About ACE

Our History

Ace was formed by Randi Barra and Rick Rasmussen in 2005. There were no other employees at that time – the owners handled anything and everything. After several months of a lot of work, little sleep and no paycheck, they hired the first employee and the company began to grow slowly. Over the years, the company purchased equipment and hired qualified employees. All profit that was realized was invested back into the company. The company philosophy of controlled growth allowed Ace to keep debt low and the company strong. Today, Ace has the best employees in the industry and a growing fleet.

Ace has serviced the Baltimore-Washington Metro area since 2005. At Ace, we combine the resources of our technical experience and our skilled workmanship, which results in a complete work implementation, centralized management, and single-point of contact for communication. We have developed our company to provide highly efficient, cost-effective and professional services. Ace is your trustworthy partner when it comes to various environmental services. Ace is a full-service environmental contractor specializing in 24-hour emergency spill response, tank management, industrial cleaning, hazardous waste and non-hazardous waste disposal and site assessment/remediation projects.

In October 2018, Ace Environmental Services, LLC became Ace Environmental Holdings, LLC.
