The office for the O'Sheas Delivery Service is located in a small industrial park not far from the municipal airport. It's tricky to find the shop because it is hidden behind the Ceramic Floor Supply, G & W Truck and the Line X auto shops. It's accessible by entering the Via de la Vale Road which is behind the shops. It is a moving company that specializes in large bulk mailing of products for businesses in the North San Diego County area. It also works with the US Military at Camp Pendleton to move large-scale equipment and machinery.
