About DUNN Training
DUNN Training was an Atlanta-based leader in Microsoft technical training from 2002 to 2020, founded by me, Mark Dunn. For nearly two decades, I led a team delivering top-tier courses on .NET, JavaScript, and databases like SQL Server, working with clients like NASA and Coca-Cola.
In 2020, my cancer diagnosis paused that chapter. After three years and remission, I closed the company but couldn’t fully step away from teaching—it’s in my blood. Want the full story of my journey from Alabama to tech trainer? Read “My Story” here. Now, from Lake Lanier, Georgia, I offer occasional online classes in subjects I love:
- C# with Visual Studio
- ASP.NET Core MVC
- SQL Server for Developers
- JavaScript and HTML
Though I’m disabled and can’t teach full-time, I’d love to share my 30+ years of expertise with you or your team. Spread the word or reach out—I’m just a click away!

Mark Dunn - My Story
Early Life
I’m Mark Dunn—a tech educator, cancer survivor, and Lake Lanier retiree. Growing up in Blount County, Alabama, I faced tough times: losing my dad at 5, battling a stutter, and overcoming bullying. At 12, I learned resilience, performing Jerry Clower tributes to conquer my fears. That spark led me to speak at Microsoft conferences decades later. I graduated salutatorian in 1982, carrying scars but ready for more.
Family
At Samford University in 1985, I met Andrea—my red-haired, sci-fi-loving soulmate. We’ve shared 40 years, two amazing kids, and survived stage 3 cancers (hers breast, mine lymphoma). Now, we walk Lake Lanier trails and host “Count Me In,” a drummers’ supper club inspired by her wild gift of a drum kit.
Career Milestones
My 30-year tech journey started with self-taught coding—COBOL to C#. I built software for banks and radio stations, then founded DUNN Training, a Microsoft Gold Partner. As a 15-time MVP, I taught at Auburn University and trained folks across the U.S., earning Delta Million Miler status. It was a wild, rewarding ride.
Mentors
Great folks shaped me: Stan Solomon, my father-in-law; Dr. Dan Urry at UAB; and Carl Franklin, who taught me to lighten up. Their wisdom fuels my passion for teaching.
Retirement
Retiring at 57 wasn’t the plan, but remission made it right. I swapped 70-hour weeks for drumming, dog walks, and time with Andrea. I miss teaching, though—so I’m back part-time, online, from home. Let’s connect!
