About Us

Computer Showcase was founded in 1990 by Mark Whisenhunt as a computer reseller. His brother, Eric, joined the company two years later. During the past three decades, the business has evolved into a technology consulting firm providing comprehensive solutions for small and mid-sized companies. The array of services offered spans the entire technology lifecycle. Starting with strategic planning and budgeting. Then implementation and integration. And finally, ongoing support and maintenance. As technology advances, the lifecycle begins anew.

And while technology-based products and services may have evolved over the years, the company’s core philosophy remains the same – do what’s best for each customer based on their individual circumstances. There is no “one solution fits all” mentality. Comprehensive solutions are developed based on an organization’s size, industry, budget, risk tolerance, and preferences of the business owner.
