I have traveled to Belize, Central America with Project Smile and have also observed dentistry in Istanbul, Turkey. I am truly blessed to work with such an amazing staff and am honored to be part of an office where we all make the benefit of the patient our primary goal!

 Julie Walterman- Hygienist

I have been working with Dr. Gleixner since 1999. I graduated from the IU School of Dentisty in 1988. My family has lived  in Greenwood for over 20 years. My husband, Joe, and I have been married since 1988 and have 3 children Tony, Drew, and Erin. I enjoy playing tennis, spending time outdoors, and going to concerts. I consider myself very fortunate to work with our staff which I consider family.  Dr. Gleixner shares my philosophy of treating all patients as if they are family members.


 Cindy Ernst- Front Office and Chairside Assistant

I attended Aristotle College and have been working with Dr. Gleixner since 1986. My husband, Gary, and I live in the Center Grove area and have three grown children. I have a STRONG love for animals and am a volunteer at Southside Animal Shelter. I also enjoy spending time on our family farm in Morgantown and love having “Get togethers” with family and friends.

 Elizabeth Rubalcava – Chairside Assistant
 Tracy Gleixner – Administrative Assistant

My primary role is behind the scenes but you may find me stepping in to assist at the front desk. 

Mark and I were married in 1985 and I have been part of the administrative side of the office ever since. Along with my responsibilities in the office, I worked at Merrill Lynch until 1989 and then joined Computer Systems Design. At Computer Systems Design, I assisted dental offices in computerizing their office and training on software. My passion for the financial and technical side of the business continues and I always look forward to continuing education and advanced technology.

I enjoy meeting our patients and getting to know about them and their families!
