Dr. Prepchuk holds bachelor degrees in Biochemistry from the University of Lethbridge, Canada and in Dentistry from the University of Sydney, Australia.

He believes in the importance of offering a complete range of services to his patients and has yet to discover an aspect of dentistry that he doesn’t enjoy. He loves the interaction with people, the intricately detailed work, and the active learning environment that dentistry provides.

After 14 years of practicing dentistry in Australia, he and his now-grown family have moved back home to Calgary to settle, trading the sunny beaches and kangaroos of Australia for the snowy mountains and grizzly bears of Canada.

Her love of working with her hands and interacting with people steered her right into the career of dentistry. She enjoys all aspects of dentistry, with special interests in root canal treatments, extractions, and orthodontics.

Tiffany likes to think that being an amateur triathlete has helped her to achieve her goals in life. The sport instilled the positivity and perseverance required to attain her Canadian dental certification through the challenging equivalency process.

When she is not practicing dentistry or training for her next race, Tiffany loves to travel, or explore the world of Netflix in the comfort of her own home.

Dr. Jessica Thomas

Dr. Jessica Thomas graduated as a general dentist from The University of Alberta in 2006. Ever since her graduation, Dr. Thomas’ passion has been working in “esthetic dentistry”. Recently, Dr. Thomas made the decision to limit her practice to providing esthetic dentistry and neuromodulators (Botox and Dysport) and is only seeing patients that have those specific esthetic dentistry and neuromodulator needs.

Within her practice, Dr. Thomas is especially passionate about cosmetic bonding – a conservative and economical alternative to veneers. While it is true that bonding is not always the best option, Dr. Thomas’ esthetic dental practice provides alternatives to bonding with veneers, crowns, bridges and implant crowns. Dr. Thomas’ practice goal is to always satisfy the patient’s desired dental outcome in the best way possible. Dr. Thomas feels that the best outcomes are achieved when each patient is provided with an in-depth understanding of the options and outcomes available to them. This understanding of options and outcomes allows each patient to feel confident to make an educated decision that is best for each patient’s personal situation.

Dr. Thomas has reduced her clinic hours to accommodate her family’s recent relocation to the United States. Dr. Thomas is committed to maintaining her role at Sierra Dental and continuing to provide esthetic and neuromodulator treatment to anyone who wishes to choose her to help them achieve the smile they dream of. Dr. Thomas is pleased to be able to offer digital consults through email, Instagram (@beyondsmilesyyc) or through doxy.me.

If you are interested in working with Dr. Thomas – do not hesitate to personally reach out to her at jessica.thomas@sierradental.ca or you can call us at the office to request an appointment for a consultation.
