sustainable design & construction
A&D Companies, Inc. is a San Diego based premier General Contractor.

A&D Companies, Inc., was founded in San Diego by President and CEO Andrew R. Otero whose focus on maintaining a position as a premier general contractor is the same today as it was in 1988:  Provide consummate customer service that reflects A&D’s deep-rooted principles of honesty, integrity, and dependability, while offering accurate and competitive pricing. These "old-fashioned" values are coupled with trend-setting technologies utilized by some of the best trained, experienced, and forward-thinking professionals in construction. After all, in order to work for the best A&D must offer the best—seasoned expert personnel, inventive approaches, industry-leading technologies, and value-added services.

For nearly three decades A&D has served many of these "best clients" in a variety of market segments across 27 states, on the U.S. island territory of Guam, and as far reaching as West Africa. While A&D doesn’t claim to be “all things to all people,” the company does offer a diverse, evolving set of services—including solutions-oriented construction management, pioneering design-build methods, sustainable innovations, and strategies to enhance estimating and scheduling efficiencies—to clients in both the public and private sectors.

Creating a Culture of One
With an unwavering commitment to the customer and hiring like-minded professionals with the same passion for service, A&D’s impeccable reputation for going above and beyond has earned the firm a 95 percent repeat client rate. The company’s loyal following is reflected in consistently receiving formal evaluations of “exceptional” for their outstanding service.

Always taking a collaborative approach and empowering people to be solutions- oriented, A&D’s ability to communicate within the team—and have everyone on the same page with complete buy-in to common goals—has resulted in a seamless organization and real sense of community between the client and virtually any A&D employee. Whether providing solutions that inspire new nationwide standards, improving the functionality of highly-sophisticated systems, or working in partnership to develop cost- and time-saving strategies, A&D is always ready to go the extra mile.
