Tree Solutions

What Tree Solutions does

Tree Solutions Inc is a Seattle-headquartered consulting arborist firm founded in 1999, operating primarily in the Pacific Northwest with extension into Northern California. The firm delivers specialized tree consulting across seven service categories: health and risk assessment, advanced diagnostic testing, permits/plans/reports, treatments, GIS-based urban forestry management, construction and infrastructure tree retention, and specialty projects including expert witness testimony. Its proprietary technology mix centers on mechanical and acoustic diagnostic equipment — Resistograph micro-resistance drills, sonic tomography, Static Integrated Assessment (pull testing), increment borers, Air Spade excavation, and Arborjet's plugless trunk injection system — alongside a GIS mapping platform used for long-term urban forest inventory and management planning.

The firm serves a horizontal mix of customer segments: developers and contractors needing tree retention planning during construction, municipalities and public institutions (universities, parks, state agencies) requiring urban forestry management, residential homeowners, attorneys and insurance companies needing expert valuation and testimony, and design professionals integrating preservation into project plans. The firm maintains deliberate impartiality by not performing pruning or removal services, eliminating conflicts of interest that tree-care companies offering both consulting and physical work might carry. Long-term anchors include the University of Washington (~20 years of engagement, 8,500-tree campus inventory), Seattle Pacific University (15+ years), and High Point Housing Redevelopment (20+ years of bi-annual assessments).

The firm is privately held with no venture or growth-equity backing, no subsidiaries, and no M&A activity. Revenue derives entirely from fee-for-service professional consulting — quote-based, project-specific, and inclusive of travel time — delivered through a direct sales motion with no resellers or intermediaries. The team consists of 16 professionals including 2 principals (Sean Dugan and Holly Iosso), 5 senior arborists, 4 arborists, a CFO/HR director, a technical advisor, and a principal emeritus (founder Scott Baker, who transitioned out of day-to-day operations in April 2024). Growth is funded entirely from operations.
