Mr. Castillo is the founder and CEO of OGT Engineering & Construction. He started his career working in gas processing facilities, petrochemical plants and petroleum refineries for Ref-Chem while attending night school to pursue a chemistry degree. After several years of “chasing jobs” and working for other national construction companies, he decided to re-establish his roots in the Permian Basin and took a local superintendent job with Ref-Chem. Six years later, he had saved enough money to create OGT Engineering & Construction. Mr. Castillo then grew OGT Engineering & Construction from 10 employees and 2 trucks to what it is today by working side by side with many former co-workers, family, and friends. Mr. Castillo’s focus is on doing honest work with for his customer-partners while maintaining a personal relationship with his clients and reminding his team that no matter how big the company gets, they will always remain a customer-focused business.
