I was so nervous to go to the dentist but Dr Keen explained everything and I felt so much more relaxed. He was awesome and I was very comfortable getting my procedure completed. I highly recommend his calming nature and detailed explanation.

Fabulous dentist!
I moved into the area from out of state and was concerned about finding a good dentist. A co-​worker recommended Dr. Keen and he is great!
The office staff is very kind and take care of all of my insurance claims very efficiently.
He recently replaced some 40 year old fillings for me and was so careful, gentle and concerned about me well-​being during the two sessions needed to replace 7 fillings.
My wife and I both go to Dr. Keen and recommend him to everyone.

Dr Keen is an awesome dentist! I have been going to him for many many years. He really takes the time to make sure you are comfortable through out all procedures. He also put veneers on my front teeth a few years ago and I constantly get compliments from strangers about how perfect my teeth are. He really is the best!

Dr. Keen deserves a great review. I quit going to my last dentist when I just could not take the pain and long, long appointments. Dr. Keen is not like that! I have been going to him for about five years. During that time, he has had to fix some work that was done by my last dentist, and his work is far superior. There is no comparison. He works in a calm and careful manner, and lets me know exactly what he is doing. I always feel comfortable.

Great dentist and wonderful, warm, competent staff. My only wish would be that they were located a bit more off the beaten path: it’s not in the most modern of buildings and the parking lot is a bit of mess. But I’d go to MUCH worse places to get this fantastic service.

I am very surprised that I’m the first person to write a review for Dr. Keen.
For some people it is very difficult to see the dentist. The fears of root canals, more appointments, extractions, and pain are the worst. Dr. Keen, removes ALL those fears. I’ve moved around quite a bit in the last 12 years, and whenever I get a new dentist I use Dr. Keen as a reference to what a great dentist is. After 3 dentists, I find myself commuting to Rancho Cucamonga, as he is the only dentist that makes me feel at ease.
He is very professional and does great work as well.
I hope this review helps.
