Washington OMWBE-certified Women's Business Enterprise (WBE) for corporate diversity-spend programs, public-sector RFPs, and institutional ESG reporting. 100% woman-owned. 20+ years operating Seattle.
Emerald Cleaning LLC (DBA Emerald City Cleaning) was founded in 2013 (Guacolda has cleaned Seattle since 2003). Guacolda Zinsmeyer is the 100% sole member-owner — the operating agreement, the bank signatory cards, the OMWBE certification, and the strategic direction of the company all point to the same person.
Your procurement-compliance team can verify everything: WA OMWBE certificate M5F0024884 is searchable at omwbe.wa.gov. City of Seattle and City of Bellevue business licenses on file. Insurance on file. References on file with permission.
If your diversity-spend program requires Tier-1 reporting, our state OMWBE typically counts directly. If it requires federal SBA WOSB or NMSDC certification, our OMWBE supports Tier-2 reporting and we can submit any additional documentation your procurement team needs.
If you're under a diversity-spend mandate, an ESG reporting requirement, or a public-sector procurement rule, our OMWBE certification gives your team a verified diverse vendor in commercial cleaning.
Tier-1 supplier diversity teams at Seattle-area corporates (tech, healthcare, banking, retail) with annual diverse-spend targets and reporting obligations.
If your primes report Tier-2 diverse spend back to their customers, we are a documented WBE second-tier subcontract option.
State, county, and city procurement with diversity-aware scoring. Registered in WEBS. OMWBE-preferenced on solicitations that include diversity criteria.
Port-controlled facilities, transit, public-authority buildings with explicit diverse-spend goals and preference scoring.
REITs and institutional asset managers with ESG reporting obligations — diverse-vendor selection is a documented S-factor in ESG.
If you're bidding public construction with diverse-subcontractor utilization goals, we are an eligible OMWBE final-clean subcontractor.
