As the managing partner of the Prell Organization, he believes that the methodology should be driven – not by the researcher’s area of expertise – but by the nature of the issues being researched.  That is why he feels equally at home conducting qualitative and quantitative research, either online or offline.

Some of his clients include: CitiMortgage, AAA Auto Club, Edward Jones Brokerage, Emerson Electric, St. Louis Rams, Express Scripts, and the St. Louis Post-Dispatch.

Mr. Weitzer has also been Director of Research at Kerlick Switzer Johnson Advertising, conducted surveys for KMOV-TV, the CBS-affiliate in St. Louis, taught marketing research at Southern Illinois University-Edwardsville, was on the staff of Congressman Richard Gephardt, and directed polling operations for St. Louis Mayor Vincent Schoemehl.
