a whole and unique individual! I look forward to getting to know you, and providing you with the highest standard of oral care, in a relaxed and comfortable setting.”

Dr. Harpreet Atwal completed an Honours Bachelor of Science degree from York University majoring in Biology. She was the recipient of the Faculty of Pure and Applied Sciences Silver Medal. This distinction is awarded to the graduating student who has combined outstanding academic achievement with the greatest contribution to undergraduate student life. She then went on to complete her Doctor of Dental Surgery degree at the University of Toronto. After graduating, she gained a variety of experience working in several clinics in Northern and Southern Ontario.

Dr. Atwal believes participating in continuing education, and staying abreast of all the latest developments in the dental field is of utmost importance. This allows her to provide the most cutting-edge treatment to her patients. For this reason, she is an active member in the dental community. Some of the professional organizations that she is a member of include the Canadian Dental Association, the Ontario Dental Association, and the American Academy of Cosmetic Dentistry. Dr. Atwal is also an associate fellow of the Academy of GP Orthodontics and a Preferred Invisalign Provider.

Dr. Atwal was born and raised in Toronto, Ontario. She is happily married, and she and her husband have two beautiful children.  In her free time, Dr. Atwal enjoys reading, travelling, and spending time with her family and friends.

My name is Samie Jean, and I am an international student from the Turks and Caicos Islands. I have been in Canada for three years.

I enrolled in the Pre-Health program and graduated with honors, that is when I decided to enroll in the dental hygienist program. As a young child I have always wanted to help others and that is what I intend to do in my path as a dental professional, help my patients achieve the best oral health as well as maintain their beautiful smiles.

Hello my name is Tricia and I have worked in Dentistry for 20 years, having been a hygienist for 16 years. I entered this profession after working for the Toronto Star Newspaper for several years performing both proofreader and advertising editing functions. I love healthcare and the ability to both educate and help improve one's oral health. It's rewarding to visually see the positive results of a client’s oral health over the process of visits. My spare time consists of reading, crosswords, skiing, skating, swimming, boating, rollerblading …. anything in the beautiful outdoors!!

Cheers, Tricia
