Over the past two decades EST has earned a reputation as a premier environmental field services company attracting a diverse client base throughout the Northeast. While we are proud of our ability to provide exceptional service to hundreds of clients annually, EST’s ability to retain these valued customers year after year is our most significant achievement as a company. In fact, almost 90% of our top 50 customers have been doing business with EST for over a decade. EST’s customer retention is made possible by a simple promise we make to all of our clients, a commitment based on three important priorities: safety, quality, and reliability.
