About Us



Signature Signs is owned by Dana and Dorena Costa.  We opened our first 1000 sq ft shop in Dartmouth Massachusetts on September 10, 2001.  We relocated 2 additional times in the same plaza to larger storefronts.  After several years we once again needed more room to accommodate our growth. So after 14 years in Dartmouth we moved 5 minutes away to Westport MA.  We now have a 5000 square foot facility, with 4 garage bays and a large yard for storage. 


We have a team of professionals that work with you through the many steps it takes to create a sign.  Dana leads the  installation, repair and maintenance team, while Dorena, leads the inside staff of design and fabrication.  We are extremely lucky to have a great team that works well together and can do many different tasks which is essential with a smaller sign company. 


We are a full service sign company.  We do everything from design, permitting, fabrication, installation, maintenance and repair.
