Mark has been litigating high stakes matters for more than 30 years.

In recent years, he has obtained dismissal of securities claims asserted against former directors of a bank holding company; persuaded a district court to dismiss a shareholder derivative action for failure to make demand on the corporation’s board of directors, and to dismiss a subsequent shareholder derivative action following refusal of demand by a special committee of the board of directors; and obtained a defense verdict and an award of full attorney’s fees on behalf of an investment advisory firm that allegedly misrepresented the nature of investments sold to a national bank.

Mark is an experienced trial lawyer, having tried numerous cases in federal and state courts and in arbitration.

Mark maintains an active commitment to pro bono work. After 11 years of litigation, he persuaded a federal court to grant a habeas petition and release a client who had been sentenced to life imprisonment. For the past 15 years, he has been representing a client on death row in Mississippi.
