His son Ted followed in his father's footsteps and expanded the firm beyond traditional audit and tax services into management efficiency and technology consulting as well as reporting and compliance advisory services for SEC-registered companies. Ted also established the firm's West Coast presence by opening its San Diego office.
The 1970s saw J.H. Cohn's scope expand considerably. It also brought the founding, in 1977, of Reznick Fedder & Silverman, in Washington, DC. The small firm, which specialized in real estate, quickly outgrew its early offices, relocating to Bethesda, Maryland and opening an office in Baltimore.
The establishment of the federal low-income housing tax credit program in 1986 dramatically changed the trajectory of Reznick Fedder & Silverman. Quickly realizing the opportunity the program presented to its real estate clients, the firm soon established itself as a national leader in the affordable housing arena. This growth allowed the firm to expand geographically, offer services in valuation and transaction advisory, and establish industry practices in financial services, technology, non-profits and other areas.
Beginning in the 1990s, both J.H. Cohn and Reznick Fedder & Silverman—eventually renamed Reznick Group—went through a period of intense growth, acquiring smaller firms and establishing themselves as two of the country's major independent accounting firms. In 2012, the two firms, recognizing their similar cultures and the complementary nature of their capabilities and geographic presence, combined to create the 11th largest accounting firm in the United States.
Today, CohnReznick has offices from Boston to Los Angeles (as well as in the Cayman Islands and Chennai, India) and provides a complete range of services to both public and private companies across numerous industries. While the firm has grown greatly since its beginnings, its central philosophy of client service continues to this day.
