Originally from Mansfield, TX, Dr. Audrey is a native Texan.  She attended UT Arlington for undergrad, then went on to attend Baylor College of Dentistry. Soon after graduation, she began working in Texas with a primary focus on kids. It was in this time that she developed her love for pediatrics. After 8 years of practicing, she decided that her calling was to go on to a pediatric dentistry residency and further develop her knowledge and skills. She is currently in her 2nd year of her residency at the UNLV School of Dental Medicine.

Her passion is not only providing great dental treatment to children of all ages, but also for her family. Dr. Audrey and Dr. R.J. have 2 amazing little boys named Jameson and Jackson. They love to spend time together as a family as much as they can.
