A Texas nonprofit that recently hired a Biden transition official got a contract worth as much as $530 million to help manage the influx of migrant children at the southern border, Axios has learned.Why it matters: The contract is by far the largest ever awarded to Family Endeavors. It’s potentially worth more than 12 times the group’s most recently reported annual budget — a sign of the demand the new work will place on its operations.Get market news worthy of your time with Axios Markets.

Between the lines: Family Endeavors won the contract just months after it hired Andrew Lorenzen-Strait as its senior director for migrant services and federal affairs.Lorenzen-Strait, a former official at U.S. Immigration and Customs Enforcement, previously advised the Biden-Harris transition team on Department of Homeland Security policy and staffing matters.He also ran a consulting firm advising companies on federal procurement practices, according to his LinkedIn page, with specific expertise on agencies that include the Administration for Children and Families — the division of the Department of Health and Human Services tasked with detaining and processing child migrants.The Washington Examiner first reported on Lorenzen-Strait’s role at Family Endeavors, in the context of an $87 million DHS contract awarded to the group last month.ACF officials did not respond to a request for comment from Axios. Family Endeavors said its contracting work on the border is “a continuation of services we have delivered to the migrant population since 2012.”What’s new: ACF contracted Family Endeavors last month to provide “emergency intake” and “wrap-around care” services at a temporary facility in Pecos, Texas.According to federal procurement records, ACF has disbursed $255 million to the nonprofit under the new contract, which has a maximum potential value of $530 million.Family Endeavors’ most recent publicly available annual tax filing, covering calendar year 2018, showed its annual budget for the year was just $43 million.Before last month, it had never received a prime contract award from HHS, though, according to a source familiar with Family Endeavors’ operations, it did provide staffing services at migrant intake shelters run by another HHS vendor, BCFS, in 2012, 2014, 2016 and 2019.The big picture: Other large ACF contracts went to for-profit firms with more experience working on such large-scale operations.The agency awarded more than $320 million to Rapid Deployment, a company whose CEO has been nicknamed the “master of disaster” for the extensive relief work his firm has done. It’s also received nine-figure Pentagon contracts for work on military base camps.The only ACF contract larger than Family Endeavors’ was a $719 million award to Deployed Resources last month, of which about $273 million has been obligated. That company also does extensive work for DHS and the Defense Department.Like this article? Get more from Axios and subscribe to Axios Markets for free.
