While attending school, Kevin arranged and taught percussion for the Nazareth Area High School and started their first indoor percussion ensemble that is still performing and is very successful to this day.

His guitar students at Norristown did a song writing project and several of them performed these songs as opening acts for the high school band and orchestra concerts.

The studio has been a great opportunity so far, but he is very excited to be directing the middle school band at Mountain Phoenix and has great anticipation for the coming school year.

He is a certified ASSI Level 1 snowboard instructor and taught snowboarding for 8 years, has worked for a YMCA providing swim lessons for 5 years, and highly values physical activity as part of a balanced lifestyle. Every person is responsible for taking care of their body and learning how to do that in a fun and safe environment is his biggest priority.

She discovered a wonderful loving community with a teaching philosophy that fit right in with her own pedagogy. Karen has more than 20 years experience teaching art to children of all ages. Much of that time was working with students in non-profit organizations. Karen believes art helps students to become life long lovers of learning.

Karen is a multimedia artist who periodically shows her art in the Denver metro area. As an artist, she is constantly learning new materials and styles for creating her art. Her undergraduate studies were in sculpture and modern dance. She graduated from SUNY Potsdam in New York State, spent a year studying at the Museum School of Fine Arts in Boston, and a semester abroad in England.
