"Influential Mentor"

"Hello to my very first and most influential mentor and suppo (Supply Officer) trainer!! Great to hear from you Dave. “If your not teaching, your not learning” - you’ve always been a natural teacher and superb trainer!"

Rear Admiral Peter Stamatopoulos, USN

Director of Logistics 

Toastmasters and Instructor

"I have had the pleasure of knowing David Larson since about 2007. I first became acquainted with David when he served as President of his Toastmasters Club at the Navy Depot in Mechanicsburg, PA. He and I became additionally acquainted because he was an adjunct faculty member at Central Penn College in Summerdale, Pennsylvania, where I served as Strategic Advisor to the President and as an adjunct faculty member. I was impressed by David’s communication and leadership skills as well his outgoing, caring personality that fostered trust and built good relationships with others. David’s leadership experience in the US Navy as a Commander coupled with his skills in communication were assets I tapped in my own training company. David assisted me as an instructor in some of the communication workshops that we conducted for clients.

I have the utmost regard for David not only for his skills and talents but also as he is a man of principle and character. It is my pleasure to highly recommend David A. Larson, Sr."
