John Pew


John Pew is the founder and conductor of the Timpanogos Symphony Orchestra (TSO). A fine musician in his own right, John performed the piano concertos of Grieg and Mendelssohn as a high school student and won a place in the piano studio of the famed Reid Nibley at Brigham Young University before choosing a more pragmatic path. He ultimately graduated with a degree in Mathematics and Computer Science from San Jose State University and took a job with Ariba, Inc., in Sunnyvale, California. He has kept the job in Sunnyvale, to which he telecommutes from his home here in American Fork, and he has likewise kept music, if not for his vocation, then for his avocation.

In 1998 and 2000, while living in California, John directed the orchestra and chorus for the Oakland (LDS) Temple Pageant. In 2002, he accepted the baton of the (Oakland) Temple Hill Symphony Orchestra, then a struggling organization, and built for it a vibrant reputation that attracted great soloists such as Jenny Oaks Baker. After moving to American Fork in 2005, John kept his position with Temple Hill, scheduling rehearsals to coincide with visits to the work place.

In 2007, Pew became the first and founding chair of the Arts Council’s governing board. In his three years of service he accomplished much in building the arts. In 2010, he formed the  Timpanogos Symphony Orchestra, a profound musical voice in the north county, where he continues to conduct today.
