Andy is the owner and president of Dielmann Sotheby's International Realty. At the very young age of 21, Andy's father, Harold Dielmann, encouraged him to go into real estate. Harold had dabbled in real estate over the years with investment properties and knew this would be an excellent career for his son. He urged Andy to be his own boss and start his own company. After graduating from the University of Missouri in May of 1976, Andy received his salesman's license. Shortly thereafter, in June of 1976, he passed his broker's license, and in August, Andy incorporated Andrew W. Dielmann & Company.

Andy's vast knowledge of the industry and the St. Louis market has led him to be a recognized expert in residential real estate in our area. With an ever-growing company comprised of the most experienced and knowledgeable agents in the area, he is proud to support high-touch, personalized service to both buyers and sellers at every price point.
