Meet the Staff

Krista Roberts - Hygienist

Krista Roberts - Patient Care Coordinator

Krista started with Armstrong Dentistry in early 2016. She has worked in the dental field since 2007 when she began in orthodontics. She continues to educate herself to stay current with the dental and administrative fields. She loves traveling, camping, and spending time with her family. Krista and her husband, Brandon, were married in October 2020 and have seven children between the two (four, his; three, hers) that keep them active. The four oldest are in college, all at different schools, so she needs lots of prayer to get through this time!




Lisa Zeh - Hygienist

Lisa Zeh - Hygienist

Lisa joined Dr. Armstrong's office in 2004, after receiving her degree in dental hygiene from Sinclair Community College. She is currently certified in CPR and local anesthesia.

Lisa and her husband, David, have two children, Payton and Kelsey. Lisa enjoys spending time with her girls, family and friends. When she’s not at a sporting event for one of her girls, she enjoys baking!




Mallory - Dental Assistant

Mallory Knapke - Hygienist

Mallory joined Armstrong Dentistry in 2021, shortly after receiving her degree from Rhodes State College in Dental Hygiene. Mallory graduated with honors, was president of her class, and received the outstanding dental hygiene student award. Mallory married her high school sweetheart, Aaron, in August of 2022. In her free time she enjoys reading, walking/biking, crafting, and spending time with family and friends.




Molly - Hygienist

Nicole Meyers - Hygienist

Nicole started in the dental field in 1998 as a dental assistant. She graduated with an Associate’s Degree in Dental Hygiene in 2002, and followed that with a Bachelor’s Degree in Applied Management from Ohio University in 2017. She is currently the Dental Service Manager at CareSource insurance company and is also a certified personal trainer, so overall health and fitness is very important to her.

Nicole and her husband Ric have seven children between them, and they also have three grandchildren.

They spend much of their spare time with their children, watching movies or working around the house. In their time away from the kids, they are either working out or riding their Harleys with friends. The only exception to this is during football season, when the Pittsburg Steelers take top priority over everything else!




Cameron Armstrong - Dental Assistant

Cameron Armstrong - Dental Assistant

Cam began her dental career as a chairside assistant while her husband-to-be, Mark, was in dental school. At the same time that Mark graduated from dental school in 1989, she graduated from Miami University with a BFA in graphic design. In the 31 years since, Cam has handled virtually all of the design work for the office while raising their four children. Their oldest, Andy Jane, graduated from Lake Erie College in 2015 and is an equine eventing trainer at Bascule Farms in Poolesville, MD. William is studying mechanical engineering at the University of Dayton and working as an additive manufacturing lab technician at the University of Dayton Research Institute. Jackson is studying computer game design at Kent State University. Calvin is a Corporal in the United State Marine Corps, with his MOS in Avionics. After her youngest began high school, Cam returned to the office primarily as chairside assistant and Director of Marketing, but will also fill in at the front desk when needed. Cam also recently earned her second bachelors degree, this time from The Ohio State University, in Russian language, with Honors. In her spare time, she relishes spending time outside working with her horses, taking long hikes, and enjoying nature with Mark and her children.
