Mr. Marty Acosta


Mr. Acosta comes to Lewis & Clark with a lifetime of experience in the machining and manufacturing field.  A career CAT man (Caterpillar Tractor Company), Mr. Acosta has worked for more than 40 years in a variety of machining and manufacturing positions.  He was in charge of the tool room machinist apprentices, electrical maintenance, and the machine repairmen.  He also worked for State Technical College training under-employed adults in St. Charles County.  

A proud native of the Windy City, Mr. Acosta is an unabashed Cubs and Blackhawks fan, although he does allow students on occasion to wear Cardinals and Blues spirit wear.  In his spare time, you can find Mr. Acosta winning bass fishing tournaments, riding his Harley, or enjoying time with his wife.

“I love to help mold someone that has little or no knowledge of machining and help them become gainfully employed in a lifelong career that will help them and their families for the rest of their lives. We are forward thinking and have the capabilities and resources to bring this to fruition. I am proud to be a member of this educational faculty.”
