Meet the Dentists



Dr. Thad Gillespie, F.A.G.D.

Raised in Wichita Falls, Texas, Dr. Gillespie graduated from Midwestern State University and attended the University Dental Branch in Houston, graduating in 1980. After dental school, he had the honor to serve in the United States Air Force and was stationed at Wiesbaden Regional Medical Center from 1980 to1984. During that time, he received several honors, including the Defense Meritorious Service Medal for work identifying the Marines who died in 1983’s Beirut bombing. He also served on the team that examined and treated hostages who were released from Tehran.

Dr. Gillespie returned to Texas in 1984 to work as an associate with Dr. Maury Hafernik. In 1985, he started his own practice in northwest Austin. A new chapter began in 2001, when he opened a practice in Liberty Hill (40 minutes northwest of Austin). At ease treating patients of all ages, Dr. Gillespie enjoys working with people to develop oral health plans that will serve them well in the long-term.

A member and Fellow of the Academy of General Dentistry, Dr. Gillespie is a mentor of the Kois Center and was a teaching associate with the Hornbrook Group. He also serves as the dental director for Samaritan Health Ministries in Cedar Park, Texas. This organization treats indigent patients or those who do not have medical coverage. Dr. Gillespie also runs and is owner of the Dental Genius Assisting School which teaches interested students how to become successful dental assistants. Active in the community, Dr. Gillespie sponsors many sports teams, as well as assists with the Headstart Program in Liberty Hill, Leander, and Georgetown, providing exams, treatment, and classroom education.

Dr. Gillespie and his wife, Kerstin, live with their children in Liberty Hill, on a 30 acre ranch. They are involved with their children in the area schools, sports, FFA, and the Liberty Hill Marching Band.  The Gillespie Family enjoys camping, fishing, cooking, and free time together. Kerstin, a Registered Nurse, and Dr. Gillespie shared the vision to bring a state of the art practice to Liberty Hill. Kerstin served as office manager and helped Dr. Gillespie build the practice after it first opened. She looks forward to working with Dr. Gillespie on the building project for a new, larger Liberty Hill practice in the near future.


Dr. Tiffany Georgiefski

Liberty Hill Dental would like to welcome our new Associate Dentist, Dr Tiffany Georgiefski.  She works in our office on Mondays from 8:00 am – 5:00 pm and Thursdays from 12-7 pm.  Dr. Georgiefski is a true native; born in Austin, raised in Leander and alumnus of Leander High School. Following high school, Dr. Georgiefski studied at St. Edward’s University where she would ultimately graduate magna cum laude with a Bachelor’s of Science Degree in Biology. Upon her graduation, she travelled southbound to Houston where she would attend the University of Texas School of Dentistry. After four arduous years in Houston, she successfully earned her Doctor of Dental Surgery (D.D.S) degree.

Dr. Georgiefski aspired to be a dentist from a very young age. The inspiration initially came from a complete smile makeover television show, and quickly grew into a commitment to help others improve their smile and oral health. Dr. Georgiefski believes that every patient should be treated like family, and she hopes to build life-long relationships with all of her patients. When she is not practicing dentistry, Dr. Georgiefski enjoys spending quality time with her two sons and husband, Robert, and two puppies, Zoey and Minnie.
