Our Purpose

Our Journey Begins: Crafting Quality Concrete

In the early 1990s, Mesrop stepped into Southern California’s construction industry, dedicating himself to installing natural stone and precast concrete products. His unwavering commitment and fine craftsmanship earned him pride and success among his clients.
As time passed, Mesrop expanded his horizons. He ventured into manufacturing architectural precast concrete, gracing some of Los Angeles’ most exquisite estates. In the early 2000s, his son joined the family business, aiming to conquer commercial projects.
Today, Mesrop’s son, JB, with over 25 years of concrete mix chemistry expertise, oversees the day-to-day operations at Trrimstone Products LLC. Our focus is Delivering top-notch precast concrete pool coping stones and other products to swimming pool builders, homeowners, and designers.
