Lukas Coker, Senior Landscape Designer
Lukas has worked on a range of project types including high-end residential, streetscapes, mixed use commercial, and ski resorts. He has worked as a designer on projects throughout the Denver metro area, multiple US states and Asia.
Lukas grew up in northern New Mexico, spending the first ten years of his life living in Bandelier National Monument where his father was a Park Ranger. This instilled a love and respect for nature and has greatly influenced his design thinking. Lukas focuses on integrating climate appropriate plantings and local materials when possible to create drought tolerant sustainable landscapes that highlight native flora and provide an enjoyable experience for its users.
On the weekends you can find Lukas up hiking or camping in the mountains, gardening at home, volunteering at the Denver Botanic Gardens or enjoying a beer at one of his favorite Denver breweries.
