Geoff Barnum, DMD

Owner Dentist

Geoff Barnum grew up in southern Idaho and is the third of four children. He attended Idaho State University, where he received his Bachelor's degree in Biology. He took a leave from his studies to serve a Christian mission in South Korea.

While studying at Idaho State, he met his beautiful wife Becky. They have been married for over 14 years and have 6 children together. He enjoys spending time with his family when he is not in the office.

Dr. Barnum completed his dental school training from Case School of Dental Medicine in Cleveland, Ohio. The family enjoyed their time there but ran away from the bitter winters and have called Texas home since 2011.

Dr. Barnum continues to learn about new dental techniques by taking continuing education courses so he can provide the highest quality of care to his patients.

Dr. Barnum was very involved in athletics and outdoor activities as a youth and continues to enjoy these today. He enjoys frequenting all the local restaurants and can't get enough Tex-Mex!

Tiffany

Office Manager

Tiffany grew up in Joshua, TX. She is the oldest of 4 siblings. After graduation she had a passion to serve people and went to school to become a Medical Assistant. After several years of working in the medical field she was ready for a change.

That exciting change came when Tiffany joined the Polished Family Dental team. She is married and has 4 wonderful children. In her free time you will find Tiffany camping or on an outdoor adventure somewhere.

Sarah

Hygienist

Sarah has been with our team since 2016 and has been a dental hygienist since 2002. She educates our patients about oral health and what they can do to achieve it. She loves to have fun with her job, and always tries to have a laugh with our patients!

We treat some truly special people in our office, and it’s a joy for her to get to know each one of them. In her spare time, she enjoys gardening, fishing and watching her pup, Sister, grow!
