Project Coordinator

Cassie Westbrook and her brother Dillon represent the next generation of the family at QuarryHouse. She brings to Construction Management her expertise in professional Theatrical Stage Management and a classical art and architecture background. Her B.F.A. from Savannah College of Art and Design allows her to juxtapose a designer's artistic vision with the technical knowledge of stone masonry. Excelling in interpersonal communication and being skilled in logistics and people management make her well suited to the demands of artisan craftsmanship for high-end residential estates and public commissions.

The San Mateo native comes with an incredible background, having worked for five years in the same position at the high-end San Francisco interior design firm Kendall Wilkinson Interiors.

She also enjoys spending time with her friends, family, and two rescue cats, Elphy and Turkey.
