Company History

Stephens Precision began in 1981 as a tool room for the aircraft industry with close ties to many of the R&D and engineering firms spawned from Dartmouth College in Hanover, New Hampshire. We are a Woman-Owned Small Business with approvals from a number of Aerospace prime contractors who benefit from the experience of our President, who has a background as a pilot, aircraft owner, and A&P mechanic. The second generation has joined us with a formal engineering background  and experience in larger companies and, as General Manager, has streamlined and modernized many of our processes. Our key to success has been control of our processes yielding quality, accuracy, and consistency. Our clients appreciate our flexibility in working with them as partners as well as our attention to all aspects of the job from checking details of the contract to the accuracy of the final count and care in packaging of the parts for shipment. We are proud of our clean, air-conditioned facility and temperature controlled Quality Control Department in Bradford, Vermont and welcome you to visit us.
