SmithGroupJJR, an integrated design firm, has begun offering mechanical and electrical engineering services in-house at its San Diego, Los Angeles and San Francisco offices.

Don Posson, director of engineering services and a sustainable design specialist, has moved from SmithGroup’s Washington, D.C. offices to Los Angeles to lead the expansion.

“By adding Don’s expertise to our West Coast leadership team and expanding our service offerings to include engineering talent in California, we’re stating loud and clear that we’re becoming increasingly multi-disciplined and fully integrated,” said SmithGroup Managing Partner Troy Thompson.
