Residential Landscape Designer
Growing up in the industry, landscape design and construction have always been a passion. After earning my horticulture degree with a landscape design focus from Cal Poly, I’ve loved transforming outdoor spaces into living sanctuaries. Working closely with clients, I create unique landscapes that reflect their personality and invite them to find peace and enjoy their home in new ways. Whether it’s a few plants or a full property remodel, let’s build something extraordinary!

Residential Landscape Designer
My design philosophy centers on my clients’ needs and desires—rather than focusing on my own creation, I use my expertise to find what best matches their goals. Open conversation is key—I listen closely, share suggestions, and collaborate to bring their vision to life, offering creative ideas they may not have considered to make each landscape both functional and beautiful. I take joy in exploring a wide range of design styles, from ultra-modern to traditional Japanese.

This hands-on background gives me a unique perspective as a landscape designer. While my expertise is in hardscaping, I envision each project as a balance of function and aesthetics, guided by the client’s needs and budget. I believe every outdoor space should reflect its owner, combining form, purpose, and style.
