Dr. Kosta is not only the nicest and most professional dentist I’ve been to, but the best. He removed my wisdom teeth quickly and painlessly, and because I told him I’m squeamish about that kind of stuff he made sure to keep me distracted. Wonderful dentist and staff!

Dr Kosta is always so gentle and kind. He also explains what he is doing before he does it, which is a huge help for me because I am a total chicken 🐔 I highly recommend him!
