A Message from the Principal

Dear Lake-Lehman Junior/Senior High School Students, Parents, and Guardians,

Knight logo

I am honored to introduce myself as the new principal of Lake-Lehman Junior/Senior High School! I am thrilled to join such a dedicated staff and community that make Lake-Lehman Junior/Senior High School a great place for students to want to come to school.

Allow me to share a bit about myself. My name is Matt Nonnenberg, and I bring with me fourteen years of experience in education, with a strong passion for academic excellence by meeting students where they are.  

My educational journey includes a bachelor of arts in education in technology education from both West Chester University and Millersville University, a master of science in educational leadership from Wilkes University, and a letter of eligibility degree from Delaware Valley University. Throughout my career, I have had the privilege of working in various educational roles, which include serving as a middle school technology education teacher, a high school graphic arts teacher, an assistant principal at Lake-Lehman JSHS, and an elementary principal at Ross Elementary School.  Each of these experiences have provided me with valuable insights into understanding what it takes to make students the best possible version of themselves.

I firmly believe that open communication and collaboration are essential to student success. I always encourage the concept that Together Everyone Achieves More (TEAM), and I encourage parents and guardians to actively engage in their child’s education and be a part of our team. Throughout the school year, you can expect regular updates on important events, academic achievements, and extracurricular through our KnightLife newspaper, All Calls, and updates on our school website. I also encourage you to attend school activities and functions as we cheer on our Knights!

At Lake-Lehman Junior/Senior High School, my goal is to build upon and continue the existing culture of excellence and achievement. Simply put, I will work as hard as I can to make all students want to come to school! I believe in meeting every student where they are and seeking out their interests with a direct focus on career-based success. In this day and age, I foresee the importance of critical needs of job shadowing so students truly know what they want to become and financial literacy so they know how to get there.    

I am truly excited to start this year with all of you and look forward to getting to know each and every one of our students and families. Please feel free to reach out to me at (570) 255-2797 or via email if you have any questions or concerns. On a final note, my ultimate goal is to make good people.  Always remember: good people will do great things!

Have a wonderful, relaxing summer, and I look forward to seeing everyone in the fall. 

Go Knights!
