The entire staff are friendly and knowledgeable. I needed a quick turnaround for a crown, and Dr. Leeman got me in the next day. Always checking to make sure I was comfortable during the entire procedure.

Staff is always friendly and helpful. They explain things well in regard to procedures, follow-up care, and financial options available. I’ve been getting my dental care done here for many years, and have never been disappointed. Thanks!

Friendly, caring staff. The family became clients of Dr. Hanneman in 2001, and have now seen Dr. Leeman 3 times. They both are wonderful! Wouldn't dream of going to any other dental practice.

I have been coming here for 25 to 30 years. I am always happy with the services from the staff, Dr. Hanneman and Dr. Leeman. Everyone is very knowledgable, helpful, personable, and kind. I highly recommend them for your dental needs.

Dr. Leeman and his staff are the kindest, most caring and gentle people in the profession! I've always hated going to the dentist, but not any longer. They are like my friends. I highly recommend that if you are unsure about where you go now...go to Oshkosh Smiles! You will be glad you did!!!

I have been going to Dr. Hanneman for 20 plus years, and they are absolutely the best. When I go there, I feel like I am part of a family. A lot of their staff have been there as long as I have been going there. Very caring people.

Seriously love going here. The staff all make me feel so comfortable even with the anxiety I have. On top of it all I broke my ankles recently and received a get well card. It meant a lot to me. I’d highly recommend to anyone to come here. Thank you again for being so awesome and so thoughtful!

Mike and staff are a good group. They work well as a team and I trust their expertise. Most of my appointments over the years with them have been regular checkups with nothing unusual, but they've put a couple crowns on my teeth and they've fixed some fillings. They've always done good work and are pleasant/personable.

I have been seeing Dr. Hanneman and staff for 25+ years and wouldn’t think of going elsewhere! The entire staff is so friendly and knowledgeable. They are always considerate of my time, and they love what they do.
