New York- and Florida-headquartered bank National Holdings Corporation has appointed Donald Runkle as executive vice president and chief supervisory officer of National Securities Corporation and National Asset Management. 

The bank also appointed Robert Bowman as managing director and national sales manager, and Thomas Kowalczyk as managing director of investment solutions of National Securities Corporation and National Asset Management, the firm said in a statement.

Previously, Runkle was the director of consulting services with Freeman Mathis & Gary, and the regulatory compliance director for Coordinated Capital Securities.

"This is evidenced by the caliber of leadership and experience in the new additions to our team. Each new member brings a unique skill set that we believe will be highly impactful to the continued success of our firm. I look forward to closely working with each of them as we continue to grow and build the National brand into a leader in the industry.”
