American Precision Works is a clean-slate Philadelphia machine shop founded by longtime manufacturing operators Matt Bruner and John Celley, who chose to build a modern company rather than inherit a legacy operation. The small, people-focused team serves engineers whose work leaves little room for error, with a particular focus on complex small parts and clear, digital communication from prototype through production.
