Strategic merger Sienna Environmental Technologies merged with Encorus Group on January 1, 2024, signaling a broader service footprint and potential cross-selling opportunities across a larger client base and expanded capabilities.

Mid-market focus With 11-50 employees and annual revenue in the 10M to 25M range, Sienna sits in a mid-market niche that frequently seeks scalable EHS programs, regulatory compliance support, and cost-effective laboratory services.

Public sector leverage Existing engagement with state agencies and educational institutions (NYS DOT, DASNY, SUNYs) indicates strong traction in government and public sector projects, where compliance, oversight, and long-term contracting are prevalent.

Full-spectrum EHS offerings Capabilities span environmental health and safety consulting, investigation, drafting, indoor air quality testing, and project monitoring, enabling cross-sell of comprehensive EHS programs, specification writing, and construction oversight.

Technology and branding A tech stack featuring web and media tools, combined with an award-winning reputation, supports marketing and client engagement efforts; potential for digital lead generation and enhanced online showcasing to attract new clients in environmental services.
