I had a gap between my front teeth that had to go, so I scheduled an appointment with Dr. Unterseher to discuss my options. Though I could do regular braces, we both agreed that Invisalign would be the best for me. I paid up front (thanks, insurance that didn’t cover a dime of it!) and got started right away. The office is really nice and in a very handy location. My opthamologist and dermatologist are also in the same building, so getting there was a snap. The dentist chairs all face north, so you can watch the activity at Lodo’s Bar and Grill while you wait. The view of the mountains is fantastic. All of the assistants are so nice, making you feel really comfortable. I always feel like I have Dr. Unterseher’s undivided attention when I’m there, and I never feel rushed. Though his clientele seems to all be under the age of 15 he doesn’t talk down to me at all. I really feel like we explore every last one of the options at every turn. I ended up getting five sets of Invisalign trays, going in to get new ones every three weeks. A few of the sets were pretty painful the first few days, but it wasn’t bad at all. I wore them for 22 hours every day. I started Invisalign a year ago and I’m happy to report that the work done through this office was absolutely stellar. I have no complaints at all. My teeth look great, and I know that the issue won’t come back. Yes, I’ll wear Invisalign trays for at least eight hours a day for as long as I have my teeth, but they’ll always be straight and where I want them. I see Dr. Unterseher about every three months now, just for quick checkups. Great office! They’ve taken very good care of me

I really love this practice! I went for braces as a teen (07) and my teeth shifted due to my own fault. Went back for Invisalign just recently. Same great service. Quick and straight to the point. I wouldn’t have came back if I didn’t believe Dr.U and his team were the absolute best! My aligners came in in less than a month, was in and out of my appointment in less than an hour. They’re a dream team.

My family have been patients here for years! I always feel so welcome and confident that 2we are getting the best treatment possible! Love Dr. Ron and the staff. Especially Kim! She is so knowledgeable, and will help you with any cost or insurance questions you have! Not to mention the views at the office are outstanding!

” Both my daughters are patients and every time we go the staff is always so friendly and informative of what is going on and gives politely lets them know when they need to do a better job of brushing or flossing. The atmosphere is very comfortable as well. I would refer to anyone looking for orthodontic care “

The staff is incredibly friendly and welcoming. I would call out specific people but it’s everyone! Dr. Unterseher took the time to show me the exact areas and types of corrections needed and explain what it would take. Being an adult patient, they were sensitive to my appearance needs through treatment as well as making accommodations for payment as my insurance doesn’t cover adult braces. Haven’t had a bad experience yet.

My son had a complicated orthodontic situation, so we’ve been involved with Unterseher Orthodontics for almost 5 years. Dr. Unterseher has done a brilliant job! And I can’t say enough about his wonderful staff. Everyone we have worked with has been very skilled and caring, and I am so grateful for their ability to help my son get through some of the tougher parts of the work that needed to be done. Thomas got his braces off last Monday and he has a beautiful new smile!

I wish there were more stars to give – awesome service every time I go from the front desk to the assistants to the doc. You guys are fast, super friendly and always explain what you did and why – My youngest will be wearing your braces shortly as well, and I always recommend people to you first. Thanks!

This team is there with you from the beginning to the end. There are not there to gouge you out of your money! They were very up front on there pricing and had different payment options. We were seen months prior to my child having braces put on to checking on growth and movement of there teeth while they were still growing. Just to ensure that when they did put the braces on it was the RIGHT time. Because of this care I have decide to get Invisalign for myself and also have my 7 year old look at to see how his teeth are progressing.

