• About Mr. Lehman


    I grew up near Altoona, PA (Pittsburgh Steeler country) and graduated from Central High School in 1997.  I kept busy in HS by playing basketball, football, and running track.  My favorite subject was Math as I loved working with numbers and solving problems. However once I started college everything changed.   My Chem I and Chem II professors made a huge impact on my life by sparking my interest in chemistry.   Dr. Ewing would begin class every Monday morning by lighting multiple hydrogen-filled balloons to create loud, fiery explosions. (He called it an exothermic chemical alarm clock).  My Chem II professor pulled me aside during a fun three-hour chem lab and discussed an externship opportunity at a local paper mill.  I interviewed for the externship, landed the position, and spent the next three summers learning the science of paper making, paper coatings, and watermarking. 

    After graduating from IUP in 2002, I accepted a teaching position in the North Penn School District, where I taught Physical Science at Penndale MS and Chemistry/Biology at North Penn High School.  During the summers of 2003 - 2005, I taught chemistry at the Lower Merion High School Summer Academy.  In 2007, my future wife graduated from Pennsylvania College of Optometry.  We made a tough decision to leave Pennsylvania when she landed a coveted job at a private optometry practice in Richmond, VA.    After two years of living and working in VA, we decided to move back to PA to be closer to our families. (We were tired of battling the brutal Washington D.C. traffic every time we wanted to come back home to see our families!).   In 2010, I started teaching at Great Valley High School. GVHS is an awesome school where I am surrounded by awesome students, teachers, and administrators.

    After working at GVHS for five years, my wife and I decided that we wanted our children to receive their education in the GVSD.  So we sold our house in Conshohocken, packed up, and moved to Malvern!  We love living in Malvern and being part of this wonderful community.   Our two daughters Aviana and Madelyn attend Charlestown Elementary School (Go Bulldogs!). This is a very exciting time for our family as my wife Laura just became an Malvern Eye Doctor by opening up her own practice, VisualEyes Optique, in Charlestown Village. We have one family pet, a 14 year-old YorkiePoo, named Stewy.  Stewy likes to chase tennis balls, bark at squirrels, and sit by the kitchen cabinet until he receives a salmon-flavored treat from Wegmans (see above photo). Outside of school, I like to ride my bike on the local trails, go swimming, coach youth sports, attend church, watch comedies on TV, cheer for PSU football & Philadelphia sports teams, and golf at Pickering Valley CC.

    I look forward to having a great year!
