Carolyn O'Leary

Financial Coordinator

Hi, my name is Carolyn and I live in Urbandale, Iowa. I grew up in Winterset, a town southwest of the Des Moines area. My grandparents owned a farm in rural Peru, Iowa and that is where I spent most of my summers and weekends. My husband and I have lived in the Des Moines area for most of our married life. We have two grown children and two wonderful grandchildren, two cats and a dog named Ivan!! When I’m not working, I enjoy scrapbooking, reading, gardening, decorating and some traveling. Anyone who knows me will tell you that I am a State Fair junkie!! I look forward to the fair every year and can give you a countdown for opening day! My favorite color is red…my favorite animal is cows…my favorite pastime is shopping!!!!

I will be working with you regarding your dental insurance needs. I have worked in dental office environment for over 8 years. It will be a pleasure working with you and your children here at Walnut Hills Pediatric Dentistry.

Jamie Smith

Dental Assistant and Front Office

Hi, my name is Jamie. While originally from North Carolina (Go Tar Heels!), I currently live in Waukee. I attended Wayne Community College in North Carolina. My husband and I have two little girls and two moody dogs who constantly keep us on our toes. Nobody warned us they developed such strong personalities so quickly! My rigorous training at home has prepared me for anything your little ones throw my way! My other interests include reading, riding bikes, and being a wannabe DIY’er.
