Penn Cambria School District has collaborated the last 4 years with the Keller Engineer’s team to complete a multi-phased paving and drainage project on our HS campus. I have personally worked with Adam Long, Brian Smith and Shawn Ritchey throughout the entire project and they made Penn Cambria feel like we were their only client.
