Diamond6 was founded by U.S. Army Colonel (Ret.), Dr. Jeffrey McCausland.

Inspired by his diverse leadership experiences, challenges and great leaders he has met over the years. Dr. McCausland has brought together a prestigious group of faculty members located across the country to teach all aspects of leadership and leadership development. 

We have been running leadership development workshops since 2004. Diamond6 Leadership & Strategy, LLC was established in 2010 to continue the rapid growth and success of our work.


What does Diamond6 stand for?

Diamond6 was Jeff’s radio call sign during the first Gulf War. As commander of the 3rd battalion, 17th Field Artillery, a unit of the 2nd Armored Calvary Regiment, McCausland led 750 soldiers into Iraq in the spearhead of the VII Corps attack.

Jeff believes that leading soldiers in combat was the most extraordinary and truly unforgettable leadership experience he has ever had. He named the business Diamond6 as a way to connect back to that experience, remember all the brave soldiers he worked with, and to inform and inspire his work in leadership development.

On the day of their return Jeff decided that his battalion would make a special entrance. Rather than have the bus pull into the barracks, he had his men step off the bus outside the gate. From there they marched in together to be greeted by their waiting families. It was a memorable day for everyone!
