The story
The company's founder, Charles George Hendrickson, was born on 10 June 1935 in Willmar, Minnesota. He studied physics, which he then taught at various US colleges. He started working part-time on pipe organs as a graduate student, and began the company in December 1964 while teaching at Minnesota State University.
Since then, over 100 pipe organ projects have been completed. Along with new pipe organs, the firm has restored old instruments, relocated instruments, and rebuilt and enlarged existing pipe organs. The firm also provides service work and tuning for approximately fifty organs.
In 1999, the company had 7 employees and earned "mid-$300K" in sales.
Charles Hendrickson died on 17 December 2020 and was succeeded by his son Andreas Hendrickson as president.
