As a Washington Chartered Trust Company our financial activities are regulated by the Washington State Department of Financial Institution’s (DFI). Our work as a Certified Professional Guardianship Agency is subject to rules established by Washington’s Certified Professional Guardian Board, whose members are appointed by the Washington State Supreme Court. Our records are also audited annually by an independent CPA firm.


Since it was founded, Guardianship Services of Seattle has been committed to providing the highest professional standards no matter a client’s unique circumstances or level of need. Our services are aimed at optimizing the welfare and dignity of each individual client. We strive within the authority we are given, to make the best decisions for our clients, and to include our clients and their families as much as possible in decision-making.


As a professional fiduciary, GSS takes its responsibility to act solely for the benefit and interest of the client, and to avoid any potential conflicts of interest very seriously. As both a professional fiduciary, and court appointed guardian, we hold ourselves to the highest standards of care. We feel it is our duty to handle our clients' affairs with the same attention and care we would give our own.

GSS staff include the most experienced Professional Guardians and managers of Special Needs Trusts in Washington State. GSS currently employs ten Certified Professional Guardians.

GSS staff are available by telephone or in person during regular office hours, and are on-call and available 24 hours a day, for emergencies. Click on a staff member’s picture to send email.
