About Us

Achieving Engineering Excellence

Meta’s goal is to treat each and every assignment as an opportunity to showcase the abilities of the entire Team, and Our Company, and the Client.

Who We Are

A team committed to client satisfaction & success

Meta Engineers P.C. was founded in 1979 by Mr. Julius L. Szalay, P.E. with a team of five people. We quickly grew to a ten person firm. In 1980, Paul MacDonald, P.E. (PSU AE 77) and Donald Hennings, P.E. (Cal Poly ME ’75) were brought on board from Syska and Hennessy. In 1983, Kerry Frantz, P.E. (PSU AE ’81) joined the team. Kerry also worked for Syska and Hennessy prior to Meta Engineers, P.C. In 1985, Donna Castelli, P.E. (PSU AE ’85) was hired as a graduate directly from Penn State.

 In 1999, Mr. Julius L. Szalay P.E. retired and turned the reigns of the firm over to Paul, Donna, Don and Kerry.

Today, Meta Engineers, P.C. is lead by Donna and Paul. As principals of the Firm, Donna and Paul are supported by young, talented and dedicated Engineering Team Leaders.
