About our Founder: Matt Aatai started building for clients and contractors in the early 1980s. He realized the process of construction from first shovel in the ground to final sale, was something that brought a new chance and new challenge at every step. Matt started his own construction business in 1985. He continued building for clients as the prime contractor on jobs that ranged from government and civil engineering work to large master planned communities and institutional grade facilities. Each project came with its own unique set of demands and lessons. Matt took those hard earned opportunities and started the first of the Seawest family of companies, Seawest Investment Associates LLC in 2000. Fifteen years later and the firm that he has spearheaded and guided with a patient, effectual expertise and a conservative growth strategy has become a dynamo in Seattle area development and investment. With currently over a million square feet of real estate in Washington and still growing, the best is yet to come.
