We are honored by the trust our patients and referring doctors place in us. Hear directly from our patients about their experience, comfort, and successful outcomes at our practice.
Highly recommend!! Such a good experience when it could have been an overwhelming one. No pain, no swelling, no bruising. Now just waiting for the healing. 😊 Great “chair side” manner. Answered any and all questions. Great group!
Diana G.
Highly recommend!! Dr. Koh & his staff are amazing! Had to get a Root Canal done and i was very nervous about it. He explained everything very thoroughly. His assistant made me feel extremely comfortable and had me laughing! The procedure was done so quickly I was amazed! Not painful one bit! 10/10 for sure!!! Thank you for making this experience a great one for me!
Ashley R.
I wish I could give Dr. Jason 10 stars. Hands down the most professional, welcoming dental office I’ve ever been to. He has gone above and beyond to take exceptional care of my son, and make him feel comfortable during visits. We are very thankful to have him locally.

The team here is amazing! I had an extremely stubborn tooth with 2 calcified roots that my usual dentist just couldn't quite get through, so they referred me to Dr. Koh! He is so kind and clearly a master at his craft! I can have rough dental anxiety but this space was very calming and safe. I knew they cared about me, not just my teeth! Highly recommend!!!
Jordan S.
I have never experienced such great dental care in my entire life! The entire staff was incredibly kind, and I absolutely enjoyed how welcoming and compassionate they were! Dr. Koh did a fantastic job with my Root Canal and I would highly recommend Greeley Endodontics to anyone and everyone needing any work done! You won’t be disappointed with your choice!

Who new getting a root canal could be fun?! Alright, maybe not fun, however Dr. Koh and company made it a stress free environment and fun when they could while keeping my comfort level and best interests in mind the entire process. Don't really want to go back but if another root canal is in my future I will be going to Dr. Koh.
