Practice administrator

Kathy Rupenthal

Hello, my name is Kathy and I will be  the first smile you will see upon entering Rupenthal Dentistry. I love getting to know everyone and hearing all of your stories! My goal is to make you feel at home and also organize your dental insurance, or help with other payment options. You can count on me to help with any treatment or appointment questions you may have as well.  I can frequently be seen running around the office tending to the comfort of patients, offering water and blankets!

I was raised on the north side of Indianapolis and attended North Central High School. I graduated from Butler University in 1981 with a major in finance. My first job was as a loan officer for Merchants National Bank prior to joining Dr. Kurt at the dental office. Dr Rupenthal and I have three wonderful sons. (No dentists!) I am an animal lover of all types! Currently, we have two elderly ponies and two dogs.  Dr. and I love to walk the dogs on The River Road trail and we frequently see our patients, so please say HI!
