As Wollborg Michelson Recruiting’s Chief Sales Officer, Matt Guerrero leads the Regional sales team and handles key accounts. Guerrero started his career at Wollborg Michelson Recruiting 9 years ago as the Sales Manager for the Sonoma territory and grew into the Branch Manager position overseeing Sonoma County and Marin County. He was then promoted to Regional Sales Manager in 2011 and is now responsible for the sales growth in multiple territories. His job includes researching hiring trends and making critical decisions on service offerings that will best serve clients and prospects.

Matt’s extraordinary work ethic has been a major contributor to the company’s success. Not surprisingly, he doesn’t have much time to reflect on how far they’ve come in the last 9 years; rather he focuses on what’s next and how to make the company continually better.

Matt believes that what sets Wollborg Michelson Recruiting apart is not a clever slogan, but obviously superior client service and top quality candidates. Attentive sales people provide the quickest response time with the most comprehensive answers in the industry. In this ever changing market he knows that clients and prospects are moving at the speed of light under tight deadlines and enormous pressure – they can’t wait to get the help they need.

In his spare time, he enjoys playing golf, snowboarding, water-skiing and spending his time with his wife and of two boys. He has also been active in his local community and on the board of his neighborhood association. He is also an Olympic Club member as well as a member of the Tiburon Corinthian Yacht Club.
