Dr. Callender is exactly what you want in an orthodontist. We came from a larger, national chain orthodontist that was more of a money grab than anything else. Dr. Callender and his staff are that 'mom and pop' office that will get to know you personally and truly care about you and your needs. He does an amazing job of explaining exactly what he's doing and why. After each appointment with my child, he comes out to the waiting area and explains what he did, why he did it, and what he will be doing next. He is a wonderful orthodontist. I only wish we would have found him sooner.

With three kids who needed braces, we knew that we would need a good relationship with an orthodontist. After hearing great reviews from friends, we chose Dr. Callender to start braces on our oldest six years ago. We continued with our other two kids beause of the great service he and the office staff provide.One of my kids has a mouth full of challenges and he educated us about all our options so we could decide how to move forward with her orthodonture and future dental work. He always makes sure that my kids know what the plan is and what he is doing to modify their braces from one month to the next, and after the appointment, he always checks in to let me know how things are going.Dr. Callender and his staff are very personable. We appreciate the consistency - he has had the same assistants for years, and Lecy at the front desk is an absolute joy.

We have been going to the Arvada Office for about 3 years. They’re wonderful, Dr Callender explains everything that he’s doing or trying to accomplish. He also takes the time to step into the lobby & ask how you’re doing.

Most expert orthodontist and staff, kindest too, in Colorado. Reasonable prices. I've benefited for over ten years, from their special night guards--good for TMJ, bruxism, and sleep apnea!

Love the experience we are having with Dr. Callander. After beginning orthodontic treatment in another state we relocated to Littleton and needed to find an orthodontist to complete treatment. We interviewed a couple of them and both my daughter and myself found Dr. Callender and his office staff to be, by far, the friendliest and most welcoming. Dr. Callender took the time to go over our goals for her teeth and gave an honest and thorough evaluation and explanation of what would need to be done to get there. Not only that, but they were very understanding of my financial situation and have been completely fair in their pricing for the remaining services. We are always greeted warmly and seen in a timely manner.

Professional, knowledge, caring doctor and team. We recently moved here from out of state and I was looking for an orthodontist to continue treatment for my daughter. I have been so impressed with the explanation of the treatment Dr. Callender was going to do and the ease and comfort he provided my daughter. Totally recommend.

Dr. Callender and his wife and staff are all amazing. Every time I go into their office they are always so kind and get me in right on time and sometimes earlier which is great! I have a baby and they always are okay with her being there. I’ve had my braces on for a few months now and have already seen my teeth significantly move. Dr. Callender and his assistants are always precise when it comes to your plan. They always make sure that everything is in the right spot and that nothing is poking or unnecessarily hurting you. Dr. Callendar always makes great conversation and he is very meticulous and detail oriented which is exactly what you want to see in an orthodontist. His wife always remembers everyone’s name and bits and pieces to each and everyone’s life and that shows how much she cares about clients. The office is very clean as well and they always provide me with enough rubber bands when needed. When a problem occurs such as a bracket falling off or something getting moved in the wrong way they always get me in the same day to get it fixed. I appreciate all they have done for me financially as well they have been more than fair! They truly care about you at this office and I highly reccomend them. I can’t wait to get my braces off and see the beautiful work that they have done on my teeth!

Dr. Callender and his staff are amazing. They take the time to talk to us and really explain what's going on. I have a teenager and a pre-teen in braces at the same time. The staff works hard to try to make sure I can have their appointments together so that I don't have to make so many trips to the office. They still take the time to really get to know my children as individuals, so we don't feel like we're just "another patient." Our payments are done automatically, so I don't have to remember to call in or mail in a payment. They also give me courtesy calls before appointments so I remember where I'm supposed to be. All things considered, this braces process has been pretty painless! HIGHLY recommend!!
