Jeffrey joined the family Business, carpet and rug manufacturer Aladdin Mills, in 1976, after graduating from the University of Denver. Lorberbaum held a number of leadership positions, eventually serving as Vice President of Operations from 1986 to 1994. In 1994, Aladdin merged with Mohawk Industries, which had gone public in 1992, creating one of the largest flooring manufacturers in the United States - and his Father became Mohawk’s largest shareholder. Jeffrey and Alan Lorberbaum then joined Mohawk's Board of Directors. In 1995, Lorberbaum became President of Mohawk; and, in 2001, he became CEO. Since then he has grown the company to $5.8 billion in revenues (2012) partly through acquisitions that expanded the scope of the company into hard surface flooring (ceramic tile, laminate, hard wood) and provided access to new geographies. In 2002, Lorberbaum orchestrated the $1.8 billion purchase of Dal-Tile of Dallas making Mohawk the world’s largest tile-maker. In 2005, Mohawk purchased Unilin, a Belgium-based maker of laminate flooring and MDF board (a composite used in do-it-yourself furniture) for $2.6 billion.
