Trusted Officials

The Minnesota Youth Athletic Services (MYAS) has been Minnesota's Home for Youth Sports since 1991.  Our organization is based on an educational foundation and we have been training basketball officials and baseball umpires for over 30 years.

With over 12,000 basketball games and 8,000 baseball games each and every year, we look to provide the best training possible to those who want to learn how to become an official.

We have Assignors on deck just waiting to schedule YOU for your first game of the season.

Tony Schrepfer

MYAS Director of Officials

Sports and athletics have been a part of my life for as long as I can remember. I raced competitive BMX for about six years and then got back into playing team sports. When I finally realized that my best playing days were behind me, I found my passion for becoming an official.  I still wanted to be a part of the game and officiating gave me that avenue.  I’ve been calling games for over 35 years now and am still currently active officiating in the sports of Basketball, Baseball, and Fast Pitch.

I accepted the duties and responsibilities of the MYAS Director of Officials with the ultimate goal of infusing excitement in becoming an official. Just as being a player has it’s certain demands, executing the role of an official brings with it its own challenges and rewards. With on-court training, proper mechanics and rules knowledge any official can go as far as they would like in this profession.

When I envision the future of officiating at the MYAS, I see a new generation of officials that not only want to give back to the game and still be an important part of it but also hone the craft of officiating and ascend the ranks.  I'm very passionate about being an official and I want to change the perception of what being an official looks like and what it feels like.  Right now, is a great time to start your officiating career and with our help here at the MYAS we'll help you achieve your goals!

Remember… I'm one of you. Officials working on behalf of officials!

Carolyn Derksen

Assistant Director of Officiating/Administration

Hello! My name is Carolyn Derksen. I was born and raised in Maple Grove, MN. I graduated from Maple Grove Senior High and the University of Wisconsin - River Falls, earning a Bachelor of Arts degree in Communications Studies. I received my Master’s degree in Organizational Leadership from Gonzaga University. I enjoy spending time with my family and friends and being an aunt to my niece Elle and my nephews Wendell and Brooks. I am a huge sports fan, especially basketball and football.  My officiating journey began when I was a junior in college working in the intramural program at UW-River Falls. I have always loved the game of basketball and I knew I wanted to be around the game in some way after my playing days were over. During my senior year of college, I served as a student manager for the women’s basketball team. My intention for serving in the role of student manager was to help me ease into coaching. After I graduated from college, a family friend who was an official informed me of a shortage of officials and encouraged me to consider giving it a try.  I planned to officiate for one year and then move into coaching. After completing my first year of officiating, I was hooked and have never looked back. I am currently officiating high school and women’s college basketball, and high school football. I am so excited and ready to get to work as the MYAS Assistant Director of Officiating/ Administration.  I feel that my enthusiasm and passion for officiating will benefit me in this role. I want to get people excited about becoming an official and learn the rewarding benefits that come along with it. Many people do not consider officiating for a variety of reasons. But without officials, there are no games. I want to change people's negative perceptions of becoming an official and relay the fun and good friendships that can be built along the way. The MYAS intends to establish relationships with the different youth athletic associations in Minnesota by providing the best services that we can for youth sports officials. I am extremely passionate about guiding youth officials on their journey, which will look different for just about anyone that enters this avocation. Every official will have different goals and aspirations in their officiating career. We want to lay the foundation by providing our officials with the proper training and education. Those training and continuing education opportunities include developing communication skills, rules of the game, and proper mechanics, that will get officials prepared to hit the courts and the fields. The MYAS Director of Officiating and I want to be able to provide continuous education to new and current officials as a way for them to improve their craft.  Our training will include in-person/virtual/online formats as a resource for officials to utilize. Our main goal is to provide the tools for excellence along with a rewarding and enjoyable experience.
