Shanna Lonsberry


I became an IAABO official in 2014 after spending 10 years coaching girls basketball.  My career started in the IAABO Junior League and has extended to the high school, junior college and D-3 level.  

Growing up with basketball around me from a young age, I never thought officiating would become a passion of mine.  IAABO 173 has led me to many opportunities that have enriched my life.  From reffing Special Olympics, volunteering at our Coaches vs. Cancer tournament, graduating from the Officials Development Program to becoming a board member, this organization has grown myself personally and professionally!  I look forward to serving on the board and extending our IAABO family in the upcoming years!

Dominic Blesener


Dominic began officiating lower level basketball while still in High School in Minnesota in 1996.
After moving to St. Louis in 2006 he joined IAABO in 2007 and began working High School games.  Dominic was elected as a member of the Board in 2011 and has served as Chairman of the
Board during his entire tenure.  With a passion for not only improving himself, but also others within the
organization, Dominic was part of the of first graduating class of the IAABO Officials Development Program (ODP) and has served as a mentor to other officials since his graduation of the program in 2011.  Dominic has a strong belief in giving back to both the game and the local community and continually donates time and money to IAABO sponsored events such as Special Olympics, American Cancer Society, and the IAABO Scholarship Golf Outing.  Recent successes for Dominic include working his first District Championship game in 2010-11 season, began working for the AMC, SLIAC, and GRAC conferences for NCAA Women’s Basketball during the 2012-13 season, and worked his first ever Missouri Sectional game during the 2013-14 season.

Mike Moehlenkamp


After coaching my sons in CYC basketball I began officiating CYC games about 20 years ago. I was encouraged to start officiating lower level high school ball. I joined IAABO 4 years ago and have enjoyed the experiences I had going through the ODP Program where I’ve learned a lot. I have been involved to the golf tournament and coaches vs cancer. I’m also proud of the fact that my oldest son Matt is also an IAABO official.

Chris O'Dell


I started officiating in 2001 and joined IAABO in 2005. I've had the pleasure of working at the college level on both the men's and women's side. As a former player, I felt that officiating was a great way for me to stay close to the game I love. Getting selected to work district playoffs, district championships, sectional games and Missouri vs Illinois HS border war games has been a highlight but my favorite games every year are at the Special Olympics. Also in the past 2 years I've had the honor of working varsity level basketball with my Son, Collin.  I believe that IAABO 173 has a fantastic structured program for officials who want to get better. Plus, the generosity of IAABO officials is second to none.
