Masters ARS

History :

Masters ARS was acquired by the Milstead Corporation in late 2020 as part of a private sale. In existence since 2010, Masters ARS holds the valuable Southeast region TXDOT contract for environmental services along with many adjacent state, county, and municipal contracts. In late 2023 Milstead HMR was folded into Masters ARS as part of a realignment of the company to a full service, one-stop shop for transportation incident management. This newly combined organization brings the talent and experience together to offer customers a comprehensive service provider for sudden or planned events across a spectrum of needs and possibilities.
