Nationwide design firm SmithGroupJJR has added mechanical and electrical engineering services at its Los Angeles, San Francisco and San Diego offices. Don Posson, the firm’s director of engineering services and sustainable design expert, has relocated from Washington D.C., to Los Angeles to lead the expansion.

The move supports the company’s strategic and operational initiatives and desire for steady growth, it explained.

“The specialized services and award-winning engineering solutions we’ve been known for nationally now will become more readily available to our California-based clients,” Posson said.
