Working with Mark Zimmerman from On The Mark Coaching has been an absolute game-changer for our youngest son, Carter. As parents, we were looking for a coach who could help Carter develop not just his rugby skills, but also his mindset and overall growth as a player.

Mark’s passion for coaching and his genuine dedication to his clients stands out and Mark’s expertise in mindset coaching has had a profound impact on Carter’s journey. He has not only taught Carter how to set goals, but also provided him with the tools and strategies to overcome obstacles and reach his full potential on and off the field.

Mark’s guidance and mentorship have been instrumental in Carter’s success as a young rugby player. Under Mark’s coaching, Carter has not only improved his technical abilities but has also developed a strong mental resilience, enabling him to perform at his best even under pressure.

What sets Mark apart is his ability to connect with young athletes like Carter. He understands their unique challenges and motivates them to push beyond their limits. Mark’s coaching style is both supportive and empowering, creating a positive and nurturing environment for growth.

We wholeheartedly recommend Mark and On The Mark Coaching to any young rugby player seeking to take their game to the next level. If you want your child to have a coach who will inspire, challenge, and unlock their full potential, then Mark is the perfect fit. Carter’s transformation is a testament to Mark’s exceptional coaching expertise, and we are grateful to have him as a part of our son’s journey.

I was struggling with some of the boys in our u11 team and Mark kindly volunteered to hold a short discussion with our boys based around the importance of teamwork and attitude. The kids ended up going all the way to the Grand Final and the gratitude he’s encouraged I hope will take them one step further next year to being the premiers.

Mark presented to our IRAA players and all players were engaged and intrigued with Marks messages. Mark delivers related content to the players, which triggers many thoughts and actions. Many player were interested in more ongoing discussions with Mark after his presentation.

I recently seeked out help from Coach Zim and wish I had done it earlier. He had given me a completely different approach to change my mindset on and off the field. ZIm doesn’t just tell you what to do and send you on your way. He treats you like family always checking in wnating to know how the advice he gave you went. I try to speak to Zim weekly before my Rugby game. This gives me a relaxing reset to be able to think clearly for my game and even my week ahead.

Being supported by On the Mark Coaching has been a great experience. Just what I needed. Professional and personal. Our sessions have helped me gain new perspectives and I’m excited about the results. Highly recommended. Thank you OTM!


Mark is an incredible visionary, and has managed to help me extract the very best from my son, as well as a number of the players on my team.

He has a method of helping players setting achievable goals, and how to manage both success and failure, should either occur.

Good, solid values, and a wonderful manner. Nothing is too much effort, and I cannot recommend On The Mark coaching enough!
