I am entering into my 19th year as an educator in Howard County.  I am excited about continuing as the Principal of Triadelphia Ridge Elementary School. I am a product of Howard County Public Schools as I attended Talbott Springs Elementary, Clarksville Middle, Harper's Choice Middle and Wilde Lake High School. I graduated with a B.A. in English from Howard University and also earned my M.Ed. from Howard University. I am committed to providing an engaging academic environment for all students. I will continue to work with the TRES 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 TRES stretching themselves to achieve their ultimate potential. Please note, that I can be contacted at lisa_smithson@hcpss.org.

Greetings! I am excited to introduce myself as the newly appointed Assistant Principal of Triadelphia Ridge Elementary School. I grew up in Howard County and attended the University of Maryland, College Park, where I earned my Bachelor's Degree in Early Childhood Education (Go Terps!). I then earned a Master's Degree in Curriculum, Instruction, and Administration through McDaniel College. This will be my 12th year as an educator in Howard County, having served at Gorman Crossing and Swansfield Elementary Schools. In addition to being a classroom teacher, I had the unique experience of being a Title I Intervention Teacher before moving into my role as Assistant Principal at Swansfield Elementary three years ago. I look forward to meeting each and every one of you and working with Mrs. Smithson and the TRES staff and community in order to best serve and benefit our students. Please do not hesitate to contact me throughout the year with questions or concerns. I can be reached by phone (410) 313-2560 or by email at heather_moraff@hcpss.org.
