Our Patients Say it Best
- They got me in immediately, which first I thought was amazing. But to be honest, there was two points during my three root canals that I almost fell asleep. Never have I ever had that type of experience at a dental appointment. I highly recommend them. Very pleasant and heart warming.read moreread lessExcellent experience with a professional team. Great customer service, friendly staff and doctors. Dr. Diamond is very knowledgeable and explained everything well. He answered all questions and did a thorough exam. I highly recommend this clinic for Endodontist care.read moreread lessDr. Diamond and the entire staff at NCE were amazing! They were able to get me an appointment the very next day and the procedure was truly painless! I hope I don't have to have another root canal, but if I do, I am definitely going back to Dr. Diamond and NCE. Thank you all!read moreread lessDr. Bergo and Alex were an incredible team taking excellent care of me for my first root canal. Dr. Bergo updated me throughout the process so I knew exactly what to expect. He frequently checked to ensure that I was comfortable and not feeling any discomfort. I am very grateful for his kindness and care as I was a bit disappointed that my tooth needed a root canal. He was reassuring and eased my mind. Thank you, Dr. Bergo and Alex for a wonderful appointment.read moreread lessThis week I needed a root canal. Everyone has heard horror stories of how painful this procedure is. Well, I have to say that Northern Colorado Endodontics staff, all I met, are so good at what they do! All were professional, understanding, knowledgeable and are passionate about what they do. I had no pain during the procedure and recovery was rapid for me. I highly recommend them if you’ve been told you need this kind of work done.read moreread lessNeeded an emergency procedure after pain went from zero to one hundred over the course of 48 hours. These folks fit me in within hours of calling. Dr. Levalley and staff were very pleasant, professional, and efficient. I can't recommend this place enough.read moreread less
- This place is the best for root canals for anxious AuDHD patients. They aren't stingy about numbing injections and they go slow so it doesn't hurt as much. They tell you about whatever they're doing before hand, they give you a blanket to be more comfy, and there was no pain while he was working. Numbing wears off quickly for me, so I needed a couple of additional injections, one being inside my tooth and they al helps immediately. I normally cry after appointments like this, but it was so comfortable that I didn't. Beautiful office as well. I would recommend that they put up a "tour of the office" on their website for anxious patients to feel more prepared for what they are walking into. Only other recommendation is to position the tvs to where the parent can see it when they are laying back and getting work done. It was at an angle I couldn't see at all so I just kept my eyes closed, but my ADHD could have definitely used watching TV during the appointment so I wasn't soo bored and crawling out of my skin.All around I think this practice is to be trusted if you are anxious, especially Dr Geraets and Maddy because they were both so kind.read moreread lessThis place is amazing! Everyone was very pleasant, personable, helpful & professional. Loved the views of Lake Loveland while waiting for my procedure to begin. Dr. Lantz and his assistant were very pleasant, reassuring and I felt no pain during my root canal. All went very well. I would highly recommend this practice for your endodontic needs.read moreread less
- Dr. Colby Dimond and his staff were absolutely amazing!! They got me in the same day that I called for a much needed root canal. As someone who has never had a root canal, I wasn't sure what to expect. The entire process was pain free and quick! I highly recommend NCE to anyone needing dental work, the staff here is wonderful and incredibly kind!! You will not be disappointed!!read moreread lessI was in a lot of discomfort and very glad when I called on a Friday morning that they could offer me an appointment that morning. Dr. Lantz and his assistant were very professional and were good communicators. They did the evaluation and then the root canal procedure with great skill and it was effective! What a blessing to be relieved from the pain and stress.read moreread less
- I was blown away by the skill and efficiency of this office! I was in extreme dental pain. The front office staff went above and beyond to try and get me seen sooner. Dr. Brad saw me early, performed a root canal, and I left the office Pain free and 24 hrs later, I remain pain free. Thank you!!!read moreread less
- Dr LeValley and Evan were the best. I don’t think anyone likes a root canal, however, I couldn’t ask for a better experience. They were skilled, caring and knowledgeable. Letting me know what was going on at all times and ensured I was comfortable. Thank you!read moreread lessMy experience with Northern CO Endodontics and a rootcanal was very positive. The staff was very welcoming and friendly. Dr Geretz and his assistant were very informative and explained what and why they would be doing during the procedure and what to expect. It was a very and professional experience and I was kept very comfortable throughout.read moreread less
- I had been experiencing some discomfort over the past few months, and assumed it was from my root canal a while back. But Dr. LeValley explained to me that it was most likely due to my bite instead, and that it could be attended to by my dentist. Thanks also to Allie for supporting my visit with the X-rays and prep.read moreread lessThis was my first ever root canal. After a few days of constant pain I was there in the chair. The problem was an infection under a crown. The crown came off, and that was a good thing. Now they prepeped what was left of my tooth for a new crown. Feeling much better!read moreread lessI was in terrible discomfort with an infected tooth. I waited too long to get help but once I called, they saw me immediately. Sidney was very compassionate on the phone. Dr. LeValley and assistant Aly were understanding my fear and helped me relax . They worked quickly to get the root canal done so I was out of the chair ASAP and going home. Highly recommendread moreread less
