Our Team

A self-taught businessman, Matt developed his skills across various lines of work before starting at Professional Business Systems in November of 1986, the year it was founded. Ten years later, Founder and President Marvin Gray Sr. retired, and Matt was named president. Under Matt’s leadership, PBS embarked upon becoming NWA’s premier service provider for copiers/printers. Today, PBS is more than just a copier company. The company creates solutions through office technologies while building relationships with clients, delivering on promises, and allowing customers to operate their businesses with the confidence their business solutions will work for them. Both of Matt’s two sons, Mitchell and Matthew, are in the family business. He enjoys spending time with his growing family including his wife, Marisha, and their three grandchildren (Mack, Mia, and McCall). Matt’s hobbies include boating, RV camping, golf, and duck hunting.

At an early age, Mitchell Mawby developed an entrepreneurial spirit and appreciation for hard work when he started a lawn business in high school. He is the son of President and CEO Matt Mawby and has been with Professional Business Systems for over a decade. However, he did not originally intend to follow in his father’s footsteps. He credits an early mentor, Chris Meyer – who was a PBS employee for 20 years before starting a church in North Carolina – for instilling in him a passion for the work. He says Chris encouraged him to join the family business and create a long-term vision for success, and for that he will be forever grateful to him. Mitchell is a graduate of the University of Arkansas, where he majored in business administration and marketing with a minor in economics. While attending college he worked as a credit analyst at Legacy National Bank. He says this opportunity gave him great perspective on business leadership and financial dealings. When he’s not working you can find Mitchell on the golf course, by a body of water, cheering on the Razorbacks or in the duck woods. Most of all, he enjoys spending time with his family – wife Maurie, son Mack, and daughter Mia.

While he was still in college, Matthew Mawby worked at Professional Business Systems in many departments, learning about the business from multiple perspectives – from truck deliveries to customer service. While he started with the PBS sales department after graduating, he looks forward to the opportunity to grow the business on the operations side. He is a graduate of the University of Arkansas, where he majored in small business/entrepreneurship with a minor in marketing. Matthew says he is grateful for the opportunity to work at PBS while attending college and credits the experience with making him passionate about how PBS continues to service the community of Northwest Arkansas. When he is not working, you will most likely find Matthew with his family, which includes his wife, Taylor and dog, Milo. He enjoys spending time on the golf course, hunting and relaxing by the pool or lake. He is also an avid fan of the Arkansas Razorbacks and Kansas City Chiefs.

In a role he describes as encompassing all things finance and administration, Jonathan appreciates that nothing is off the table when it comes to his job. Focusing on ways to grow the company and presenting financials in a leadership meeting are always top of mind. And, since joining the PBS team in January 2024, he’s become accustomed to finding tasks such as printing envelopes and grabbing the mail on his workday to-do list, too. After 12 years of working with a company of about 82,000 employees, Jonathan experienced a big change in the workplace dynamics of a smaller-sized office. The family atmosphere at PBS quickly revealed itself and caught his attention. Plus, he discovered the fast-paced environment he found here – one that leaves him with a feeling that every day feels like something new – was something he loved. When he’s not going full speed in the office, Jonathan can be found golfing, running, hunting, and reading. He’s also a fan of hanging out with his family and chasing his kids. He and his wife, Megan, have three sons – W.O., Walter, and Hughes – and a dog named Wallace.
