Our team of instructors bring many years of industry experience, extensive knowledge from the trade and diversity into the classroom with their varied backgrounds. They’re committed to teaching and helping students learn all facets of machining, from math, blueprint reading, shop theory, to cutting and creating actual parts from metal blocks. The practical hands-on experience is designed to progress and challenge the student throughout their program. We train to build leaders, to keep manufacturing strong and provide the industry with skilled and proficient machinists.

Team of Instructors

    Kurt Preisendanz

    Director of Training

    Kurt started as a general machinist in 1974. His apprenticeship started in his father’s machine shop in Pasadena, California. In his 4 years of apprenticeship, Kurt was involved with machining and processing for the aerospace industry. For the next  5 years (1978-1983), Kurt worked in various job shops as a general machinist in the San Fernando and Santa Clarita Valley’s where his duties include conventional machining, CNC machining and programming, fixture design and building, and troubleshooting. From 1983-1990, Kurt became a contract machinist for a company directly involved with Space Shuttle Main Engines (Rockwell International, Rocketdyne). This contract position eventually led to the start of Kurt’s own Machining and Design Company called Kersey Manufacturing. After 4 years, Kurt was asked to become a General Manager for a major aerospace and defense contractor, which he accepted. From that point on, Kurt has been involved as a Senior Machinist/GM in the manufacturing industry. Kurt started teaching at NTMA , part time, for the Advanced Inspection class, and then In 2007, Kurt became a full time instructor for the MMT course at NTMA. In 2012, Kurt become the Director of Training.

    German Gomez


    German has 20 years of industry experience. He currently works for a large aerospace tooling company where he does project planning. He has over 15 years of 5-axes CNC machining experience with lathes, mills, and VTL’s, in addition to several CAD/CAM systems. His family emigrated from Mexico City when he was 17-years-old, and in order for him to graduate High School he had to join an evening school program where he not only received enough credits to graduate on time, but also obtained two certificates: one as a conventional set-up person, and another one as a junior CAD draftsman. After many years of working as a machinist during the day, completing Machine Tool Technology courses at the local community college at night, and becoming an American Citizen, he landed a job as a Manufacturing Engineer where he loves what he does and makes a good living. After successfully completing a Mastercam course at NTMA sponsored by his employer, he joined NTMA as an instructor, not only because he loves to teach, but also because he feels this is the best way to give back to an industry that has given him so much. He would encourage you to join NTMA and become a machinist too. This will give you the skills needed to make a good living, and also the satisfaction to use your creativity to make great things. See you in class!
