Our History

Brefrank is a Florida-based real estate company founded by Leo Jacobsohn in the 1950s. The business was later managed by Leo’s sons, Harold and Ralph, and today remains a family enterprise led by Gary Koolik and David Weinstein.

Since its inception, Brefrank has participated in the development of real estate projects with an aggregate value of more than one billion dollars. In addition to extensive developments in Florida, the firm owns and manages properties in Minnesota, Illinois, Massachusetts, Alabama, Texas, and the United Kingdom.
