Charles W. Terrell, CIH, CHMM, REP

President/Technical Director

Charles started Terrell Technical Services, Incorporated, on January 16, 2003. Working from home, the initial intent, was to provide a select group of clients on-call environmental, health and safety support. Within two months, demand had increased to the point that additional employees had to be hired and a commercial office leased. The company has continued with steady growth and diversification of services.

Throughout his early career, Charles was employed by a number of environmental consulting and laboratory firms providing him with broad based experience. Charles was blessed to participate in and manage a wide range of projects, such as EPA compliance air emissions / stack testing, OSHA compliance industrial hygiene surveys, groundwater assessments, soil assessments, underground storage tank assessments, hazardous materials assessments, real estate transaction environmental site assessments and laboratory services.

Charles graduated with a Bachelor of Science degree from the University of Alabama in Huntsville with core studies in Biological Sciences, Environmental Sciences and Chemistry. While attending UAH, he met his future wife and best friend, Debra. They have two sons, Elliott and Eric, whom are completing science related degrees and are interested in carrying on the family businesses. Charles enjoys spending time with his family, fishing, hunting and improving their farms
