    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!

    I was referred here from friends, and I can tell why they raved! Everyone in the office is so kind and efficient. Happy to have a new dental care team that really listens and have great energy. Definitely makes the dentist less of a pain (pun intended!).

    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!

    Dr. Kosta’s office always leaves me heading out the door with a smile. His assistant Sofia was so kind and gentle during all of my X-Rays. Dr. Kosta always has such great attention to detail. Every experience I've had here has been far above the typical standard! Thank you Dr. Kosta and Staff!!
