Welcome to Thunder Hill Elementary! I am very excited to serve as principal at Thunder Hill. I am committed to ensuring that every single student within the Thunder Hill community is provided with amazing opportunities to learn, grow, and succeed. As I begin my 24th year in Howard County, I feel very fortunate to be a member of such a dedicated staff and active school community. I am looking forward to working with you as a partner in education to ensure your child's academic success. Along with committed staff, I will work hard to continue the legacy of success established at Thunder Hill by creating and maintaining strong relationships with parents, students, staff, and community partners. When I am not working with the stakeholders at Thunder Hill Elementary, I am most likely spending time with my husband and my two sons who attend Howard County public schools. As a family, we enjoy playing sports, taking trips to the beach, and exploring the many areas of Howard County. In the Thunder Hill community, we take pride in providing a safe, nurturing, and welcoming environment while encouraging our students to reach their full academic potential. In addition to academic growth, we want to ensure our students grow in the arts. We also want our students to develop social and physical fitness skills. Thunder Hill Elementary School provides an education where children continually learn and grow while experiencing the world around them. I know we will have a wonderful year together. I'm looking forward to getting to know our families. Please don't hesitate to contact me throughout the school year if I can be of assistance to your child or family in any way. I am looking forward to a great school year!

Hello Thunderbirds! I am excited to join the Thunder Hill family. I served as an Administrative Intern at Veterans Elementary School this past year. Prior to this, I spent eight years at Talbott Springs Elementary School, where my roles included fifth-grade teacher, GT Resource Teacher, and second-grade ITL. Beyond my teaching experience, I have over 20 years of leadership, management, and staff development experience. I earned my Associates Degree from Howard Community College, a Bachelors of History from Towson University, a Masters in the Art of Teaching from Towson University, and Postgraduate Certification in Administration from McDaniel University. I am deeply committed to fostering inclusive environments, and have demonstrated this with my involvement in the HCPSS LGBTQIA+ Advisory Committee and serving as Rainbow Representative at TSES and VES. I was fortunate to be recognized as a Baltimore Orioles Birdland Community Hero for his efforts in promoting a safe and accepting learning environment.
