Mabbett is successfully executing millions of dollars in Federal services through various contract vehicles including its US General Services Administration (GSA) Schedule and multi-year Indefinite Delivery/Indefinite Quantity (ID/IQ) contracts.

After nearly 27 years primarily serving the private sector, Mabbett established a Federal Services Group in 2007 due in large part to its Service-Disabled Veteran-Owned Small Business (SDVOSB) designation.
