The People on the Floor

A police officer, a pastor and a business analyst coach here. Several have been on this floor since the doors opened in 2018.

Tanya Matzdorf

Coach & General Manager

Tanya Matzdorf

After being pulled into a CrossFit class by now owner David Bolland back in 2017, Tanya was hooked. Tanya is the first line of contact for CrossFit Diligence, and rightfully so. She puts people at ease when trying something that may be scary. She’s a great representation of the community first mindset we have and try to instill as much as possible. When Tanya isn’t in the gym, she is following her son’s kart racing throughout the greater Midwest!

Tom Matzdorf

Head Coach

Tom Matzdorf

After joining CrossFit Eastern Ridge in August of 2013, Tom quickly fell in love with community based fitness. After a year as an athlete, Tom wanted to share his passion for CrossFit and became a coach. Tom has been with CrossFit Diligence since its inception in 2018. His biggest joy is working with people who think they can’t and sharing in their joy of accomplishing goals in workouts and personal lives. When Tom is not at the gym, he loves being outside applying his fitness or snapping his next favorite photo.

Jenna Koebert

Coach

Jenna Koebert

Jenna started her CrossFit journey back in 2013 and started coaching in 2017. She loves everything that CrossFit has to offer people when it comes to functional fitness, but most importantly the community! She loves to help people grow in their fitness goals, as well as supporting them in and out of the gym. When she’s not in the gym she works full time as a third shift police officer. Beyond that she spends time with her son, husband and dog. They love watching races and doing anything outside together.

Aaron Martell

Coach

Aaron Martell

Aaron was one of the original members of CrossFit Eastern Ridge. It didn’t take long for him to get hooked and have a great desire to grow with CrossFit. Aaron has always been a part of coaching; right out of college he helped coach football in St. Paul, then when his own children came along, he coached soccer, football and baseball. He has been a coach with CrossFit Diligence since 2018. Aaron enjoys time with his wife and two children, is an avid Wisconsin sports fan, and enjoys long walks in the woods with his family and dog Reesey. His real job is Lead Pastor at New Life Community Church in Plymouth, and he is also the chaplain of our local Faith Rx chapter.

Tracy Amweg

Coach

Tracy Amweg

Tracy has been passionate about CrossFit since 2014. After discovering the sport while searching for a way to stay active and overcome recurring knee pain, she found that functional strength training transformed both her fitness and her outlook. Inspired by her experience, she earned coaching certifications to help others improve their health and become part of the CrossFit community in the Sheboygan area. Outside the gym, Tracy enjoys spending time with her husband and family, traveling, trying new restaurants, and works as a Business Analyst at Amerequip.

Liz Strahl

Coach

Liz Strahl

Liz joined CrossFit Diligence in 2022, when she was pregnant with her first of two children. Liz loved the thrill of learning new skills in the gym and applying them to her everyday physical job. She understands how CrossFit works from scaling for pregnancies and making small progress post-partum. When not at the gym, Liz enjoys spending time with her husband Tom, two kids and dog. You will often find her meal prepping for the week and willing to share her ideas on the basics of nutrition. She’s excited to share her journey and motherhood experience with anyone.

David Bolland

Coach & Owner

David Bolland

Dave was assigned the CrossFit Harvard Business School case in 2016 when he attended the HBS-YPO Program. Dave returned from the program and immediately joined CrossFit Eastern Ridge, not knowing he would one day partner to help create a sister gym in 2018, initially named CrossFit Western Ridge, which became CrossFit Diligence in 2022. Today, Dave enjoys being an early morning athlete as well as an occasional coach. His main motivation is to build a great community culture led by a servant leadership team who strive to role model our motto of ‘do what you can’t’. We’re here to give others the life changing experience we’re all enjoying today.
