I highly recommend Dr. Daren King. He has offices both on Carroll and on Union St. in Park Slope. He has a busy practice, strictly limited to orthodontry, and he is a true professional. We are finally about to get the braces off and we'll be ending our relationship with Dr. King, but I recommend him with no hesitation if your child needs braces. The office (on Union) is cramped but the atmosphere is friendly and all the staff members are very professional.
