      "description": "McDermott Construction, a family owned business, was established in 1975 by General Contractor Brian J. McDermott. After completing his service with the US Navy it was his dream to create a company built on the highest quality craftsmanship and standards. His son, Sean B. McDermott, believed in the family vision and together they have made that dream a reality by working closely together. McDermott Construction has evolved as a powerhouse company that specializes in everything from renovating a small bathroom to custom-built homes. Serving the L.A and Ventura counties for over 40 years, McDermott Construction is known for personal relationships, being reliable, and providing quality work.",
