Hull & Associates

What Hull & Associates does

Hull & Associates is a private environmental science and engineering consultancy founded in 1980 and headquartered in Columbus, Ohio. The firm delivers integrated environmental and engineering services — including CERCLA/RCRA remediation, environmental assessment, environmental health and safety, natural resources planning, sustainability advisory, and a full suite of engineering disciplines (architecture, automation, electrical, geotechnical, hydrology, mechanical, site/civil, structural, surveying, water/wastewater) — to clients across power delivery, water, government, industrial, renewable energy, transportation, power generation, technology, real estate, and oil & gas markets. The company distinguishes itself from traditional siloed E&E firms by combining environmental science and engineering under a single platform and has productized specialized offerings in Superfund liability management, river/flow-related solutions, hydropower, and digital technologies. Following a 2020 investment from RTC Partners, the firm has pursued an aggressive roll-up strategy, completing multiple acquisitions (HSW Engineering and Duffield Associates in January 2021; Yu & Associates in June 2026) and repositioning its market identity under the Verdantas brand with a US-and-India delivery footprint. Revenue mechanics are project-based, bid-driven B2B professional services delivered to enterprise and government clients through a direct sales model and online plan room, with no public pricing disclosure.
