Mark Larosee

Mark Larosee serves as a key procurement lead at U.S. Coast Guard Base Seattle (70Z033), responsible for managing facility and infrastructure support contracts critical to operational readiness. His role centers on acquiring specialized services that maintain the integrity of maritime infrastructure, including building systems, environmental compliance measures, and utility maintenance. He oversees the full lifecycle of acquisitions—from requirements definition to contract award and administration—ensuring alignment with federal procurement regulations and the Coast Guard’s mission to sustain resilient coastal operations. His portfolio is narrowly focused on hazardous waste management and site remediation services, reflecting the base’s priority on environmental stewardship and regulatory compliance. Larosee maintains consistent working relationships with a core group of contractors including VCloud Gov Inc., Astrallic Inc., M.B.A. ADHC LLC, Victory Contracting LLC, and John’s Waterproofing Co., all of whom deliver specialized environmental and facility maintenance services. These partnerships are characterized by repeat engagements and deep technical alignment with the base’s infrastructure needs, indicating a preference for vendors with proven expertise in hazardous waste handling, containment systems, and industrial site remediation. His contracting approach emphasizes reliability, regulatory adherence, and performance-based outcomes over competitive bidding alone. Larosee’s procurement activity shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a mission-driven focus on technical capability and compliance over socioeconomic preferences, prioritizing vendor expertise in hazardous waste management above demographic certifications. While small business participation is not formally encouraged through set-asides, his contracting patterns remain transparent and compliant with FAR guidelines. His primary procurement focus is exclusively on NAICS 562112 (Hazardous Waste Collection), underscoring deep technical expertise in environmental remediation, chemical containment, and regulated waste disposal. He procures services related to hazardous material handling, spill response, decontamination, and compliance reporting—ensuring Coast Guard facilities meet EPA and USCG environmental standards. His domain expertise lies in the intersection of federal environmental regulation and infrastructure sustainment.
