Jonathan took up the clarinet as an adult, and thus a complicated relationship ensued. He played for many summers with the Mt. Washington Valley Band, and served as treasurer. In the early days of Mountain Top Music Center, he joined the nascent orchestra, becoming a regular in both orchestra and group ensembles performing with various combinations of musicians. One of these people, Kimberly, a very talented recorder player, became his wife.
Jonathan has served on the Mountain Top Board of Directors since 2009. He has also served on the Tin Mountain Board of Directors, Town of Eaton school board, Henney Scholarship Fund as a trustee, and the Town of Conway Sign Committee.
