Our Story

Our History 

JSC Agricultural Supply was founded as Jim’s Supply Co., Inc. in 1959 by Jim and Doreen Boylan. The company started as a structural steel and pipe supplier and in the 80s, expanded to include full on site production of metal trellising materials. Around this same time, JSC also became a distributor of agricultural and fencing supplies to complement their trellising solutions.

2017 brought exciting growth for JSC. An expansion into the retail market brought forth an online store. A new retail location in 2018 in Delano, CA  soon followed. The growth allowed for JSC to expand their product line even further as they began distributing everyday farming and field supplies, including personal protective equipment, harvest, pruning, safety/PPE, sanitation, and misc. contractor supplies.
