Prior to joining Mark Tessier Landscape Architecture, Inc., Jessica developed her sense of regional appropriateness and sense of place during architecture and planning work in New Orleans, Portland and Los Angeles as well as landscape design work in France.

Jessica’s interest in how a community interacts with its surrounding landscape has led her to participate in artist Fritz Haeg’s “Wildflowering L.A” – a project which brings a wild and beautiful seasonal native landscape to open plots and culminating in an exhibition and tour.

Lucie Siggins

Lucie was immersed in nature and influenced by the outdoors throughout her childhood as a California native. This connection to the landscape would eventually lead her on a circular path away from and back to California.

Before joining the team at Mark Tessier Landscape Architecture, Inc., Lucie honed her refined, minimalist design sensibility through her degree in Studio Art from Loyola Marymount and her work in architecture and interior design in San Francisco and New York. Being inspired by the potential to enhance the quality one’s life through design as well as understanding the profound impact nature had on her own aesthetic, Lucie returned to school to earn a Master Degree in Landscape Architecture from the University of Georgia. She eventually returned to Southern California to combine her love of California’s diverse landscape and her desire to bring people closer to the earth with her passion for design.

Lucie is interested in creating environments that focus on both aesthetics and experience simultaneously, reducing elements to their essentiality to create a heightened, but quiet awareness of nature. Ultimately, she believes that a person’s connection to the landscape can both calm and contribute to a happier, healthier life.
