The L. H. Sonny Siau Award of Excellence was named after Mr. Siau because service to Mr. Siau’s county and to his fellowman were paramount in his life. Duty, loyalty and honor were the essence of his being. Mr. Siau's motto was to represent the people of South Carolina in a fair and impartial manner while administering tax laws fairly and justly toward all.

Martin Posey was awarded this prestigious award in acknowledgement of his many years of dedication and loyalty to the association and to the people of the State of South Carolina as a tireless proponent of fair property taxation, a faithful friend and comrade, a true statesman – personifying Sonny's passion for excellence in public service.
