She has had experience in several general and pediatric practices in Pennsylvania and Ohio before relocating and joining our office in 1988. She regularly attends continuing education classes to stay current with the most up-to-date dental developments. Over all the years of working in this practice, Tilly has never gotten over seeing patients transform their smiles and dental health.

Tilly and her husband, Phil, enjoy going to Redskins games. On a nice day, you'll find them beating a little white ball around the golf course! They have two children. Their daughter, an Auburn University graduate, lives in Atlanta, and their son also graduated from Auburn University and lives in Kentucky.

Janet is a chairside assistant and has worked in family practice for over 30 years. She received her training at Montgomery College and is certified by the Dental Assisting National Board in Radiation Health and Safety. Working in the same practice for so many years has enabled her to really get to know the patients and their families and better care for them. After all these years, she still loves and is excited by the advances in dentistry!

Janet and her husband have four grown children and enjoy traveling and visiting with them.


Karen was happily added to our team in                January of 2014.   Karen has nearly 30 years       of dental assisting experience and has proven       to be a hard working team player.  Given                her experience, it is no surprise that she has          acquired excellent assisting skills.  Karen says         it has been a joy learning about our patients.                               


Karen and her husband Ernie have two grown children and six grandchildren.  When she is away from the office, she will most likely be found at the family camp in West Virginia.

Beth and her husband live in Olney where they enjoy fixing up and decorating their western-themed home.