- I was nervous about getting a root canal and the whole thing was super fast and almost entirely pain-free. The only part that hurt was getting the shot for the numbing medication, which is to be expected. Once the numbing set in, I didn't feel anything at all. This is different from other experiences I have had where I still feel a bit of nerve pain, even after the numbing meds set in.read moreread lessthey were able to accommodate me in a short notice emergency situation, and provided excellent services. Dr. Kimball explained the root canal procedure clearly and it went exactly as planned. i have healed very quickly with minimal pain. Their interaction with my primary dentist was also great allowing me to get the final filling done quickly before heading off on a vacation. Highly recommended.read moreread lessDr. Bergo and his assistant were knowledgeable , friendly, and above all skilled. I was warned before each "pinch" "pressure" "drilling" there was never an issue. Never felt more than some pressure. I recommend highly. This was my second visit the first 2018. If need be...I'll be back.read moreread lessDr. Bergo was great; explained everything in a compassionate manner which for me is a huge plus because a dental office is my least favorite place. Was a good experience. Lots of laughter when I came in the door among the staff and that speaks volumes to me. I was there for a consultation and glad my dentist steered me in this direction.read moreread less
- I gave Dr. Garaets a 5-star recommendation because my dentist recommended I see *someone* for a root canal, but Dr. G said "NO, you don't", and explained why. A less reputable person might have performed the root canal and no one would have known the difference. Of course, he charged me $386 for the exam, but I can only complain so much about that. I received professional service in a timely manner I called on Monday; he saw me on Wednesday. That's worth a lot.read moreread lessDr Diamond and his staff are extraordinary. He has helped me out three different times with root canals and done an exceptional job and I didn't feel a thing!! He's a diamond in the rough!! His assistant was very pleasant and both were very concerned with how I was doing the whole time we did the procedure. Your receptionist also was extraordinary, fit me right in was extremely helpful. She helped me with directions and also help me with insurance information. I couldn't ask for better service.I will highly recommend all of you and be back if needed. Thank you so very much. I really appreciate all of you. Mary Culverread moreread less
- The office/reception staff at the Fort Collins office are phenomenal. I don't think I have EVER encountered nicer or friendlier people at a place of business in my life (I'm 48)! Every time I have called they have been very friendly and helpful and understanding and have solved my issue (scheduling/rescheduling). The Greeley receptionist was also very nice, friendly and helpful (when I arrived and when I left). Dr. Diamond has done 2 root canals within 3 weeks and he was great! He's friendly and gentle and tells you along the way what he is doing. In the Greeley office the dental assistant that was assigned to me was absolutely AMAZING (her name was Drea- not sure on spelling)! Her personality and kindness and caring attitude were perfect!read moreread lessI recently had an apicalectomy and root canal at this office, and the care was exceptional. The procedure was smooth, and I had minimal discomfort afterward. The staff were incredibly friendly and made the entire experience much more comfortable. Highly recommend!read moreread lessPolite, friendly receptionists. Assistant was friendly, professional, responsive. Dr LeValley was warm, professional, very easy to talk to, included my input in the treatment plan... but best of all, he was honest and said I didn't need the treatment I went in for. That was money out of his pocket and empty time for him. This is the kind of professional that you want working on you.read moreread less
- I had a lot of anxiety coming in for a root canal, as my last experience with one was quite unpleasant. However, NCE Fort Collins got me in almost immediately (within 2 hours of my call). I was really suprised to not have any pain or soreness during the procedure or afterwards. The team was very professional & efficient. I would definitely recommend NCE and would personally trust them with any future needs.read moreread lessExceptional. I felt so comfortable and in good hands. They explained things even more clearly than my normal dentist does, gave me a clear after-care plan and were so wonderful and personable the whole time. Their technology seemed advanced and specialized and definitely go the job done. I would definitely recommend them.read moreread lessI am the DEFINITION of a "problem patient" - difficulty getting fully numb, extreme anxiety, TMJD- you name it. When I scheduled my appointment for a root canal with Dr. Dimond, terrified doesn't even beging to adequately describe how I felt. If I had a hard time getting numb for fillings... A root canal?!? BUT- Dr. Dimond and his staff were the most professional, kind, and skilled people from which I've ever had dental work. I went from 1000/10 anxiety (even WITH the sedation), to 1000% confident that painless dental work is possible when you go to the right people. Root canal on upper molar was 100% pain free the entire time. Localized anesthetic shots were 100% pain free. I couldn't believe it. Thank you thank you thank you!!!!!read moreread less
