Founder & President
Gary Rensch saw the beginning of an Apple revolution far earlier than most.
After earning his degree in English, Gary found work in the printing industry as a copy editor and as a page-layout apprentice right after the Mac was invented. It was the stone age of computers and digital pre-press. The software was amazing but rudimentary by today's standards.
In 1994 after gaining experience working at Computer Solutions, Gary started Electronic Publishing Services (EPS) a home-based business focused on sales and service for professionals using Macs. EPS later became Mac Pros where he built an expert team.
Gary's passions include travel, construction, and producing tear-jearking family videos.
Allen Newman's first computer experience was learning BASIC programming on a TRS-80 Model I in sixth grade, but that was before he tried MacPaint on the original Apple Macintosh — that was a magic moment in 1984! Feeling empowered, Allen jumped right into graphic design, creating his junior high school yearbook cover, his high school choir department logo, and writing and illustrating articles for his local Apple user group's newsletter. Before his frequent visits to his local computer store inspired his career choice, Allen's Mac skills shaped his college years, where he was design editor and unofficial Mac I.T. guy of his college newspaper and also learned digital sound design for theatre.
Allen has over 20 years' retail experience, starting in 1997 as a salesperson at Computer Solutions, and as office manager at Mac Pros since its founding in 2004. As store manager, Allen helps our sales and service teams improve customer service, handles our day-to-day relationships with Apple and other vendors, orders products and supplies, manages our point-of-sale software, website, and social media, schedules staff, does our payroll, and keeps our books. Allen also helped update our building facade and logo designs. When he's not at work, Allen enjoys using a Mac mini as a home media center.
Service Manager, Chief Apple Certified Technician
Christopher got his start on Apple technology while working for Gary Rensch, at Electronic Publishing Services (EPS) of Sioux Falls back in the late 1990s. Christopher took excellent care of his digital prepress clients during those early years, until the urge to break out on his own and take on greater challenges took him to the Twin Cities metropolitan area where he started MacWorks, a small Apple-focused IT service company and web development shop. Christopher provided fast and reliable Apple-related services to his many small business customers.
Christopher started programming in BASIC when he was just eleven years old, and later immersed himself in the study and support of internet technologies when the World Wide Web took its first baby steps in the 1990s. Over the years, he has built a number of dynamic, data-driven web sites and web applications. His favorite web language is PHP. His favorite creative hobbies include: digital photography, fresh water aquariums, and gardening.
Christopher continues to ensure quality service at Mac Pros by building and refining better systems that ensure high customer satisfaction, accurate repair quotes, fast turn-around times, and more.

Alec began his Apple career in 2015 working as a service tech for “Simply Mac”. Following their emminent demise, Alec was forced to wander the streets of Sioux Falls offering low-cost iPhone and Mac repairs to passers-by.
We realized we had to help so we put him to work which satiated his deep desire to repair Apple products accurately and quickly. In exchange, we gave him a livable wage and all the coffee he can safely consume.
