It has been a great experience for Erie High School and myself in dealing with S.J. Smith and Mike Gay. Mike's knowledge and dedication to his trade is a valued asset to S.J. Smith and has benefited myself and Erie School District immensely. Tod McCullough, Industrial Technology Instructor, Erie High School, Erie, Illinois
