Registered Dental Assistants


Kendra began assisting right out of high school and worked at a general dentistry office for 4 years. She graduated from ACC Dental Assisting School in 2008, joined Round Rock Periodontics shortly after, and is now the lead surgical assistant.

Aside from assisting Dr. Arastu, Kendra loves spending time with her husband, Shawn, and son, Kason. He makes sure to always keep her on her toes, but she enjoys every minute of it. Some of their favorite things to do together are fishing, watching him play T-ball, and spending time outdoors. Any time spent with them, even if it’s just lounging around, is time well spent.

When asked why she loves her job, with no hesitation, she said, “definitely the patient relationships. Knowing you are one of the reasons they look forward to returning is rewarding.” She says that working for a great dentist and team makes coming to work easy because we are like one big family!


Holly joined Round Rock Periodontics in 2001. She likes working at Round Rock Periodontics because she loves working in such a friendly and family-oriented atmosphere, meeting new people, and helping patients feel better about themselves by providing great dentistry. Holly says that one of her favorite parts of her job is seeing how much happier and more confident patients are when they see their newly restored smile.

At home, Holly enjoys spending time with her husband, Justin, and two kids, Summer and Westin. She also has two dogs, Rogue, a Belgian Malinois, and Cadence, a Shih Tzu.
