Born and raised in the Santa Cruz mountains, Gregory has 18 years’ experience in the California landscape industry. His extensive knowledge of the construction process, passion for composition and design, and hands-on approach can be traced back to his early youth, when he developed a fascination for land development sites that surrounded his family’s home. As a child he spent every daylight hour playing outdoors in the woods, and later, surfing the waves of the Pacific Ocean.Gregory is a skillful communicator and encourages his clients to participate in the creative process. His balanced approach blends clients’ visions with their home’s architectural style and the best use of their land. He has been a resident of Santa Barbara for 10 years and lives there now with his wife and two dogs.
