Just had my final visit today after 18 months! Mergen and staff have always been friendly and professional, and I haven't had a bad experience in my time with them. The facility in Iowa City is always so clean. You can trust that they are thorough in their work and that they actually care about the service they provide.
Out of all of the business I've visited throughout my life, Mergen Orthodontics has been the best experience yet. Dr. Mergen is wonderful! He's kind, understanding, great with children, and a fantastic orthodontist. The staff is also phenomenal. They are all very welcoming, knowledgeable, and accommodating. Oh, and they're incredibly efficient. We've never waited more than a minute or two. Having Invisalign as a young child is a big responsibility. Our daughter did pretty well. However, whenever an issue did arise, everyone was immediately there to help. They all made this a wonderful experience, and I would highly recommend them to everyone!!
My twin daughters established care with Dr. Mergen at age 9. Their permanent teeth were coming in and were very crowded. I honestly wasn't sure what kind of results he would be able to get because their mouths were so small, but I trusted his process and the outcome was amazing! Our dentist had been concerned that one of the girls was missing a permanent tooth, but Dr. Mergen made space for all the teeth to come it properly. I can't recommend Mergen Orthodontics highly enough.
If you're considering Invisalign, do yourself a favor and come to Dr. Mergen! He and his staff are all so incredibly friendly, welcoming, and professional. I'm almost done with my treatment plan and I am extremely happy with my results. All of my appointments were quick (the longest I've had to sit in the waiting room was about 2 minutes) and Dr. Mergen and his staff did a phenomenal job of checking my progress and laying out each part of my treatment plan. I cannot recommend them enough; you are in good hands with Mergen Orthodontics!
Dr Mergen and his staff are professional, friendly, and make the whole experience wonderful. If you feel you have horrible teeth and embarrassed, there is no shaming here. I even lost a tooth due to chemo and they were very professional and even provide next step and contacted my dentist for me. The visits are fast and they are very accommodating to fit your schedule. I would recommend and know you are in good hands with a very experienced staff. P.S. Not to mention my teeth are beautiful again. It's never too late, I'm in my 60's!
