I was given an opportunity to hear Spencer Horn (Altium Leadership) speak at the Sioux Falls PMI Summit.  The way Spencer provided the information was phenomenal and helped me to see how I could better communicate with my teams. Spencer also helped me to determine my leadership style and how to coexist with other leadership styles.
I also took part in completing a ProScan questionnaire and discovered a few new things for my toolbox when working and communicating with others.  Spencer provides information in a manner that allows people to digest it and use it in their daily lives weather at work or home.
