Get to Know Us

We come from a variety of backgrounds, but we all share a passion for American manufacturing. We are growing, and looking for people to join us who are passionate about applying technology to the art of machining to deliver the best possible customer experience.

Executive Chairman

Andrew Hennessy

Andrew is a co-founder of American Precision Technologies, and spends most of his time scanning the market for the next set of capabilities that we can add to better serve our customers.

President -- Concept Components

Jim McGuigan

Jim founded Concept Components in 1989, and he joined forces with American Precision Technology in 2024 to enable continued growth and employment for his team while starting succession planning for himself. If you visit the facility on Long Island, you're likely to find Jim with his head in a machine, solving a problem so that the customer never has to encounter it. When not in the shop, Jim enjoys patronizing his favorite restaurants or leading his granddaughters on adventures and hijinx.

Co-founder, board member

Jonathan Slonim

Jonathan is a co-founder of APT, and can frequently be found reading articles in Practical machinist and looking for the best ways to increase shop efficiency. He has been trying to learn Mazatrol, but the milling department lead still won't let him touch a program without careful oversight. In his spare time, Jonathan likes to read, hike, and ride bikes with his wife and two young daughters. 

Actively Acquiring Exceptional Shops

American Precision Technologies started out as an idea: what if we could bring together the top shops in the country to provide an unparalleled customer experience? We invest in technology, in people, and in sales and engineering infrastructure to make sure that if a part leaves one of our shops, it has the APT seal of approval.

We started in 2024 with our first shop, and are currently seeking additional shops focused on medical, aerospace, and commercial parts. There are 30,000 shops in the country, but we (and our customers) know that some stand out far above the rest.

Criteria: 

  • >$2 million EBITDA or >$10 million revenue

  • Significant annual investment in new equipment to stay at the forefront of the industry

  • Management team on-site seeking to stay with the business and grow

  • US-based 

Capabilities sought: 

  • Milling and turning

  • Swiss turning

  • Wire EDM

  • Additive manufacturing
