Coder - Speaker - Microsoft MVP - Scuba Instructor

I’m a geek and I love sharing about the technologies that excite me. I do this through speaking at conferences, user groups, and other local events, organizing the Kansas City .NET User Group, providing technical training, writing on my blog, and sometimes on other outlets like Twitter, GitHub, Instagram, and YouTube. I’m honored to have my community involvement recognized by Microsoft with their MVP Award.

I don’t just geek out over software development. I also teach SCUBA diving as a PADI Open Water Scuba Instructor. If you are interested in discovering the underwater world through SCUBA I’d love to talk. You can learn more at Duane & Lisa's Diving Adventures.
