As I enter my 20th year as an educator in the Howard County Public School System, I am overwhelmingly excited about the opportunity to serve as the Principal of Murray Hill Middle School. I am a product of Howard County Public Schools as I attended Talbott Springs Elementary, Clarksville Middle School, Harper’s Choice Middle School, and I am a proud graduate of Wilde Lake High School. I attended Howard University, in Washington, D.C., where I earned a B.A. in English and my Masters of Education. I am committed to providing an engaging academic environment for all students and building a school community in which the well-being of each and every one of our students is consistently the priority. I look forward to working with the MHMS staff to provide our students with challenging and rigorous academics as well as meaningful experiences to enrich their growth and development. I look forward to all of the staff and students at MHMS stretching themselves to achieve their ultimate potential. Please note, that I can be contacted at lisa_smithson@hcpss.org.

The core of who I am as an educator/administrator is that I have a passion to make a difference in the way young people feel about themselves and to provide opportunities that will put them on a path to not only be a productive citizen, but also allow them to live a life that makes them feel fulfilled. My educational background is as follows: Bachelor of Science in Elementary Education at Bowie State University, Masters of Art in Reading Education at The Ohio State University, and Graduation Certificate in School Administration and Supervision at Johns Hopkins University. I began my teaching career in Worcester and Wicomico County Public Schools on the eastern shore of Maryland, where I was born and raised. There, I taught all core subjects from elementary to middle school grades. Later, my husband, our three children, and I moved to Howard County where I taught English/language arts and was a reading specialist at the middle school level. All of my children are graduates of Howard County Public Schools. Since 2011, I have been the Assistant Principal of Murray Hill Middle School. As I enter my 27th year as an educator, I continue to look forward to a new school year - a chance to better serve the students, staff, and community of The Hill.
