About Us

We represent manufacturers of professional Audio Visual products in the western united states.

Providing multiple services to our dealers, we take pride in our ability to help our installers and business owners sell the products we represent. Since Jim’s passing in 2022, his son Joe has taken over the company, and hopes to continue to honor his father’s legacy, and serve the territories with the level of expertise expected of Plus 4 Marketing.

Today

​

Since Jim's passing, Jim's wife and business partner Allison Mathews has been at the helm. The staff is committed to the company and dedicated to its customers. Each staff member has really brought his or her specific strength to the business. Plus Four is still known for its technical prowess, and the ability to assist customers without leaning on the specific brand to solve to issue.
