My daughter went to him years ago. She just turned 30 and her teeth are still perfect. I hated my bottom teeth and was self conscious about them for... years.Dr. Shank and his staff are wonderful. Well into my 50’s I got braces. It was a wonderful experience. Dr. Shank said 4-6 months. It was just over four months and I could not be more pleased. Would recommend for adults as well as children.

Dr. Shank is amazing! He fixed my teeth beautifully over 10 years ago and they still look amazing today. He is always nice, genuine and truly care... about his patients. Even years later when I broke a piece of my glued in retainers he took time on his day off while I was in town for the weekend to fix them for me. Everyone in the office is friendly and caring. I’ve never had a single problem with them!read more

Dr. Shank and his his staff are A++. It takes patience to work with kids. This man has it. He is as calm and cool as they come. He puts my kids... at ease and has great a sense of humor and a ton of experience. He explains everything and is available on call should there ever be an emergency. Get there on time and you will be done on time. The staff is very courtesy and helpful. They will take the time work with you should you need to re-schedule or if you need to stop by because your child bent a bracket eating a forbidden granola bar. The office is neat, clean and tidy, with refreshments. These people are almost like family as I have been taking my kids there for 8 years between palate expanders, braces, and retainers. Whenever my kids question something about their dental appliance and routine I always say to them, "Trust Dr. Shank". You should too! He knows what he is doing.read more

Dr. Shank came highly recommended to me, and after finishing Invisalign treatment with him, I can see why. In my search of an orthodontist, I found... and consulted with several Invisalign treatment providers in the area. From the very beginning, I sensed there was something different about Dr. Shanks as compared to the other providers. Not only was Dr. Shank professional, he was also compassionate and genuine. His staff were always welcoming and accommodating. As a physician, I often ran late due to my own patients, but his staff went above and beyond to ensure I was seen. Wonderful experience…not to mention, straight teeth!read more
