Very informative and interesting. The stories Mr. Gronski had were incredible and enlightening.

John’s story and enthusiastic portrayal is great. I recommend him to anyone.

General Gronski’s presentation skills are highly polished. This was fun!

 I thought his presentation is worthy of a second or third watching. M.P. AHEC Director

John’s commanding presence and knowledge of the subject matter coupled with real-life stories of leadership and character gave the presentation an authenticity that showed John’s experience as a high-ranking military officer and CEO. 

The leadership webinar conducted by Mr Gronski was superb, perhaps my favorite of all the AHEC webinars so far. He was informative and highly engaging, and I learned some really interesting lessons from his talk. And I also appreciate the fact that he answered my question personally via email. A huge credit to AHEC for organizing these webinars! They are a great way to fill time during this unusual period in the nation’s history.

R.N., Hummelstown, PA

You consummately engaged participants in activities by way of PPT and chat. Moreover, you conveyed a highly-effective message with confidence, competence, and clarity–which is indicative of your military background, leadership skills, and achievements.

I watched MG (R) John Gronski’s talk last week and found it very valuable for its leadership insights, made very practical and usable by leaders across the private, public, and civil-society sectors. For example, his definition of “Purpose” as not only the “what” but also the “why” in terms of motivating his Brigade team to defeat the insurgents in Ramadi, Iraq to protect our homeland made the idea of “Purpose” much clearer for me. 


John’s presentation and delivery kept our audience engaged and interested. His real-life stories solidify points that everyone can use in their own daily interactions at work and home. We thoroughly enjoyed having him as a speaker! R. W. Iron Mountain

Our Project Victory session with Gen. Gronski was inspiring and insightful. He offered leadership guidance drawing from his personal experience and made the conversation interactive by inviting our group to share their best practices as well.

John Gronski’s leadership session was such an insightful and engaging one. Loved the way John asked introspective questions, and built upon the answers provided by the attendees. Looking forward to reading John’s book.
