Gretchen Whittier, Associate Partner, Landscape Architect, ASLA
With a childhood filled with days of eating tomatoes and strawberries straight out of her mom’s organic garden, and assisting her father build brick fireplaces, becoming a landscape architect may have been inevitable for Gretchen.
A designer with Arterra since 2005, she believes in working with the natural landscape to create dynamic spaces that are comfortable and whimsical. Her design and environmental aesthetic extends to her home and garden, which is an eclectic blend of mid-century modern, found objects and re-fabricated furniture and materials.
Gretchen graduated from Phillips Academy Andover, then received a B.A. from University of Vermont, followed by a Certificate in Landscape Architecture. Outside of the office, Gretchen can often be found rummaging through salvage yards for the next great inspiration, planning elaborate birthday parties for friends, snowboarding or socializing kittens for the animal rescue group she volunteers for and is a board member of.

Elizabeth Melara, Landscape Architect
Elizabeth graduated from California Polytechnic State University, San Luis Obispo in 2009 with a bachelor’s degree in Landscape Architecture and a minor in Sustainable Environments. The highlight of her education was spending a year in Florence Italy, studying Architecture. She became inspired by the rich Italian landscape, ranging from its subtle undulating hills to its striking red-roof cities.
Elizabeth has always been interested in the blend between nature and built form.
With an understanding of the greater need for protecting and conserving the earth’s delicate resources, she hopes to become LEED certified in the near future. She also wants to return to school to get her masters in urban design.
In the meantime, she enjoys living in the dynamic city of San Francisco and spends her free time painting, reading and testing out new recipes, which she tests on her brave friends.
Alyssa Erickson, Design Apprentice
Alyssa was born and raised in Santa Barbara, California.There she enjoyed the landscape by hiking in the mountains smelling the sage, and surfing in the ocean, tasting the salty sea. She loves her native land, but craved the city life which brought her to San Francisco to study industrial design. She then designed products for the home, and also performed space planning for systems furniture.
She changed career paths because she wanted to make more of a positive impact on the earth, and landscape design became the natural choice. She was one of the first 3 to graduate from Merritt Collegeʼs newly developed associate of arts degree in landscape architecture, and graduated with the highest honors. One of Alyssaʼs favorite things about landscape is to design with plants that have strong architectural form that serve a purpose in the landscape.
Alyssa likes to spend her free time cooking with friends, practicing Iyengar yoga, dreaming of sailing in the ocean, and building her vinyl collection of classic rock, jazz and 80ʼs pop music.
Dani Winston, Design Apprentice
Dani Winston became a design apprentice at Arterra after completing the Master of Landscape Architecture program at UC Berkeley.
Dani studied art and design, with a focus on commercial photography, at Cal Poly San Luis Obispo. He then worked as a commercial photographer for many years before discovering landscape architecture. While scouting locations in Manhattan, he came across a derelict, elevated rail running over the streets and through buildings. A friend told him that people wanted to turn it into a park. This inspiring idea stuck with Dani and he couldn’t wait to start working on his own projects.
When not at work Dani can be found in his garden growing a vast array of fruit and vegetables, barreling down winding dirt trails on his mountain bike accompanied by his faithful dog, camping and traveling the world.
