About C.j. Seto Support Services, LLC
C.j. Seto Support Services, LLC is a veteran-owned, minority-owned small business registered in SAM.gov since 2001 and headquartered in Ventura, California. The company is a professional services provider specializing in environmental management, industrial hygiene, technical support, and professional consulting services across various federal agencies. As a diverse small business, C.j. Seto holds multiple certifications including Service-Disabled Veteran-Owned Business, Asian-Pacific American Owned, and DOT Certified Disadvantaged Business Enterprise, which enables the company to compete for a wide range of federal contract opportunities.
The company has provided extensive environmental sampling, hazardous materials management, and technical support services primarily to defense agencies, including the Department of the Navy, Department of the Army, and Department of Veterans Affairs. Most of its contract awards involve environmental services such as asbestos and lead paint sampling, building demolition sampling, industrial hygienist services, water sampling, and environmental survey work. These contracts are predominantly delivered through task orders at facilities like Naval Support Activity Crane in Indiana, with contract values ranging from a few thousand to over $200,000. While many contracts have no specific set-aside designation, C.j. Seto has successfully secured some small business and service-disabled veteran-owned small business set-aside contracts, demonstrating its versatility in meeting federal agency requirements.
C.j. Seto Support Services holds three significant federal contract IDVs: a $300 million single-award Indefinite Delivery Contract with the VA Office of Construction and Facilities Management focused on environmental consulting and sustainability services, another $300 million single-award IDC also with the VA, and a $300,000 Blanket Purchase Agreement with the Chemical Safety and Hazard Investigation Board for industrial hygienist services under the GSA Multiple Award Schedule. These IDVs provide the company with substantial opportunities to deliver professional services across multiple agencies, with contract periods extending through 2029-2031. The IDVs cover a broad range of services including environmental contamination analysis, historic preservation consulting, sustainability assessments, and industrial hygiene support, requiring multidisciplinary expertise in scientific, engineering, and technical domains.
