  • I love this office. You are treated better than just a patient. When we walk in it’s a cozy environment and you are greeted with warm smiles. Dr. Witkowski and his staff really take the time to work with you and your needs. I have always been terrified of the dentist so when I went in for dental work Elizabeth completely put me at ease and it was the most painless experience I ever had. There are so many wonderful things to say about this place but what I like the most is that I’m remembered. The staff asks me how my baby is doing, they remember that I get nervous easily and it’s just a good feeling. Miranda
  • I’ve been going to Green Oak Dental for a while now and so happy with the great care I get there. The ladies in the office are always welcoming. I’m not afraid of dental appointments anymore since I feel confident and at ease that Dr Mike will provide excellent care. Patricia L
  • Dr. Mike fit me in on an emergency basis last Thursday. His staff was warm and welcoming. They made me feel very comfortable and at ease immediately. The service, staff, and atmosphere was all amazing. I am so happy to have a great dentist so close. I highly recommend Green Oak Dental to everyone. Laura P
  • Dr. Witkowski is wonderful. He really cares about his patients and their specific needs. He takes the time time to explain procedures and helps put your mind at ease if you are one of those that are nervous to go to the dentist. The ladies in the office are very friendly and helpful. Cari F
  • "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!"

  • "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.
