I also participated in organized and school league baseball, basketball, and football, lettering in multiple sports in middle and high school, and playing in two baseball leagues most years.

On April 27th, 1996, while a senior at Sullivan North High School, I enlisted in the U.S. Army, officially becoming a Service Member on October 2nd, 1996. Early on I was recognized for my leadership and advanced through the ranks, spending 17 years, 2 months, and 11 days as a Noncommissioned Officer, and 11 years and 11 months as a Senior Noncommissioned Officer, holding numerous leadership positions, a Secret and subsequently a Top Secret/Secure Compartmented Information Clearance w/ Presidential level Yankee White access, retiring on October 31st, 2016 after 20 years and 29 days of faithful and honorable service.

I also served in Iraq on a Military Transition Team advising the Iraqi Army and Police Forces, in Afghanistan as a Platoon Sergeant with the 82nd Airborne Division, and as a Liaison to the Combined Joint Task Force-East during the 2012 “military surge.” Amongst my military and civilian awards and decorations are a Bronze Star, Defense Meritorious Service Medal, Meritorious Service Medal, Combat Action Badge, Parachutist Badge, Presidential Service Badge, Letters of Appreciation from multiple Presidents, and an appointment as a Kentucky Colonel.
