Mark W. Reidenbach

Project Manager
I knew I was going to be a Civil Engineer when I had to take EMCH 212 twice in college...

We have a lot of fun here at Gateway, but we also perform a large volume of work for our clients. I am Project Manager, Principal-in-Charge (PIC), supervisor and shareholder and wear many hats throughout the day. Primarily, I manage projects and assign tasks to resources for execution. I previously worked for Greenman-Pedersen, Inc. (GPI) in Scranton, PA, where I was a surveyor and civil engineer.

I enjoy spending time with my kids playing outside and exploring Hartwood Acres near our house.
