What Environmental Service Partners does

Environmental Service Partners, operating as ESP Facility Services, Inc., is a privately held commercial janitorial and facility services company founded in 2010 by Mike Greenberg and headquartered in Hayward, California. The company delivers janitorial, comprehensive facility management, and specialty cleaning services across nine verticals — including commercial office, hospitality, healthcare, life sciences, sports and entertainment, industrial and manufacturing, multi-family residential, public sector, and retail — primarily serving Northern California (Bay Area and Sacramento). ESP reports cleaning approximately 25 million square feet of space (including 5 million square feet of hotel space nightly and operations such as Levi's Stadium) and supports more than 350 clients with roughly 800 associates, posting a stated 98% annual customer retention rate and an 8-year average employee tenure.

The company's service offering is anchored by an exclusive, EPA-registered, EcoLogo-certified biological cleaning product called BioClean 2X, which the company positions as up to 90% more effective than traditional chemical cleaners. Around this, ESP has built a proprietary technology layer — the ESP Performance Engine (BI platform), ESP 25/8 Connect (cloud-based service platform), 3PI Metrics and Reporting, the ESPU Training learning management system, and the ESP Account Manager dashboard — used internally for performance tracking, training, and client reporting. The BioClean 2X product is also sold through HD Supply Solutions distribution.

Revenue is generated primarily through managed-services and professional-services contracts: custom, quote-based, multi-year enterprise agreements with facility size and scope as the basis for pricing, complemented by product sales of BioClean 2X. Go-to-market is sales-led and enterprise field-sales driven, with dedicated account and regional account managers, phone-based inbound (800-313-4077), and a website quote-request channel. ESP emphasizes long-term, scalable partnerships with named anchor clients including Hyatt, Hilton, CBRE, Colliers International, Newmark, Accenture, Healthcare Realty, ArsenalBio, Woodmont, Windsor, Bozzuto, Behring Co, and Levi's Stadium. The company is founder-owned with no disclosed external or private equity investment.
