Meet the Doctors

Dr. Jeff Diefenbacher 

I received my Doctorate of Dental Surgery in 1995 from the University of Toronto, Faculty of Dentistry. I was the recipient of the Colgate-Palmolive scholarship for Excellence in Preventive Dentistry, the S.A. MacGregor Award for Pediatric Dentistry, and the Keith Box Gold Medal for Periodontics. I joined my father in this practice in June of 1995, and we worked together  for 2 years, at which time he retired after 43 years of dentistry in the KW region.

When I am not at the office I can easily be found on a "course" -- whether it be a continuing education or golf. In addition, our family spends a great deal of our downtime relaxing at our cottage up North.

Dr. Jackie Sieber

I am a graduate of the University of Waterloo, Ontario with a Bachelor of Science in Health Sciences followed by a Doctorate of Dental Surgery from the University of Toronto in 1997. I was a recipient of several awards including the Keith Box Gold Medal for Periodontics. I particularly enjoyed oral pathology and microbiology. I spend a lot of my free time at continuing education courses, keeping current with my dental knowledge. I am proud to be a volunteer for Jeans 'N Scrubs, community wide fundraiser that raises money for our local hospitals. jeansnscrubs.ca I recently participated in a dental mission to Guatemala with Health Outreach.  This experience certainly provided me with a new perspective of basic needs missing in the lives of many children around the world!  I have been practicing in the KW area for almost 15 years.   I am a family oriented person, cherishing time with my husband and 3 wonderful children, including 4 yr-old twins!  I also enjoy cooking, travelling, gardening, pilates, yoga, tennis, and stand up paddleboarding.

Dr. Abby Donovan

 

I graduated from the University of Guelph in 2007 with a Bachelor of Science in biological Science, and received my Doctor of Dental Surgery from the University of Western Ontario in 2011. I travelled to Tanzania with MedOutreach - a student run organization at UWO that provides dental screenings and treatment to those in need in Tanzania. 

I was born and raised in Kitchener and am excited to be living and practicing in the KW area. In my spare time  I enjoy hot yoga, cooking, skiing, and spending time with family and friends.
