Lesbia Martinez recently acquired sole ownership of TES in March 2021. Lesbia has worked with Gary Lang (former co-owner) since 1993. She has helped the company grow through relationships built with accredited individuals and contractors in the industry. Her experience in the industry started with understanding the guidelines set out by the EPA and OSHA for training asbestos certified individuals. She has become a subject-matter expert on regulations, training, certification, and specialty contracting, specifically in environmental remediation.
