The work Dr. Tran did was exceptional. I have received services two times now for separate issues. The care from everyone in the office is the best. You feel at ease as soon as you walk through the door. I recommend them to everyone.

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!

Amazing! Amazing! I can't thank Dr. Tran enough for taking care of my surgery. He is such a nice human being, and very polite addressing issues. This office is truly amazing and all the staff members are very helpful. Joyce is always helpful. I recommend them at anytime.

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!
Carson F.
My experience with Dr. Tran today was a 10 out of 10. It was absolutely painless and so incredibly professional. I would recommend everyone I know who needs a root canal to see Dr. Tran. Going to get one is not fun but he made this experience very pleasurable. THANK YOU so much for taking my pain away and for being so amazing. Joyce and Kelly were great too!
Dana C.

Dr. Tran is truly top-notch at what he does -- fast, skilled, and so reassuring throughout the entire process. I felt completely taken care of and confident in his expertise.

I had a root canal almost a week ago and it went very well. Dr. Tran did an excellent job and I experienced very minimal pain during this procedure. I remain pain free today and I would definitely recommend Dr. Tran. I will return to this office if I have future endodontic needs. Thank you!

Michelle
Needing a root canal to save one of my Molars wasn’t something I wanted to do. I met with Dr. Tran who reviewed the problem and rationale for doing the root canal. Dr. Tran was so kind, professional and patient with my questions and concerns - we proceeded with the procedure and I was pleasantly surprised how smoothly it went. The assistant and Dr Tran were in sync with each other and they kept me informed of each step in the process. I am very pleased to highly recommend this calm, clean and professional Practice for your endoscopic needs! And the receptionist was efficient and very kind and professional.
Ashley R
Easy to get to, very organized and extremely friendly and helpful staff!
Pat W.
The endodontist is not always at the top of people’s list of things they look forward to, but these guys make it easy. Absolutely top notch.

I had my second root canal at Centennial Endodontics and although that is never a fun procedure, the folks at the office make it a much more bearable process. Dr. Tran, Joyce and Kelly are wonderfully attentive and caring people who made sure I was well cared for. It’s a very peaceful environment, from the soothing music and aromatherapy fragrance in the waiting room, to the comfy chair in the procedure room. I was there last year and I really wanted some place closer to home for this year’s root canal but after careful thinking, I would have been foolish, given last year with the same team was a very good experience. Highly recommend and if I need another root canal, I’ll be ringing them up.
Julie W
I would refer this place to anyone these people are very helpful and trustworthy unlike some other places this place cares for their patients.
Aaron M
I had an infection and needed a double root canal. Dr. Tran performed the procedure. The most painful part was the injection of the anesthetic, which was actually quite minor. Dr. Tran applied temporarily fillings to the teeth. When I went to my regular dentist to have the temporarily fillings replaced with permanent ones, my dentist commented that Dr. Tran had done a great job!
James D
Dr Koh and his team were awesome, easily the best experience I’ve had for a procedure I didn’t want. I usually wait too long when told I need to get dental work done, and frankly despise going to both the dentist or endo. Like I said, Dr Koh and the staff were personable and smooth. It was the least uncomfortable I’ve ever been for procedures like this. I highly recommend this practice.
Tyson H
My procedure went great. Very pleased with Dr. Tran and his assistant.
Rosemarie C
They are the best, Dr Tran explains everything and made me feel really comfortable.
