At ETI School of Skilled Trades, the teachers make the difference.

Christopher McKee

A 4 year veteran of the United States Marine Corp, Infantry Lance Corporal Christopher McKee has been working in the HVAC/R field for the past 18 years.

Christopher encourages his students to stay motivated and to set goals for themselves. He agrees with Vince Lombardi in saying; “The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack of will.”

Jerry Ray

He emphasizes to his students, just as Bill Parsons did to his players, “You are what your record says you are”.
