  • Hello all,

    I will be going out on maternity leave within the next few weeks and wanted to let our Mary Walter Community know that you will be in excellent hands! Below is an introductory letter from my long-term sub, Heather Sheffer. Please direct absentee emails and clinic questions to her email during my absence. I will be back in February and wish you all the best until we meet again!


    Kelly Piselli, RN



    Hi Mary Walter Families!


    My name is Heather Sheffer and I will be your substitute nurse while Mrs. Piselli is on maternity leave. I am excited to get to know all of you and your children, but rest assured that Mrs. Piselli has given me a full update on all of the students so that I can seamlessly pick up where she left off.

    For a bit about me, I have been a nurse for about a year and a half and have previously worked in a hospital setting. I obtained my Bachelor of Nursing from George Washington University and I also hold a Master’s degree in Biology from Chatham University. I live in Bristow with my husband who is a high school teacher and football coach, along with our 1.5 year old son and our two dogs and five chickens. In our free time we enjoy being outside, catching a local football game, or the latest superhero movie.

    I look forward to getting to know you all better during these next few months. If you have any questions or concerns please do not hesitate to call the school clinic at 540-422-7715 or email me at


    Best wishes,

    Heather Sheffer, RN
