I am very excited to join Waterloo Elementary School for the 2016-2017 school year as the Leadership Intern. This is my second year as a Leadership Intern. I have been an educator for 20 years. During this time, I taught third grade, fifth grade, and sixth grade. I also was a Reading Specialist and a Reading Support Teacher for the Howard County School System. I earned my undergraduate degree from UMBC, my Master's degree from Loyola University and my Administration certificate from Johns Hopkins University. At home, I enjoy spending time with my two children and my husband. I look forward to partnering with the administrative team, our staff, students and families to cultivate a vibrant learning community.
