Our Patients Say

I never thought that I would say this, but I love coming to see my dentist! Everyone in this office is super nice and accommodating. I love my experience in this office every time that I have an appointment. I look forward to my visits here.

Olga A.

Face it, nobody likes going to the dentist. I get that. But I actually look forward to my dentist visits because of the people! Everyone here is so nice and non-judgmental it's been my pleasure to go here for going on 5 years now! They also know what they're doing, which hasn't been my experience in the past. I am consistently confident that they will take care of my mouth when I go here!

Clint D.

I've been a patient of Dr Floor and team for over 20 years. Now my whole family goes. It's a great team, always proactive, keeping up with technology and will go out of their way to help you.

Yvonne L.

Always a great experience at Floor Dental Group! It's like catching up with long-time friends every time we visit. Everyone is outgoing, friendly and professional. My kids and I have been driving from Redwood City to see Dr. Floor for many years now and we wouldn't think of going anywhere else.

Alecia T.

It's always a pleasure to visit Floor Dental Group for my dental care. Everyone in this office is friendly and professional and I know they provide the best care.

Vera R.

As a patient scared of dental procedures Dr. Floor and his staff are considerate of my "phobias" learned as a child. As a senior citizen now the care taken with general and even more specific procedures is a blessing for one who needs this work done. Great job!
