documenting an awesome workshop led by Brenna Hansen and hosted by the East Bay Photo Collective at the community darkroom in Oakland. it was so fun to learn how to develop cyanotypes using our own photo negatives, tone them, and try out the process on my own. thank you Brenna for sharing your knowledge and teaching us this craft.

a quick photogram from some neighborhood plants at the end of the day for fun.

I am a landscape designer and engineer-in training currently practicing in the San Francisco Bay Area. I grew up in Arizona, where I developed a deep appreciation for water and resilient desert landscapes. I obtained my Bachelors degree in Civil Engineering from Arizona State University before achieving my Masters degree in Landscape Architecture and Environmental Planning from UC Berkeley in 2023. I currently practice at Restoration Design Group in West Berkeley, where my work integrates ecological restoration and watershed principles with grading, infrastructure design, and thoughtful site planning. I'm currently pursuing licensure as a professional landscape architect in California and am interested in expanding my work further into the American Southwest.
Along with my design practice, I enjoy practicing alternative photography to creatively explore landscape, texture, and light. Photography has challenged me to deepen the way I observe and understand environments and the relationship between people, water, and place.
This online portfolio is intended to share my work and to express creativity, curiosity, and appreciation for the environment. I'm always interested in collaborating, whether it be related to landscape and drainage design or a photography project.
