After ten years as an insurance and business consultant, during which time he was also an active volunteer on numerous political campaigns in New York and California, he entered college with the deliberate intention of becoming a Political Campaign Consultant. Under the guidance of Dr. Joel Fisher, he developed a curriculum of studies designed to provide him with the foundation for this new career. He is, therefore, the first professional political campaign consultant in the industry. At that time, no other college or university offered a program for Political Campaign Consultants or managers.

Following his academic training, he apprenticed for a year with Joe Cerrell, Cerrell Associates, Inc., Los Angeles, California, working on campaigns in Beverly Hills and Los Angeles. This experience provided valuable "on the job" training in campaign techniques, especially fund-raising, public relations, and free media communications. Later, he continued his apprenticeship with George Young, George Young and Associates, Inc., Los Angeles, California. For two years, he managed campaigns in California, Michigan, and Pennsylvania. While with Mr. Young he developed an in depth knowledge of media production and placement, direct mail campaigns, and the dynamics of campaign management.

In 1975, he founded Campaign Management Associates, Inc. (CMA), a non-partisan political consulting and management firm in Los Angeles, California. Determined to provide a "one stop shop" for candidates in order to help reduce a campaign’s overhead costs, he continually expanded the range of services provided. For four years, he continued to work on various campaigns around the country in Washington State, Iowa, Wisconsin, Florida, California, and other parts of the country.

It was during this period that Mr. Guzzetta developed and produced VERITAS, an integrated, voter identification and targeting program. VERITAS assisted candidates and Party Committees with the coordination of poll results, verifying data input, generating useful reports, maximizing the value of direct mailings, the management of phone bank and precinct operations, fund-raising, and with the development of appropriate manuals for campaign staff and volunteers.

In 1979 Mr. Guzzetta moved to the Washington, D.C. area and formed the political consulting firm of S. J. Guzzetta and Associates in Alexandria, Virginia. During this period, he consulted on campaigns in Maryland, Virginia, Delaware, Indiana, Texas, Louisiana, North Carolina, Illinois, California, Guam, and Michigan. In addition to his campaign consulting, he lectured, conducted campaign seminars, and did research and analysis in a constant effort to improve and refine the basic techniques and procedures used in campaign management. In 1988, in addition to his other activities, Mr. Guzzetta became the publisher of Political Publications and was responsible for developing its marketing and administrative program.

Mr. Guzetta has been a frequent lecturer at the North Carolina Institute of Political Leadership, the Ted Sorensen Institute of Political Leadership in Virginia, the National Campaign Institute, Campaigns and Elections Seminars, Florida State University, the Graduate School of Political Management in New York City, the Campaign Management College, numerous national, and state party seminars, the American Association of Political Consultants, the American Medical Political Action Committee, and the Indiana Chamber of Commerce. He has participated as a co-sponsor and lecturer at the Campaigns and Elections Seminars in Hungary, Czechoslovakia, and Poland. He has also done lectures and provided political assistance to political parties in Taiwan and Brazil.

He wrote the 1st edition of The Campaign Manual in 1981. Later he wrote two companion books called The Campaign Strategy and The Finance Manual. The Campaign Manual 6th Edition, is an updated and revised composite of all three books.
