Our exceptional, friendly team is our greatest asset. We are excited about what we are doing, and we are motivated to achieve the best results for our family of patients.
I am a graduate of the University of Toronto, receiving my Doctorate of Dental Surgery - Class of 95. I was the recipient of the Colgate - Palmolive Scholarship for Excellence in Preventive Dentistry, the S.A MacGregor Award for Paediatric Dentistry, and the Keith Box Gold Medal for Periodontics.
Upon graduating, I joined my father in private practice, and I had the pleasure of working with him for 2 years, at which time he retired after 43 years of dentistry in the KW Region.
I am passionate about continuing education, which helps me stay current in my private practice. I am an elected member of the Ontario Dental Association's Education Advisory Committee, whose prime directive is to provide continuing education for dentists and their teams. As such, I get to travel to conventions throughout North America, looking for new speakers to bring back to give lectures in Ontario.
Outside of the office, my wonderful family keeps me very busy. Our 3 kids are involved with a number of activities and there are a lot of days where we have to divide and conquer. We intentionally do not enroll our kids in any extracurriculars through the summer months so we can spend as much time at the cottage on Georgian Bay as a complete family unit as possible.
I have a deep connection to the KW community, being born and raised here. In addition to supporting my wife’s philanthropic activities, I play an active roll coaching a girl’s hockey team. Our office sponsors our children’s hockey/ ringette teams, and we also choose to sponsor one other sports team during the winter and summer months. I am passionate about supporting the arts in our community. We are longtime supporters of the Black and Gold fundraiser for the KW Art Gallery, as well as Corporate Sponsors of the talented KW Symphony.
I was honoured by the Ontario Dental Association with a Merit Award acknowledging my contributions to the Profession of Dentistry. I was also awarded a Fellowship in the Pierre Fauchard Academy.

Jackie is a graduate of the University of Waterloo with a Bachelor of Science in Health Sciences, followed by a Doctorate of Dental Surgery from the University of Toronto in 1997. She was a recipient of several awards including the Keith Box Gold Medal for Periodontics. She particularly enjoys oral pathology and microbiology.
The rapid changes in dental technology have kept her passion for her career ignited, especially with the positive difference she can bring to many through Invisalign, clear aligner therapy. Jackie enjoys staying current with her practice through continuing education, by attending conferences and listening to webinars. She puts a lot of effort into keeping the office patient-friendly through design (yes our water cups must match the office colour scheme!) down to the careful magazine selection (boasting a very current and broad collection!)
Jackie doesn't like sitting still, so she packs a lot of things into her free time away from the office. Having three kids keeps her on her toes, especially in her second career, as their Uber driver! She never thought she would enjoy being at the rink as much as she does, and no, she will not admit whether she likes ringette or hockey better! Jackie enjoys cooking, travelling, SUP and tennis. She is a proud volunteer for many charitable organizations and truly loves being involved with community-wide fundraisers that raise money for local hospitals, and mental health organizations.
Recently the office has initiated two large philanthropic enterprises including The Belmont Vibe for the Child Witness Centre, as well as Old Bags of Westmount, with proceeds going to HopeSpring. Jackie has been involved with Health Outreach by completing a dental mission in Guatemala. This experience certainly provided her with a new perspective on the basic needs missing in the lives of many children around the world! She was honoured to be the recipient of the Ontario Dental Association’s Award of Merit. Finally, and most importantly, Jackie would like to thank her parents Bev and Joe Sieber for their support in allowing her to achieve her dreams. Love you.

While in Dental School, I travelled to Tanzania with MedOutreach - a student run organization at UWO that provides dental screenings and treatment to those in need in Tanzania. This is something I aspire to do again in the future.
