The most kind dentist I have ever met. I used to hate going to the dentist for anything! Even while carrying dental insurance, I wouldn’t regularly go for cleanings. Since finding Dr. Kuhl’s practice I don’t dread any of my dental appointments. The hygienists are sweet and gentle (and were so accommodating for me while I was pregnant and couldn’t lay back). Dr. Kuhl has never steered me wrong with his advice and I genuinely enjoy talking to him. Positive, clean, and respectful environment!

Dr Kuhl and his entire staff are wonderful. They make you feel like family from the minute you walk in the door. My appointment was at 9, and I’m always early for everything. They took me in before 9. They explained every detail of what they were doing and did not rush through anything. I was so impressed with the whole experience. I had no pain or discomfort at all. I honestly can’t speak highly enough about Dr. Kuhl and his team. I am a new patient, but now I’m one for life. Thank you for making going to the dentist such a pleasant experience.

Dr Kuhl and his staff were great! I went in for a third opinion due to being told I had 12 cavities by one dentist and 3 by a different dentist plus a fancy laser for deep cleaning for an additional 1,500$. Long story short Dr Kuhl was happy to see me with my previous X rays which were not that great quality so they performed they’re own X-ray and waived the fee. Dr Kuhl found 3 cavities and treated one that was some-what urgent. I was told the laser was a waist and the staining on my teeth was not that bad. I did not feel pressured to get anything done during the length of the visit and was treated exceptional! Thanks again!
