I absolutely love this place, literally everyone that works there is friendly and attentive. They are so knowledgeable and really take the time to meet your needs. I’ve never been to such a great dentist, I highly recommend them! You’ll be customer for life!


Dr Klein is the best dentist I have ever had, without a question. I am one of those people that has anxiety around the dentist. Dr Klein makes himself available if I have questions or concerns. I feel like I am part of their family and that's the kind of practitioner I want.


Extremely clean and safe for these days of precaution. Every consideration is taken for everyone’s safety. Dr. Klein is the most skilled dentist we have ever been to. Every procedure is explained. Completely trust Dr. Klein and his friendly staff.


I LOVE this place. Everyone is so kind and they work with your schedule. I'm glad I found my new forever dentist office. Dr. Klein is the best dentist I have ever been to. His office is very comfortable and his staff is #1.


I have been a patient of Dr. Callahan for over 30 years and love smile he gave me! I am now seeing Dr Klein and am so happy he joined Dr. Callahan. He is very personable and a great listener!


Callahan & Klein Dental is the exact experience you WANT at the dentist. Friendly faces from the minute you walk in the door until you leave! Amy cleaned my teeth and took my x-rays and she was absolutely fabulous. I had such an amazing experience that this is now our family dentist! I will be taking my 2 year old daughter in for her happy visit and my boyfriend is going to get his teeth cleaned there too. I LOVE this dentistry, and literally will not go anywhere else from now on!


I am a new patient here, and Dr. Casey Klein is far and above the best dentist I have ever had the pleasure of seeing. I was thoroughly impressed by not only his professionalism, and of his staff, but of the bedside manner and consistent updates of the processes being delivered at the time of delivery. He went above and beyond that which was explained to me for my initial visit. I am looking forward to having this new dentist in my life for many years to come!


This is the first dentist I have found in Colorado I really like and trust. I had a front tooth that I broke in half as a child that was kind of pieced together when I was kid and was starting to fall apart. Dr. Callahan put a new crown on my front tooth and it looks amazing. You can’t even tell it’s a crown and it’s literally my front tooth. Everyone I’ve interacted with at the office is really nice and kind and helpful too.


This is a fantastic family friendly office. The staff are attentive, listen and truly care. I prefer my dental care be on the more gentle side and everyone here has been so great about that. Dr. Klein is very good about explaining everything he is doing. Kathy is thorough in her cleanings and great to make sure I am doing ok through out the entire experience. Sarah is fantastic with kids who are a little unsure of the dental experience. I am so pleased with the care my family receives at Callahan & Klein and I highly recommend the entire staff for your dental care.


The staff are professional yet very caring and make sure that I have a chance to let them know how I am doing. Dr. Callahan has been my dentist for 23 years - he's amazing! I have seen Dr. Klein also and he's kind and very thorough - :) Great practice!

Step of your procedure.

Our family has been a client for decades. I drive across the city to go to this dental office, and it is worth the journey. Both doctors are excellent in every way, from expertise to considerate patient care. Recently Dr. Klein was especially sensitive and helpful to discuss and schedule a series of appointments in light of my financial situation.
