Mark Middleton started GLY-TECH SERVICES, INC. in 1987, with only four employees. GLY-TECH slowly began its growth and success journey, becoming a company providing expert value-added services to our customers now for over 34 years. He always said, “Without our dedicated and loyal employees, GLY-TECH would not have achieved our customers’ respect as a value-added service company.” Today, GLY-TECH employees are recognized as very safe, high quality, and professional experts in the oil and gas industry.
