Hoyle Tanner is an engineering firm based in Manchester, NH (USA), with a strong presence across the Northeast including regional offices in five New England communities and southern headquarters in Oviedo, Florida. In July of 2022, we relocated our Massachusetts office to Chelmsford within the Cross Roads at Route 129. Since 1973 we have completed nearly 13,000 engineering projects.
Our 100+ team includes technicians, and support staff with expertise in planning and engineering for civil, structural, water resources, transportation, and aviation projects for municipal, state, federal, and private clients. What sets us apart even more than our expertise is our reputation and relationships within our communities. We live where we work and experience our accomplishments for ourselves every single day.
