Speaking Engagements

John Gronski is an international and Fortune 500 speaker. He is much sought after to provide keynote addresses. John provides world-class seminars and training to private and public organizations. He coaches management teams and executives to grow better leaders across the United States.

General Gronski delivered a powerful, motivating, and memorable presentation that provided exceptional life lessons for leaders in all walks of life. His presentation at our association’s executive development workshop was a hit among our attendees. His presentation contained anecdotes that ranged from entertaining to emotional and were drawn from a variety of military and civilian experiences. Each story presented insight into valuable life lessons that enable leaders to become more effective in shaping the world around them. I highly recommend John Gronski for any audience that values life-long learning and seeks to optimize their impact in their personal and professional lives.

I admire Major General John GRONSKI as a great authority. He is not only a  leadership theorist but primarily a practitioner who has a vast experience in the area of military management. For this reason, I invited General GRONSKI to Poland in October 2021 to lecture at the Territorial Defense Forces Headquarters, Polish Military Academies, and civilian universities throughout Poland. During his lectures, he proved to be brilliant and inquisitive.


John Gronski provides excellent leadership seminars for student athletes and coaches.  His work at Lebanon Valley College has been invaluable for our teams.  I highly recommend him for any school or team looking to be challenged and sharpened in the areas of character and leadership development.

“Gen. Gronski’s presentation on leadership and resilience was full of vivid stories. The audience at NATO was in awe of his lively and captivating talk focused on achieving one’s purpose through resilience and perseverance”

Giedrimas Jeglinskas, Former Assistant Secretary General at NATO

John Gronski, MG (USA Ret.) runs a fantastic clinic on leadership and resilience. I’ve seen him deliver for groups as small as 10 and as large as 200. I cannot provide a higher recommendation for experienced, measured, genuine leadership lessons and insights than I can for John and Leader Grove. John is a class act!

“John Gronski was the best keynote speaker this PA School Bus Association convention has had to date, and I have not missed an annual convention in over 20 years. He engaged the audience and provided a powerful message on leadership. I could have listened to him tell stories for another two hours.”

PA School Bus Association June 2023

“Best we ever had!!! As our PSBA keynote speaker, John Gronski was inspirational, educational, and most importantly relevant to our business and us being leaders.”
