What STIMSON does
STIMSON is a privately held landscape architecture firm founded in 1992 by Stephen Stimson, FASLA, and headquartered in Princeton, Massachusetts with a second studio in Cambridge, Massachusetts. The firm provides professional landscape architecture and design services — including master planning, planting design, and construction administration — across three primary service categories: Parks + Museum (public spaces, memorials, cultural landscapes), Academic (campus planning), and Garden (residential estates and private gardens). STIMSON is vertically organized around Higher Education (Harvard, MIT, Williams, Northeastern, Boston College, Brown, Bowdoin), Municipal Governments (City of San Antonio for Phil Hardberger Park; Forest Park in St. Louis for Government Hill), Cultural Institutions (Cleveland Museum of Art Fine Arts Garden; Dr. Seuss National Memorial), and High-Net-Worth Private Residential clients.
The firm operates as a principal-driven B2B professional services practice using a project-based fee model with no publicly disclosed pricing; client acquisition runs through direct engagement, RFPs, design competitions, and referrals from architecture partners. STIMSON collaborates strategically with marquee firms including Olson Kundig Architects, Cambridge Seven Associates, ARUP, Rialto Studio, SOM, HOK, and Piet Oudolf. A distinctive operational asset is Charbrook Farm, the Stimson family's historic 1743 Princeton dairy farm, which functions as both a working nursery supplying project plant material and an R&D platform for native plant propagation and ecological design. The firm is licensed in 15 U.S. states and has active commissions in Canada.
STIMSON's revenue mechanics are tied to large-scale, multi-phase institutional and municipal projects (e.g., the 311-acre Phil Hardberger Park including its landmark land bridge, the 1,371-acre Forest Park Government Hill area, the 40-acre Cleveland Museum of Art Fine Arts Garden rehabilitation), with revenue recognition aligned to design and construction administration milestones. The firm holds 11-50 employees and is led by Stephen Stimson (Founder/Principal), Glen Valentine (Principal, FASLA), Joe Wahler (Principal, ASLA), and Edward Marshall (Principal Emeritus, FASLA). STIMSON was named the 2021 ASLA Landscape Architecture Firm of the Year and won four ASLA awards plus multiple SCUP and BSLA honors in 2025-2026.
