ASHLEY GRECH
From an early age, Ashley had an undeniable passion for design. Whether rearranging her bedroom furniture or customizing her wardrobe, she instinctively understood the power of aesthetics and spatial harmony. Her father’s fascination with home plans, new developments, and model homes became a weekend ritual they shared—fueling her curiosity and shaping her eye for architecture and interiors.
In high school, a drafting class solidified her path, leading her to earn a BA in Art with an emphasis on Interior Design from CSU Chico in 2008. Ashley’s natural talent and relentless drive set her apart, and she quickly built a career in the corporate design world, refining her expertise in high-end interiors.
Growing up in a family of entrepreneurs, she witnessed firsthand the resilience and dedication it takes to build something extraordinary. Inspired by that spirit, she founded Thirteen Oak, an architectural and interior design firm rooted in Northern California. Today, Ashley and her team craft bespoke, timeless interiors that seamlessly blend beauty, functionality, and a deep understanding of their clients’ lifestyles.
With an unwavering commitment to excellence, Ashley continues to shape refined, sophisticated spaces that feel both luxurious and deeply personal—transforming houses into extraordinary homes.
