Awesome dentist and super friendly dental hygienist. I’ve been going here for years and our whole family loves Sarah(hygienist). Receptionist is very sweet and helpful and knows her insurance stuff and will help you get your appointment as soon as you need it. I had never had laughing gas during dental work before but it helped me relax and not worry about a thing while Dr. Kooker was working on my teeth. I have been a patient at two other dental offices before(one on west side of Plano and the other in Carrolton) and by far, Dr. Kooker is my favorite because it is a small office with a family feel to it and I feel so well taken care of there.
