“Kerwyn was Awesome! I think it was the perfect fit for our Kids Fest 2025. Great that we could customize the length of shows and age range. As a Park and Rec provider of recreational programming, good, clean fun that is a fit for all ages is a necessity and sometimes hard to fine. Bongo Congo was exactly what we were looking for.”                            -Stephanie Juhl, Programing Event Coordinator, Watertown Park and Rec.  (7/15/2025)

"Kerwyn's infectious enthusiasm inspires my young musicians!  They love when Mr. K comes to music class!"                                                                                                                   -Erica Polak, elementary music teacher  (Spring 2025)

"Kerwyn is truly a standout substitute teacher in my music classroom and a favorite among the students. His engaging percussion activities keep every class focused, energized, and excited to learn. Students always look forward to seeing him, and I consistently hear positive feedback after his visits. Without a doubt, he is my preferred go-to sub whenever I’m out—I know the class is in excellent hands."                                                                                                  -Katie Franecki General Music Teacher.   Blakewood, K-5; E.W. Luther, K-2    South Milwaukee

"I know I'm leaving my class in very capable hands when Kerwyn subs for me! He offers exciting hands-on activities for the kids - they love playing all the instruments! He is easily able to adapt to different grade levels, and gives all the kids an enjoyable, memorable experience."                                                                                                                                              -Music teacher, Summit View Elementary  Waukesha  (Spring 2025)

​Kerwyn brings a type of energy and positivity to my classroom that goes unmatched.  From the moment students come to the room, they are fully engaged and excited--and when I return, they can't stop talking about how much fun they had and what they learned.  His dynamic approach keeps lessons lively and ensures every student feels involved.  He's my go-to substitute for creating a positive, dynamic, high-energy learning environment--his enthusiasm resonates with both staff and students, who genuinely appreciate and love his engaging approach.                                                                                                                                  -Tara Wirth, music teacher, Prairie Elementary, Waukesha  (Spring 2025)

"Kerwyn subbed for my music class (ages K through 8th grade). He used a variety of instruments to create a fun and interesting class that the students really enjoyed."                    -Jill Hollander, music teacher, Wauwatosa Montessori School  (Spring 2025)
