About UsFounded by Leonard Petersen in 1966, Petersen Precision has been manufacturing high precision metal parts for more than 50 years. After graduating from Stanford in the late 1950s, Petersen got his start in the data storage industry working for Ampex in Redwood City, California. In 1966, he set out on his own down the street from Ampex and started the metal lapping and grinding business that is Petersen Precision Engineering.
We have been operating out of our current location, coincidentally, across the street from where Ampex once operated, since 1972. By 1978, we had grown so much that a second production facility had to be built to keep up with demand for our services
By the mid-1980s, Leonard Petersen had become equal partners in Petersen Precision with his longtime friend and original investment partner Phil Olsen. A hands-on partner, Olsen was involved in the business side of our company for many years, and ran the company from the late '80s until his retirement in the '90s.
Petersen Precision Today
Today, we are still a privately-held business, co-owned by Leonard Petersen and Phil Olsen, both of whom continue to serve as active board members. Since 2016 Fred Petersen, Leonard's son, has been the General Manager of the company. Petersen Precision has expanded its capabilities considerably over the years, and we now count fineblanking, EDM and CNC machining, CNC turning, and numerous precision grinding processes among our specialties.
