WILLIAM P. SENNÉ
President & Owner
William Senné, President and owner of The Senné Company, founded his independent real estate organization in 2009 and has since methodically advanced the firm’s vision, purpose, and principles. Mr. Senné develops and implements corporate strategy across all business units, working closely with the leadership team to continually improve services, grow market share, and have a lasting positive corporate impact.
