While the real estate recovery has been slow to positively impact many firms, Taylor Johnson client MACK Companies has been growing by leaps and bounds - increasing revenue by 1,100 percent over the past five years, to be exact. That exceptional growth landed the firm a spot on this year's "Fast 50" list by Crain's Chicago Business, which notes the fastest-growing businesses in the Chicago area. In fact, MACK Companies ranked 12^th, and was the top-ranked real estate firm on the list. In addition to its successful single-family rental property business, the firm is poised for continued growth through its construction, commercial and brokerage businesses.
