I have been coming to Dr. Darien for basic and complex dental work since I was in high school (I'm 30 now), and I do not bother seeing anybody else because he excels in what he does and has superb customer service, and I'm always surprised how much he remembers about me even when I haven't seen him in 6-9 months. Even though I live quite far from his office now, I always make the trip to go see him and I always check with my insurance to make sure he will be covered under it when I switch insurances.
