He was admitted to the bar in 1977. In September 1995, he was the subject of a random compliance audit by the Office of Attorney Ethics (OAE). The preliminary report indicated that Blumenstyk had knowingly misappropriated client funds between December 1994 and June 1995. A demand audit confirmed the first findings and a formal ethics complaint issued. The District Ethics Committee and the Disciplinary Review Board concluded that Blumenstyk had knowingly misappropriated client funds and recommended disbarment.
