Hollis Line Machine Company

Hollis Line Machine Company was started in the early 1960's by John Siergiewicz Sr. Having worked for the areas largest manufacturer of its time, Mr. Siergiewicz began his own business in the barn on the family's 80 acre farm 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 learning the trade at various manufacturing companies in the region. The company soon outgrew its location in the barn, and constructed a 18,500 square foot facility on a five acre portion of land on the farm, where the company now operates. Hollis Line Machine Company specializes in the precision machining and fabrication of Stainless Steel and caters to prototype work from the Research & Development field.