This is a friendly and cheerful office with state of the art equipment, yet very reasonable pricing. Dr. Unterseher and his staff make an effort to ensure that their patients feel that their best interest is a priority. I really appreciate the way they went out of their way to accommodate my special need with expertise and would recommend Dr. Unterseher to any individual or family looking for orthodontic care,

My experience with Dr. Ron and his entire team has been absolutely incredible. I couldn’t be happier with it. Everybody is accommodating and attentive. Dr. Ron makes you feel super comfortable and taken care of. I am convinced he picked the best treatment plan for my fairly complicated situation. After a year and a half I’m almost done with my treatment, my teeth already look amazing. Everything is changing exactly as the doctor planned. My bite has changed exactly as it needed to change and my teeth are super straight. I did invisaligns and it worked very well for me. I feel like doctor Ron is super knowledgable and professional in what he does. I would recommend him to anyone who wants quality service. I am beyond grateful to have picked him as my doctor!!!

From the moment I entered Dr. Unterseher’s office, the staff treated me as if I was an old friend! The office is beautifully decorated and everyone is very professional. I was seen right away and was able to start my treatment right away. They even worked with my insurance provider to help me pay. It was a great experience and I would highly recommend them!

ANY adult seriously considering braces or aligners needs to at least come here for a consultation! I was in and out within 90 minutes. I got pictures taken, scans of all kinds done, consulted with Dr. Kim and Dr. Unterseher, set up a payment plan and paid my deposit for my Invisalign aligners all in that time frame. I can’t forget about how gorgeous and conveniently located this office is! Delmy was also super friendly and professional when she was doing my scans. I felt really comfortable being here. They use OrthoFi which gets rid of the daunting $2000 down payments most dentists ask for. YOU choose your down payment AND what you’re comfortable paying monthly. They even have options with 0% interest!! I had to sign up right away. Aligners will arrive within 2 weeks and I am incredibly excited

I have had a positive experience every time I bring my 3 sons to visit Dr Unterseher. From the very beginning, I was given a tour of their facility and even got to watch Dr Unterseher work on my boys. This put any doubts I had at ease and made me feel comfortable. He explains the treatment plans and goals in great detail, and includes me in on the decisions that need to be made. The entire staff is friendly, knowledgeable, and upbeat. But we miss the happy receptionist who use to work the front desk at the 104th/Federal location. I feel bad that her name has escaped my mind but she would always put a smile on my family’s faces. My sons never had any complaints nor have they ever been reluctant to come to any appointments. I’m also thankful for their payment plans……because fitting 3 kids with braces….ALL AT ONCE :/ can cost a pretty penny no matter where I go. They even offer discounts for multiples. Thanks to all of you! Love this place and will definitely recommend to others in need of a straight smile.

” Dr Unterseher and his staff are always amazing. They have helped me through so much on my journey going through my second set of braces, and jaw surgery. I chose them because of how welcoming and knowledgable everyone is. I decided to not go back to my former Orthodontist because I was unhappy with the results I received. Since I needed braces again for Jaw surgery I decided to go somewhere new. I found Dr. U, the office location is great & now there are two locations. Ree and Renee always love to chat with me and answer all my questions and scheduling needs. The girls are always so kind and gentle with me when I go get my wires tightened. Go here! Everyone is wonderful you won’t be dissapointed! 🙂 “

Dr. Unterseher has always greeted us with a warm smile and inviting atmospheres. We have been going to his office for over 22 years ( 6 children and myself). I have highly recommended his business to both family and friends through the years. His staff is friendly as well as professional. Anyone who walks into his office and is greeted by Rhi, Jenny or his other staff make you feel as if you are one in a million. Their expertise is evident in their mannerism and work.

” We had visited your office last year for an initial exam for Katie. We had also visited several other orthodontists in the area to get a consultation. We decided to postpone our treatment for awhile before making a decision as to where to have Katie’s treatment. We received several follow up calls and cards, which were very much appreciated. The timing was right for us to begin Katie’s treatment this summer, and when we called back, the staff was more than willing to work with us to schedule Katie’s appointments. The staff is friendly, accommodating, and we feel very confident in having Dr. Unterseher and his staff be the ones to work with us over the next few years. Thank you for the great service! “
