        FROM GUY GREGG,  Director of Bands - Oak Creek High School 
 "We were extremely fortunate to be able to host Jack Grassel and Jill Jensen as guest artists for our High School Jazz Ensemble concert.  
Jack and Jill are consummate professionals who brought an incredible breadth of experience, knowledge, musicality and kindness to our 
 our classroom. They related to students and told incredible stories of their own musical journeys. They came to rehearslas and collaborated
seamlessly while performing with our students.  Jill offered sensitive musicality and advice that students do not get from anyone other than 
a passionate professional. Jack's virtuosity exposed elements unknown to our students and opened their eyes to so many future possibilities. 
Above all, Jack and Jill are class acts and were shining role models for our students on how to treat each other and our music".
