As a dentist, I can be quite critical of my dental experience and this office was top notch. Grace was very accommodating at fitting me in at a late notice request. I was very pleased with the professionalism and quality of the care I received. It is a beautiful office and very friendly team.

We have been going there for over 20 years and have had the best experiences. First with Dr. A. Hawryluk Sr. (Deceased) and now with Dr. Steven.

I found Dr. Steve accidentally but I have become his permanent patient since then. He is so careful, professional, patient, and polite. He considers your concerns and even after your treatment session you always can call and book a post treatment session if necessary. So I’m sure that my teeth will be treated as best as possible and even after the treatment I can come back for any possible issues. I wish all the best for him and his family!

The professionalism is over the top. Alan’s skill is a given but his demeanour makes the difference on a very difficult procedure.

Dr Steve and his lovely Assistant (forgive me, don't recall her name), have, in effect, completely eliminated what was previously for me, an extreme dental phobia that kept me away for over 15 years. My last appointment which included repairing a broken molar and a very deep cleaning was completely stress and pain free! I'll be their regular loyal patient for as long as I still have teeth!! Thank you both so much! James
