What Our Kingwood Dental Patients are Saying

"My family’s dental health has been taken care of by Dr. Rowntree for over twenty years. He is always very conscientious and efficient. They file our insurance claims for us and are very clear about what a procedure will cost. We highly recommend this dental practice."

Toni C.

"Dr. Mike has been taking great care of our family's dental needs for many years. I can not say enough good things about him! He is knowledgeable, caring, and honest. I highly recommend." 

Laura P.

"Dr. Witkowski and his staff are absolutely wonderful, I have no bad words to say of them! They were the perfect balance of both professional and able to make you feel like family. I am from out of town and got my wisdom teeth taken out- and when I came home from the holidays, he took care of the pain I was having right away and didn't treat me any less than he would if I had been one of his regular patients. 10/10 would recommend!"
