TechLaw Consultants, Inc., is an employee-owned company based in Chantilly, VA, primarily doing business as TechLaw, TLI Solutions and AlterEcho—three established environmental consulting entities with decades of performance and expertise. Formerly TechLaw Holdings, Inc., TechLaw Consultants, Inc., was created in 2020 to more closely align the related operations of the three divisions under one corporate guidance structure. The company's roots trace back to 1983, when TechLaw, Inc., began operations as a government consultant to the US Environmental Protection Agency, and later other federal and state agencies. Today, TechLaw Consultants employs more than 160 people across 12 offices nationwide.

TechLaw, the name of the founding company, began operations in 1983. Since that time, TechLaw has grown into a trusted nationwide provider of technical environmental expertise in areas including remediation management and oversight, laboratory support, Potentially Responsible Party (PRP) services, risk assessment, emergency response, Environmental Site Assessments, and numerous related fields. Over the course of four decades, TechLaw has been awarded more than $1 billion in prime contracts across multiple support programs for the US Environmental Protection Agency, along with several other federal, state and local agencies and nonprofit organizations.

TLI Solutions has more than 30 years of experience providing technical environmental support in the public and private sector, working primarily in the area of hazardous waste remediation and management related to munitions and ordnance disposal.
