Katie - Front Desk

While spending the first twenty years in the Smoke Rise area raising our five amazing children, my husband John and I recently became empty-nesters. Of course, we still love spending time with the kids, especially those precious grandchildren. I’m a true “foodie” who loves to create in the kitchen. I also enjoy running, yoga and gardening. Working with the Killian Hill Dental Care has provided me with the opportunity to connect with other community members while surrounded by caring and professional co-workers. Each day we strive to provide friendly and exceptional service to each and every patient. The reward for me is to witness the end result: a fabulous smile!

I live in Lawrenceville with my husband Ryan. We have three sons, Parker (born in 1997), Jack (born in 2000), and Aaron (born in 2004). I enjoy reading and you can always find me at the park watching my sons play baseball. I've enjoyed working here since April 1993.

I enjoy spending time with my children and all of their activities. Working here is a pleasure; the staff and the patients are wonderful.
