About Us

With a USC degree and 15 years of carpentry and general construction knowledge and experience, I opened Seaport Windows and Doors in 1991 at 4201 Katella Ave., in the city of Los Alamitos. Back then, it was just my wife Lisa and I, marketing with flyers down the local streets, meeting our neighbors, and selling, installing, servicing, and generally doing it all as a small local window and door store.
