In addition to teaching, Ms. O’Hara practices landscape architecture and historic landscape restoration.  She is a principal of m + o landscape architecture which concentrates on contemporary design in sustainable and green infrastructure solutions.  This practice also includes the specialty niche of consulting on the restoration and preservation of historic landscapes by writing National Register Nominations and Cultural Landscape Reports, as well as restoration and rehabilitation plans for such projects as Rancho Los Alamitos (Long Beach, CA), Mountain View Cemetery (Piedmont, CA), Malaga Cove Garden (Palos Verdes Estates, CA), Righetti House (San Luis Obispo), and Hollywood Bungalow Courtyards (North Hollywood, CA).   Ms. O’Hara is on the board of the California Garden and Landscape History and is a trustee for the National Association of Olmsted Parks.   She views history and contemporary design as companion ideas where history provides the framework for understanding the direction of the field of landscape architecture.

Janet Enright

JE Landscape Design

Janet Enright, Principal and founder of Janet Enright & Associates, has been designing landscapes since 1985.   She provides landscape design and consultation services across the San Francisco Bay Area, using principles and practices that promote sustainable gardens that thrive in our Mediterranean climate.

Along the way, she’s studied with John Brookes at La Napoule Foundation in France, at UC Berkeley Extension Landscape Architecture Program, at Foothill Community College Environmental Horticulture and Design Program … and generally enjoys messing around in dirt.  Her diverse work experience includes driving a lift truck at her Dad’s lumber yard in high school, owning a floral design business, being an educator, and teaching at Santa Clara University.

Landscape design became Janet’s primary focus in 2005.  In her prior career in education, she was a School Principal at Juvenile Hall – not exactly what most people would consider likely experience for a landscape designer.  Think again – they both require the ability to see the larger picture and make sense of it, to understand the needs of the client and offer solutions they can embrace, and to have a well-grounded working knowledge of how to get them where they need and want to be – whether it’s in school (and out of jail) or in their garden.

Growing up, she was privileged to spend time on her family’s property adjacent to Big Basin Park – a wondrous education in the wild.  Throw in years of honing an artistic aesthetic through sculpture, painting and collage, and it all coalesces.

Janet is a Bay Friendly Qualified Landscape Professional, and 2011 Past President of the Association of Professional Landscape Designers, California Chapter.

Daniel Mount

Daniel Mount hails from a long line of wandering gardeners, nurserymen and farmers.  He received his first shovel for his second birthday and began his gardening career in the sand box later that afternoon. Spending most of his youthful summers in a vegetable patch, on a farm, in parks, or in the woods, the curiosity of a scientist and the soul of a poet were awakened in him. Daniel went on to study fine arts and botany at the University of Wisconsin-Milwaukee, from which he received a BS in Botany.

Drawn to the legendary gardening climate of the Pacific Northwest, Daniel moved to Seattle, Washington in 1988. Since that time he has created, maintained and consulted on gardens primarily in the Puget Sound Basin. The skills he acquired working in the passionate gardening environment of  Pacific Northwest have opened many doors. Daniel was invited to Cologne, Germany, where he worked on urban rooftop and courtyard gardens as well as rural estates. He was next called to Orto dei Semplici Elbano on the Island of Elba, Italy where he collected and designed with the unique flora of this island.  He maintains an ancillary connection to this garden to this day. Closer to home he has consulted on projects and designed gardens in and around Durham, North Carolina; Milwaukee, Wisconsin and Phoenix, Arizona.

Daniel has settled on a small farm nestled in a 150-acre bird sanctuary, which he shares with his partner, innumerable slugs and a bear, in the Snoqualmie River Valley east of Seattle. He enjoys growing organic vegetables and fruits, raising ducks and experimenting with flood tolerant plants. He creates gardens and also teaches and writes about plants and gardening.
