Family-Owned. Three Generations Strong.
Cal South Premier has been building San Diego County's outdoor spaces for 39 years — the same family, the same standards, one generation to the next.
Jerry Castellanos Built This on Hard Work
In 1987, Jerry Castellanos started what would become Cal South Premier Landscape & Hardscapes — one job, one handshake at a time. Jerry believed in doing the work right, showing up when he said he would, and treating every yard like it was his own.
Over the decades, Jerry passed that knowledge down to his kids and grandkids, teaching them the trade from the ground up: how to set a form, grade a yard, and build a wall that will still be standing in fifty years. Jerry is no longer with us, but his standards are non-negotiable — every project the family builds today carries his name and his reputation.
Today the next generations — led by Mike and foreman Ruben — carry the business forward, backed by a crew that's earned a perfect 5.0 rating across 20 Google reviews.
