“I value working in an organization with values that match my own. Social and environmental justice are strong driving forces in my life.”
David Sacamano
David Sacamano PLA, LEED AP, is our Planning and Landscape Architecture Leader and is a lifelong resident of the Pacific Northwest. He has long been drawn to the lands, waters, and weather that make the region so visually appealing and ecologically productive. In his college years, he was hooked by the landscape architecture practice because of the profession’s emphasis on open space planning, placemaking, and design of the public realm.
David is an accomplished, accredited landscape architect and urban design professional with an extensive background in master planning, site design, placemaking, and land development services. In his own words, “My favorite part of my job is working with clients and teaming with partners to solve problems and create sustainable, efficient, and attractive outdoor environments. It is both technically challenging and creatively rewarding, and allows me to blend my passions for building community and healthy natural environments.”

Mandi Roberts
Mandi is an accomplished planner and designer with over 30 years of experience. She’s worked in a wide variety of environments – across the US and abroad – at the nexus of land use, transportation, and placemaking.
She has been responsible for management, coordination, and design on a diverse mix of complex and multi-faceted projects, including research and analysis for the National Park Service, long range planning for cities and counties, as well as planning and design for transit oriented development. Those projects span multimodal transportation networks, streets and streetscapes, pedestrian and bicycle facilities, parks, plazas and other places of the public realm.
Known as a national expert in multimodal transportation, Mandi has been an invited speaker at many national, state, and regional conferences. She is an excellent communicator and facilitator, and her strong expertise coordinating with multiple government agencies, technical experts, tribal nations, regulatory decision makers, and other diverse interests has led to many successful projects. She enjoys working closely with communities, special interest groups, neighborhoods, and the public in bringing their visions to reality.
Chad Weiser
Growing up the son of a soil scientist, Chad developed a love of plants and the environment from an early age. This passion led him to become a Landscape Architect and the Principal Landscape Architect and Federal Practice Area Leader for Otak’s Redmond, Washington office. Since joining the company in 1999, Chad has greatly appreciated the numerous opportunities to work on a wide variety of different projects and practice groups, all which have strengthened his design and leadership skills. He is continually inspired by the new ideas his colleagues bring to the table and thrives when he is working on a challenging project.
Outside of work, Chad has been an active volunteer and board member on multiple organizations in his local community that support youth sports including the Thunderboard Little League, Somerset Swim Team, and the Newport Booster Club. His volunteerism has allowed him to support the growth of children, but has also allowed him to be more engaged with his own children’s activities. In addition, his love for the outdoors has led him to support conservancy organizations such as Yellowstone Forever and Yosemite Conservancy, both of which serve to protect the delicate ecosystems of these two iconic national parks.
