Wojnarowski said “this craft transformed my life. I understand the commitment required in my role and it’s an investment that I’m not longer driven to make.

I am hopeful that I can bring value in a lot of areas to our basketball program and open doors for our young men’s futures in ways both professionally and personally.”
