Jim Topping became the first 100% vested retiree of the Sierra Pacific Employee Stock Ownership Plan (ESOP) and Larry Mirick, CEO and Dave Mochalski, VP of Sales presented him with his retirement check.

Jim was a consummate customer service rep — he was great on the phone, he understood the customers’ needs and he excelled at figuring out what SPEP could do to help each customer. People really appreciated his caring approach and his can do attitude.

Jim joined SPEP back in 2004 and over the course of the next 10 years he contributed greatly to Sierra Pacific’s growth. In retirement Jim plans on staying active, riding his bike, and traveling with his wife. We were lucky to have him while he was here and we thank him for all his contributions.

Sierra Pacific Engineering and Products is celebrating the 10th year anniversary of being a 100% employee-owned company. An employee stock ownership plan (ESOP) is an employee-owner program that provides a company's workforce with an ownership interest in the company.

As such, the employees at Sierra Pacific have a vested interest in the performance of the company. This includes developing, designing, prototyping, quoting, manufacturing, and delivering high quality products. At every step of the process, employees take to heart SPEP’s motto: “Quality and Service Taken Personally.” They have a stake in the outcome of the company’s performance and they understand that their hard work and dedication directly correlates with the company’s growth.

Being an ESOP company serves as a great motivator for employees to give their best performance and willingly subscribe to the concept that our customers are our most valuable resource. We strive to serve as we would want to be served.
