Biographical / Historical

The Warren Group, Inc., led by Willard C. Warren established itself in the newspaper business in New Haven, Connecticut in 1882 with the publication of The Commercial Record. The firm provided news and public record information and data to clients. Warren established The Banker in Massachusetts just after the turn of the twentieth century. In 1902, Warren purchased a rival newspaper and consolidated both newspapers into Banker & Tradesman.

Warren's son, Keith F. Warren joined the firm in 1918 and the business expanded into the book and trade magazine publishing industry. After the Great Depression and into the 1930s the business shrank and survival was paramount. After World War II, Keith Warren's son, Timothy M. Warren joined the firm and prospects improved, especially in the 1970s. In 1973, Timothy M. Warren's son, Timothy M. Warren, Jr. joined the firm making him the fourth generation Warren to be involved in management.

The late 1970s and 1980s saw rapid expansion of the Warren Group. The company harnessed computing power in the office and began offering a wide variety of new products. An even larger variety of products were offered after the rise of the internet, which has established The Warren Group as one of the most respected real estate and financial information reporting firms.
