GCS Glass and Mirror Long Island, initially known as Sea Glass Interiors, is a testament to the determination and spirit of its founder, Derek. Our story began in 2021 but Derek's journey in the glass industry started even earlier, back in 2012 in Boston where he began installing showers.

Derek's passion for the glass industry wasn't just a 9-5 commitment. Even while working offshore on commercial vessels as a merchant mariner, he continued to cultivate his glass business on Long Island, demonstrating his unwavering dedication and resilience.

The partnership with GCS Glass was a natural evolution of Sea Glass Interiors. Derek was drawn to GCS Glass because its vision and brand identity resonated with what he had built at Sea Glass Interiors. The alignment in ethos and values made the decision to join forces with Brandon and Chance an easy one. He saw the potential in proudly representing and building GCS Glass and Mirror alongside them.

Today, Derek continues to bring his expertise and passion to GCS Glass and Mirror Long Island, fostering an environment of quality, customer satisfaction, and innovation. His journey from Boston to Long Island and from Sea Glass Interiors to GCS Glass is a testament to his commitment to delivering the best in the glass industry.
