FOSTER & ASSOCIATES, INC. Founded in Portland, Oregon in 1981 and originally focused on the insurance needs of our clients, our business model has long since grown to include nearly all facets of financial, retirement, and estate planning. With our main office currently located in Wilsonville, Oregon, Foster & Associates has representatives throughout Oregon and Washington. Our advisors recognize the individual needs of our clients and help them "road map" a course from where they are to where they want to be.
