OSA Professional Staff

Bob Franzese, Co-owner and General Manager

Bob's love for the game of basketball developed during his junior high school, high school and college days, when he was heavily involved at Omaha-area YMCA's as a scorekeeper, referee and coach.  In his early 20's, Bob was a varsity assistant coach at Lewis Central (Iowa) High School, and then took a job as the Athletic Director at Omaha's Jewish Community Center (JCC).  While at the JCC, Bob grew the basketball program from 120 participants to over 450, and he added soccer, flag football and lacrosse to the athletic department's program offerings.  Bob's ability to grow sports programming continued after he co-founded the Omaha Sports Academy (OSA) in spring 2008.  Since that time, he has built the largest select basketball club program in Omaha (40 winter teams and 35 summer teams), and has grown the No Frills Predator League from 100 teams to over 550.  Bob's coaching style is a demanding one, yet his passion for the game and love for his players shines through.  His players are among the most-prepared for the “next level”, whether that is high school or college.  A “student of the game,” Bob constantly educates himself by frequenting high school and college practices and the Oklahoma City Thunder training camp.


Rachel Blum, Assistant General Manager

Rachel began work at OSA in July 2009, and is currently the Assistant General Manager.  She is involved in the administrative aspects of all OSA programming and day to day operations.  She is responsible for scheduling all league and tournament games and oversees the implementation of these games, including staffing, venue rentals, and general game day operations.

Rachel also oversees the OSA registration process, from the marketing of every program and making sure all individual and team registrations are entered correctly to customer service and communications regarding these programs.  She works directly with our Select basketball staff in ensuring an efficient and organized registration process each fall and summer season and works with all league and team coaches in order to best meet each team's individual scheduling needs.

When asked about what she likes most about her job with OSA, she will be quick to tell you about her love for the game-day atmosphere!  “Our technological advances have allowed us to efficiently and effectively keep up with the latest trends in youth sports, and seeing it all come to fruition at every tip-off is quite the reward!”

Rachel has a BS Education degree from the University of Kansas, with a minor in English.  She is about as big a Jayhawk fan as they come, and you can be assured that if you pass by her wearing any Kansas attire, she will give you a “Rock Chalk” and will expect a “Jayhawk” in return!
