Psomas Welcomes Pfeiler and Associates

LOS ANGELES, Calif. (November 1, 2023) — Engineering consulting firm Psomas announced today it has acquired Yorba Linda based Pfeiler and Associates (Pfeiler), a well-respected Southern California Land Surveying firm with a rich 50-year history of serving clients. As part of this transition, Pfeiler will be rebranded as Pfeiler-Psomas. 

“Both firms share a unique history rooted in family-owned land survey businesses, underpinned by a commitment to delivering exceptional quality and service,” stated Psomas CEO Steve Margaroni. “Our shared cultures, values and deep expertise provide a rock-solid foundation upon which we will continue to build and succeed together.” 

With the addition of the Pfeiler team, Psomas will now have 770 professionals, serving clients across multiple regions including Arizona, California, Utah, and Washington. This acquisition further solidifies the company’s standing as an industry leader, supported by the 2023 California ENR ranking as the #1 firm in Survey & Mapping. 

“We have long held Psomas in high regard for their exceptional service, professionalism, and commitment to supporting their employees. I’m looking forward to the growth opportunities for our team and the expanded services we can offer our clients,” said Mark Pfeiler, President of Pfeiler and Associates.
