The Ride
John is the author of the inspirational leadership book, “The Ride of Our Lives – Lessons on Life, Leadership, and Love”. The book tells the inspiring story about a family on a transformational journey as they bicycled across the USA.
This was 1983, no ubiquitous mobile phones, internet, email, Google, nor social media sites. The closest thing to connectivity was a payphone along a dusty road.
Through the journey they camped in a variety of places including farmer’s fields, state parks, behind churches and schools, town parks, fairgrounds, and even fraternity houses, John and Berti Gronski and their 15-month-old son Stephen experienced the best of Americans.
John shares the lessons learned on this adventure that made a lasting impact on his leadership philosophy over the following decades as a military officer, combat Veteran, and business leader.
