About the company
Vander Weele Group LLC, a woman-owned small business and self-certified small disadvantaged business based in Highland Park, Illinois, operates as a prime contractor delivering professional and administrative support services to federal agencies, with no subcontract footprint and a focus on inspector general oversight work and management consulting. The vendor holds a Subchapter S corporation structure and operates on GSA's Multiple Award Schedule, competing full-and-open without set-asides despite qualifying for small-business and women-owned designations.
Customer concentration is extreme: the Department of Homeland Security Office of the Inspector General accounts for $24.1 million of the vendor's $39.4 million combined potential value — 61% of the portfolio — from a single delivery order issued June 17, 2026, with a ceiling of $24.1 million running through December 16, 2028. This DHS OIG contract provides contractor support services in support of oversight of U.S. Immigration and Customs Enforcement detention facilities, performed in Washington, DC, on a labor-hour pricing model with no set-aside used. The next-largest customer, GSA Federal Acquisition Service, carries $9.6 million potential value, while the Department of the Interior's Bureau of Indian Affairs and Office of the Special Trustee for American Indians account for $5.3 million combined across two awards. The remaining customer base spans six agencies total, with extremely sparse activity: only eight awards appear across the source data span from 2005 to June 2026, with the vast majority clustered in early periods (2009, 2011, 2016, 2020) and a single award in 2026.
The vendor's labor portfolio on GSA's Multiple Award Schedule spans eleven categories ranging from Research Analyst 3 at $95.00 per hour (bachelor's degree, no experience required, no clearance) through CEO/Partner at $269.51 per hour (master's degree, eighteen years' experience, no clearance). No security-cleared roles are offered. Mid-spectrum capacity includes Technical Analyst 2 ($123.98/hr) and Manager ($153.05/hr), with subject-matter and technical expert roles scaling to $222.17 per hour. The portfolio's framing across administrative management consulting (four awards), educational support services (three awards), and investigation and personal background check services reflects generalist professional-services delivery rather than specialized technical capability.
Obligated dollars total $15.2 million against $39.4 million potential value (39% drawdown), suggesting the large DHS OIG contract is recently awarded and still in early execution phases. No recompete signals are visible in the sparse, episodic award pattern — the vendor operates as an occasional prime across disconnected agencies and programs rather than as a sustained prime on recurring vehicles or agency relationships. The single GSA MAS vehicle is the vendor's sole named parent vehicle, and the complete absence of subcontract work leaves no partnership signals.
