I have been seeing Dr. Dahler for 3 years now. I had to switch from my primary dentist due to dental insurance changes with my job, and I was panicing because I was comfortable and extremely happy with my old dentist. I got the 5280 magazine issue regarding top dentists in Denver, and Dr. Dahler was listed among them, AND his office was close to my house. I went to the office for several cleanings over the first 2 years, and I was made to feel welcomed, comfortable, and happy by the receptionist, hygienists, and the doctor himself. Dr. Dahler is young, enthusiastic, knowledgeable, and has a great sense of humor. It's not your usually stuffy, uncomfortable environment.
Not long after I found Dr. Dahler, I had to have a crown put on a broken tooth. I am terrified of needles, so I begged him not to use one. Of course, he pretty much insisted that I have the pain numbing injection due to any possible discomfort that could occur during drilling, etc. When I came back for the actual procedure, he and the hygienist were prepared with my favorite music playing and all sorts of hilarious banter to keep me focused on anything but the needle. It worked, and I barely felt it. Most other dentists would simply tell you to deal with it, but I really appreciated the way they handled the situation without making me feel stupid or childish.
Additionally, Dr. Dahler is excellent at cosmetic dentistry - my front teeth have a genetic defect, and he is handling it with bonding. Overall, it's really nice not to fear going to the dentist.
