I am thrilled to begin my fifth year here at Trailside. It is so moving to be the 8th grade Dean, having transitioned with most of the students since 6th grade. Middle School is such an exciting time of growth and development; I am honored to support students and families along this journey.

My pathway to Middle School Education began at Radford University where I earned a Bachelor’s of Science. I continued my quest for learning at George Mason University where I earned a Masters of Education in Curriculum and Instruction as well as a Masters of Education in Education Leadership.

The 18 years I have spent in Middle School Education include teaching Math, Reading, Language Arts, and Social Studies. Additionally, I have been a Technology Resource Teacher and a Dean. All of these experiences helped me grow professionally and personally.

I live in Ashburn with my husband of 21 years, our three beautiful daughters, my father and his dog Harley as well as our Boxer, Buddy. We live an active life centered around our daughters’ activities. When I am not cheering on my girls at softball, soccer and dance, I am routing for the amazing Pittsburgh Steelers! The moment you step into my office, it is obvious that I am an avid Steeler fan.

I am looking forward to a wonderful 8th grade year! I want to ensure our students have a positive and strong finish to middle school as they develop the grit, resiliency and self-advocacy that will lead to success in high school and beyond. Please know that I am happy to help you and your student with any questions or concerns you may have. Feel free to contact me at 571-252-280 or e-mail me at
