Libby

Registered Dental Hygienist

I am a graduate of the College of Southern Nevada’s first dental hygiene class more than 30 years ago. I’ve worked in many dental offices in the Las Vegas area. I have been with Siena Dental since 2002. I am here to provide comprehensive dental hygiene services to our patients. We are here to serve you, our patients.

The continuing education courses I attend allow me to provide the most current and effective periodontal therapy, as well as educate my patients about the latest hygiene products and theories essential to their oral and overall health. Certification in both laser periodontal therapy and local anesthesia allows me to provide a comfortable dental experience for our patients. I’ve been married to the same great man for over 38 years and have three wonderfully unique and dynamic children.

I have two grandkids that I brag about all the time. It's what grandparents do! Aside from work, I enjoy traveling abroad. My husband and I have visited Rome, Berlin, Prague, Vienna, southern Germany, and Switzerland, and we finally got to explore Paris and northern France. We paid our respects at the D-Day Beaches as well as the American Cemetery. I loved seeing Monet’s Garden in Giverny, and I even took a cooking class in Paris! I look forward to seeing you at Siena Dental and ensuring you have a pleasant experience here.
