Scott Futrell began working at RPM in January of 2010 as a salesperson. In 2011, Scott and his wife Margaret, partnering with friends, seized the opportunity to purchase the company. Both took on active roles in the day-to-day operations, with Scott overseeing the sales and technical sides and Margaret handling the financial and office administration.

In January 2019, the Futrells purchased the company outright, found a new space for the office and warehouse in McKinney, began renovations, and in July, 2019, moved to their current location at 1404 N. McDonald St., Suite B. With Margaret as CFO and Scott as COO, they now lead a team of 23 employees and are growing in a faith-based, customer-centered, employee-friendly environment.
