Tree Works

What Tree Works does

Tree Works, Inc. is a privately held tree management and arboriculture company founded in 1978 by Michael Kraus and headquartered in Hilo, Hawaii, serving primarily the Big Island of Hawaii from offices in Hilo, Kona, and Waimea. The company delivers professional tree care services — pruning and trimming, removals, root pruning, stump grinding, brush chipping, tree diagnosis and insect/disease treatment, emergency tree care, and consulting — alongside specialized eco-friendly land clearing. It distinguishes itself technically through a fleet of three forestry mulchers (Gyro Trac GT-25XP, Gyro Trac GT13, ASV 120 FT), all fitted with Dennis Cimaf cutting heads, plus aerial trucks and cranes for canopy access, allowing it to clear thousands of acres while preserving land topography. The company employs what it describes as more ISA-certified arborists than any comparable firm in Hawaii, with founder Michael Kraus holding ISA Certified Arborist and Utility Specialist credentials.

The business operates a sales-led, quote-based model: customers reach the nearest of three local offices via dedicated phone numbers, receive free no-obligation estimates, and pay on a project basis. The customer base is hybrid and predominantly residential (homeowners needing pruning, removal, or emergency work), supplemented by agricultural operators (orchards, farms requiring selective tree removal and land clearing), government clients (e.g., Hilo Federal Building), and commercial land-development customers. Pricing is not publicly listed; project scope, equipment requirements, and site conditions determine final costs. Marketing runs through the company website, project photo/video galleries, customer testimonials, and direct phone outreach; there is no third-party distribution or platform model.

Tree Works is independent, with no institutional investors, parent company, or M&A activity disclosed. It maintains memberships in ISA, TCIA, and ASCA. Operating geographies are concentrated on Hawaii's Big Island, with intermittent project deployments documented on Mauna Kea and Oahu. The company's core economic engine is the recurring/one-time project revenue from tree services and equipment-intensive land clearing, with no recurring SaaS, subscription, or recurring-contract revenue component visible in the data.
