Hello Mill Run Mountain Lions! I’m so excited to be back at Mill Run working closely with the greatest students, staff, parents, and community! I would really like to take this opportunity to tell you about myself and my experiences in education. I began my career as a special education teacher at Mill Run Elementary and remained as one for five years. During this time, I pursued my administrative endorsement and earned my Master’s degree in Educational Leadership through George Mason University. Once obtained, I was fortunate to be able to move into the Administrative Intern position at Mill Run. In 2011-2012, I became an Assistant Principal in Fairfax County Public Schools. Then, in 2012, I had my calling to come back “home” to Mill Run, where I am so proud to continue my career. Mill Run is such a special place for so many reasons, and I am ecstatic to be a part of this wonderful opportunity with your children.

I have a firm belief that all children can learn and succeed. My mission and passion is to prepare our children to be lifelong learners both in- and outside of the classroom. I am excited to be an active member on this journey to success, and I look forward to working closely with you to support our children in reaching beyond their greatest expectations. Should you have any questions or concerns, please don’t hesitate to contact me.

It is an honor to join the Mill Run community as the Assistant Principal.I am looking forward to serving the staff, students and community. 

Prior to Mill Run, I served as the Assistant Principal at Forest Grove, Dean at Steuart Weller Elementary and Sycolin Creek Elementary. I also taught kindergarten through third grade in both Prince William County and Loudoun County. I hold my bachelor’s and master’s degree in Elementary Education from James Madison University and my Master’s Certificate in Educational Leadership and Administration from George Washington University.  

It is truly a privilege and honor to be part of a community where families, staff, and students all care and work together for the success of all students. We understand and celebrate the unique qualities of all students and work to ensure that Mill Run continues to be a safe, welcoming and inclusive environment for all learners. 

I look forward to working together to provide the best learning experiences for our future leaders. If you have any questions or concerns, please do not hesitate to contact me.
