Leadership
Delta Rock & Sand is led by Jaswinder Singh, Karamjit Kaur and Vin Aggrawal — French Camp neighbors who'll know your name and your order.
Chief Executive Officer
Hands-on to the core — Jaswinder would rather be out in the yard than behind a desk. He stays close to every project, bringing years of practical know-how and the kind of relationships that get things done, so every job reflects the company’s commitment to quality, reliability, and people who actually care how it turns out.
The reason the gate opens at 7AM.
Chief Financial Officer
The steady hand behind the scenes. Karamjit keeps the finances, planning and the day-to-day paperwork running like clockwork, so the crew can focus on moving material — and you never get a surprise at the gate.
If it’s on schedule and on budget, thank Karamjit.
Chief Operating Officer
The one who makes sure your load shows up exactly when it should. Vin runs operations, scheduling and field coordination, keeping crews aligned and every project moving smoothly from the first phone call to the final drop-off.
