Dr Gary and his team are excellent! I have a lot of dental related anxiety and he and his team made me feel so comfortable with everything during my cleaning! Couldn't thank them enough!

Today was my dentist appointment and I was a bit nervous since I had a bad experience somewhere else and all the staff made me feel like part of their team! I was so relaxed and left feeling great about my cleaning! Thank you all!!!

Dr. Demetriou and his staff were super accommodating to get me in quickly when I had serious pain and discomfort. Chrystal was thoughtful and concerned about my pain from handling my initial call to ultimately recommending an oral surgeon who cares about people in my predicament. Such a culture must start from the top. Thank you Dr. Demetriou! I also like your style relating to the cool office decor.

Dr. Demetriou is amazing. I’ve been going to him for years and even though I relocated I still continue to see him. He did a last minute root canal on me today, which was done perfectly (this is coming from someone who is extremely afraid of doctors and very sensitive to pain ).The staff is very friendly and professional.

So I write this review with a heavy heart, because I personally like this dentist. Nice guy. But we are talking about my health here and I think I need to warn people.

I was a patient here for a few years and left to go somewhere else. I left because of a few reasons...the primary reason being that every time I came here whether it was for a cleaning, or for a cavity, it was painful. Sometimes the Asian dental hygienist, who's English was ok but not fluent, would take that metal scraper thing and dig into sensitive areas even after I told her to be careful. I came to dread cleanings. When
