Hollis Line Machine Company was founded in 1962 in Hollis, NH by John Siergiewicz Sr. Having worked for the areas largest manufacturer of its time, John began his own business in the barn on the family's 80 acre farm located on the town border between Hollis & Amherst N.H., hence the name Hollis Line Machine Company.

The family business was joined by John Jr. in the mid 1980's after formal training at The New Hampshire Vocational Technical College in Nashua and also learning the trade at various manufacturing companies in the region. The company soon outgrew its location in the barn and an 18,500 square foot facility was constructed on a five acre portion of land on the farm. In 2007, we purchased a new facility in Milford, NH that enabled us to expand our capabilities, facilities and services. We have now made the Milford location our permanent machine shop home.

Our Milford Facility

The facility consists of 50,000 square feet dedicated to manufacturing and fabrication and is located on thirteen and a half acres. Everything here runs smoothly and efficiently.
