Two Landscape Architecture Firms Merge

studioINSITE developed the Denver Justice Center.

Denver landscape architecture, planning and urban design firm studioINSITE has joined forces with Midwest-based landscape architecture firm, Confluence. With eight additional locations outside of Denver, Confluence has emerged as one of the most comprehensive, growth-oriented landscape architecture, planning and urban design firms serving clients throughout the Midwest and Western U.S.

“This new chapter allows us to provide immense value to our clients as we combine studioINSITE’s creativity and deep market knowledge with Confluence’s vast reach, resources and design leadership,” said Dennis Rubba, FASLA and founding partner at studioINSITE. “Beyond our service alignment, we are integrating two teams with shared values and well-aligned processes. We look forward to working together to continue delivering elevated solutions for our clients while improving the quality of life in communities across the West and Midwest.”

Under the new combined structure, studioINSITE founding partner Dennis Rubba, FASLA, will assume a senior principal role and continue to lead the Denver office in collaboration with Chris Sutterfield, PLA, ASLA and Gary Worthley, PLA, ASLA, who will assume the role of managing principal of the office. All nine studioINSITE team members will be integrated into the Confluence team of over 60 designers, planners, creators and facilitators nationwide. Confluence plans to further grow the Denver office in line with project and client demand.

Founded in 2001, studioINSITE is nationally recognized for the design and implementation of high-profile projects throughout the country. Notable work includes the redevelopment of 14th ‘Ambassador’ Street in downtown Denver, the revitalization of Old Town Square in Fort Collins, and a 3,700-acre master plan for Staunton State Park, Colorado’s newest state park. The firm is also known for its resort work in mountain communities, including Snowmass Village in Snowmass, Colorado, as well as national work on projects such as Semper Fidelis Memorial Park overlooking the National Museum of the Marine Corps, Quantico, Virginia.

Like studioINSITE, Confluence specializes in landscape architecture, planning and urban design and has completed hundreds of projects over the last two decades. Originating in the Midwest, Confluence’s work now spans a variety of geographies and project types – from integrated mixed-use developments, urban districts and campus planning to parks and open space, and hospitality and resort destination work. Over the last two decades, Confluence has completed hundreds of projects including the Minnesota Vikings practice facility and Viking Lake Developments, Krause Gateway (in collaboration with Renzo Piano Workshop) in Downtown Des Moines, the redevelopment of historic Seaton Hall/Regnier Hall at Kansas State University,  the Iowa State Capital West Terrace, the Downtown River Greenway in Sioux Falls, South Dakota, and the Streetcar Starter Line in Downtown Kansas City, Missouri.

“We see Denver as a vital hub for Confluence’s work across the Rocky Mountain Region, Western markets and beyond,” said Wm. Christopher Cline, PLA, ASLA, APA, senior principal and senior vice president at Confluence. “The acquisition of studioINSITE puts our combined team in a position to better serve our clients wherever their project opportunities arise with greater capacity, and more robust on-the-ground resources and in-market insights.”
