About the instructors:

Major General John L. Gronski (US Army, Retired)

When John Gronski graduated from the US Army’s elite Ranger School in 1990, he was 34 years old, and was the oldest student in his class to make it through the rigorous course. He still remembers a Ranger Non-Commissioned Officer offering this advice at the end of the course, “Now that you have earned that Ranger tab, you have to prove you deserve it every single day.” John has been trying to prove himself every day since and believes that self-discipline is the key to success. John believes one must look for opportunities to leave one’s comfort zone and seek challenges in order to develop resiliency. 

One of the biggest challenges of John’s life was commanding 5,000 Soldiers and Marines in Ramadi, Iraq in 2005 and 2006, At that time Ramadi was known as the most dangerous place on earth. It was there that John saw exactly how important every member of the team was. When the wolf is at the door there is no room for arrogance and leaders must have the ability to communicate and instill “purpose” into the team. 

John’s leadership philosophy is based on character, competence, and resilience. Even though John has over 40 years of leadership experience in trying conditions in both the military and civilian sectors, John is still on a journey to become an even stronger leader. John is highly respected for his operational leadership experience and is a leadership trainer popular with law enforcement and civilian executives alike due to his “muddy boots” style of getting out with those he leads and setting the example.

Major General John Gronski (USA, Ret.) served 40 years in the United States Army both on active duty and in the Pennsylvania National Guard. John has commanded infantry units at every level from a 140 Soldier company to a 15,000 Soldier division. John is a decorated combat Veteran and has served overseas four times during his career. He attended numerous Army schools to include the US Army War College, Infantry Officer Advanced Course, Ranger School, and Airborne School. John has a Master of Strategic Studies from the US Army War College and an MBA from Penn State. He is the founder and CEO of Leader Grove, LLC, a leadership consulting firm. John is an experienced leadership trainer, international speaker, executive coach, and author of two books, “The Ride of Our Lives” and “Iron-Sharpened Leadership”. 

John and his wife Berti have been married for over 41 years. They have two sons. Stephen served in the United States Marine Corps and works with the reservation maintenance department at Ft. Indiantown Gap. Timothy served in the United States Army and had combat deployments to Iraq and Afghanistan. He is a Pennsylvania State Trooper. They are also blessed with grandson Kevin and granddaughter Emma.

Christopher Kaag

You may hear Chris Kaag’s booming voice before you see him roll around the corner to greet you with a huge smile and an even bigger handshake. Like many influencers in the community, Chris Kaag wears numerous hats as the founder and Executive Director of the IM ABLE Foundation, founder of Corps Fitness, adaptive athlete, public speaker, and relentless advocate for the adaptive community. Shortly after graduating High School, Kaag served his country in the United States Marine Corps for almost five years. He still remembers the words of his Drill Instructor, “Don’t quit on me, Kaag” which would serve as a beacon of hope and reassurance in the upcoming years. 

At the age of 21 and in the prime of his military career, Kaag was diagnosed with adrenomyeloneuropathy, a rare degenerative condition affecting the myelin sheath of his nerve cells and was discharged from the Marine Corps. He began to walk with a cane, then two canes. With new direction and a “don’t quit on me” attitude, Kaag earned a business degree from Penn State Berks and began using his military-style fitness regimen to train small and large groups. These training sessions and Kaag’s passion for improving the quality of life for those around him through physical fitness, evolved into Corps Fitness, headquartered in Wyomissing, Pennsylvania. Meanwhile, his condition continued to worsen, and he soon transitioned to a wheelchair. Kaag persisted with strength and resiliency and began competing in races and raising funds for medical research which gave way to the new-found pursuit to assist other veterans and individuals with disabilities. 

In 2007, he launched the IM ABLE Foundation, with the mission to remove obstacles that prevent people with disabilities from being physically active by providing grants, resources, fitness opportunities and motivation. His motto was simply, “Get Up and Move!”. He has developed programs like IM FIT, a free fitness class for all adaptive children and young adults to practice the fundamentals of exercise together in a supportive and motivational environment, Operation Lead From the Front, a mentorship program which matches adaptive athletes with veterans in a relationship fostered around physical fitness and fun, and Rally Point, geared around his passion for the trails, which joins the adaptive and able-bodied community on various level bike rides through the Berks county trails and beyond. The IM ABLE Foundation has also awarded hundreds of equipment grants to motivated and deserving individuals in the adaptive community. 

He has been able to accomplish great things with the support of his resilient and ever-supportive wife and fellow-trainer, Gretchen Kaag. Their rambunctious and lovable son, Carter, is a testament to the Kaag culture. Chris Kaag is an inspiration to everyone, able-bodied and adaptive, that he encounters, and he encourages them to celebrate the abilities they have, rather than focus on those they don’t. Chris, his family, his team, and his community believe that an active lifestyle is achievable for all, regardless of their abilities.
