Welcome to the 2025-2026 School Year

Welcome to My Classroom!

Hello! I’m thrilled to welcome you to another exciting school year at Dover High School, where I’ve had the privilege of teaching mathematics for the past thirty years. With over three decades of experience spanning middle school, high school, and college levels, I bring a deep passion for helping students discover the beauty and power of mathematics.

Throughout my career, I’ve taught a wide range of courses including Algebra 1, Algebra 2, Geometry, Pre-Calculus, Calculus, Math Foundations for Algebra 1 and 2, CCM Essential Mathematics, and CCM Intermediate Algebra. My educational journey has taken me from Union County College, where I earned my Associate’s degree, to Kean University for my Bachelor’s degree, and finally to Montclair University, where I completed my Master’s degree.

Beyond the classroom, I’m proud to serve as the advisor for Dover High School’s Chess Club, where students learn strategic thinking and problem-solving in a fun, collaborative environment. When I’m not teaching or coaching chess, you’ll find me enjoying crafts, practicing yoga, tending to my garden, or spending quality time with my family.

I’m looking forward to another rewarding school year filled with growth, discovery, and mathematical adventures. Whether you’re a student, parent, or colleague, I’m here to support your journey and help you succeed!
