It wasn't Dr. O that I saw. I was seen by a hygienist (Amy), and Dr. George Carere. The care provided was exceptional. Very friendly, very thorough and very comfortable.

Very pleasant, professional, patient and understanding of someone who has fear of the dentist.

I’m so glad I decided to make the switch to Trillium Dental. Everyone I met was so friendly and welcoming. The hygienists and Dr Hussein were gentle and put me at ease. Thank you for the terrific service!

Excellent dentist. Efficient and friendly.

Dr. O and her assistant are very nice. During examination, they are gentle and explain thoroughly what needed to be done.

Trullium Dental was welcoming and comfortable. Dr. O and the dental hygenist, Kristine, were caring and provided a thorough and stress free exam and cleaning. Dr. O definitely has a passion for promoting good oral hygiene. Booked an appointment for my daughter as well.

I really enjoyed my visit. And that's saying something as going to the dentist in the past has always given my anxiety a workout. As soon as I was sat in the chair they put me at ease And we're friendly and funny. No judgements which, again, is rare in my experience. So glad I found them and look forward to continuing with Dr. O and associates.
