    Larry Abbott and Pete Sieker met while both were working at Pipe Organs, Inc. (an off shoot of the Alfred Kilgen firm) in Los Angeles, California in 1958. They formed the firm Abbott and Sieker in 1961, building and rebuilding mostly mechanical key action organs. In the 1960s, the firm employed about ten craftsmen, the economic slowdown of the 1970s forced the firm to build on a smaller scale. During its existence, the firm built 115 organs in Southern California. The company strove to build organs with a fine ensemble and housed in cases that were harmonious with their architectural environment.

    Staff Members who eventually started their own organbuilding businesses include Michael Bigelow, Richard Bond, Greg Harrold, and Manual Rosales.
