About Us

Firm Background

L&S Engineers began in 1955, when Ev Rice and Bob Luhn founded Rice and Luhn, a mechanical consulting engineering firm.

In 1986, two young engineers, Dick Luhn and Dale Shafer, joined leadership team, and Ev retired (it is rumored the next day!). This resulted in the engineering firm, Luhn Shafer.

In 1990, the firm added electrical engineering and Bob retired, and for a short period of time was known as Luhn Shafer Wanless. In 1991, firm was branded L&S Engineering Associates, a mechanical electrical and plumbing consulting engineering firm.

In 2001, Brad and Jessica joined the leadership, with Dick retiring in 2005 and Dale in 2017.

Our offices are located in the historic Commission Building in downtown Spokane.
