Mark Vignoles

CEO

Mark is Service West’s founder and fearless leader, who heeded the advice of his dad to chart his own course by founding the company in 1981. His success can be attributed to his ability to champion the company’s vision and culture both internally and externally, and to his interest in every facet of the organization. Mark’s been an installer, dispatcher, operations manager, and driver; if you can name it, he’s done it.  Now, as the company’s chief strategist and relationship manager, Mark is committed to building the organization for the next generation of talented leaders. He is a founding member of Facilities Services Network, an international best practices group that sets the standards in our industry. Always thoughtful and deliberate in his decisions, Mark married his elementary school sweetheart, Renee, with only 19 years between their first and second dates! He’s survived four recessions since founding Service West, testament to his resilience and strength, as evidenced by his black belt in Brazilian Jiu-Jitsu.

Vice President of Sales, Corporate Services

Benny Diaz Jr.

Vice President of Sales, Corporate Services

We like to say that Benny is “one in a million,” not only because he sold the company’s first million-dollar installation project, but because he has grown up with us, and we have grown with Benny. He began his Service West career in 1997 as a field installer and dispatcher, rising through the ranks with increasing responsibilities, leading to his role today as VP of sales, corporate services. He spearheaded adoption of our proprietary OrderWorks™ operating system, which gives our team a leg-up when it comes to order processing and tracking. When he’s not out in the field, you might find Benny by a quiet stream in Northern California, “fishing” for his next great idea.
