El Cajon Plumbing & Heating Supply Co BBB Business Review

Michael, Shelly and Loni Olsher - Family Owned and Operated since 1973!

Serving the Plumbing & Heating Supply Needs of San Diego

The Hirshman family has proudly served the plumbing and heating supply needs of San Diego County and Northern Mexico since 1973.

The history of El Cajon Plumbing and Heating Supply Co. began over 50 years ago when Mort and Naomi Hirshman (who grew up on the same street in Philadelphia!) fell in love and married.

After being honorably discharged from the U.S. Navy at the end of the Korean War, Mort and Naomi settled in New Jersey where Mort went to work for Naomi's father, Jerry Dombro, as a counterman and outside salesman at Pennsgrove Plumbing and Heating Supply.

Upon Jerry's passing in 1956, Mort and Naomi took over the family business. By 1973 the Hirshmans sold their successful plumbing supply house and moved their young family out west, where they happily adopted San Diego as their new home.

With the purchase of three acres on Magnolia Ave. and a 5000 square foot plumbing warehouse building, they proudly opened El Cajon Plumbing & Heating Co. Mort has served the El Cajon community in many ways over the years. He was a director of the El Cajon Chamber of Commerce from ’85-’88, he's a member of the local El Cajon Historical Society and a Paul Harris Fellow for Rotary International.

The Hirshmans are annual contributors to many worthy charities including Special Olympics, Make-A-Wish Foundation and the Salvation Army.

Through hard work and continued honorable service to the community, El Cajon Plumbing & Heating has become an area landmark and is an example of the truest expression of one great family’s American Dream.
