     My name is Susan Marziale and I teach second grade at Warren Elementary. I started teaching in Baltimore County in 1998 and at Warren in 2002. I have an undergraduate degree in Elementary Education with a certification in Early Childhood and a Master's degree in Guidance and Counseling. I adore the families that I have had the opportunity to work with and look forward to working with many more. In my spare time I enjoy spending time with my two beautiful daughters and my husband, reading, and cheering for the Ravens!

            I thoroughly enjoy teaching here at Warren Elementary. I have been teaching here since 2008, when I started my teaching career with BCPS. I have a Bachelor’s Degree in Elementary Education and I am currently working towards a Master’s Degree in Leadership in Teaching Mathematics. I enjoy working with children of all ages, but right now I am fortunate enough to teach the 2nd graders. I love working with my students and watching them as they grow and learn. In my spare time I enjoy spending time with my husband and our yellow lab, Ellie. I also enjoy traveling to new or historical places, cooking, reading, and scrapbooking.
