Dr. William J. Mack Becomes 25th President of the Society of NeuroInterventional Surgery

FAIRFAX, Va.— Dr. William J. Mack, a neurointerventionalist at the University of Southern California (USC) in Los Angeles, became president of the Society of NeuroInterventional Surgery (SNIS) during the organization’s 17th Annual Meeting earlier this month. As president, Dr. Mack will lead SNIS’ initiatives to advance excellence in minimally invasive neuroendovascular care. Dr. Richard P. Klucznik, a neurointerventionalist at Houston Methodist in Houston, Texas, becomes the SNIS immediate past president.

“The field of neurointervention is flourishing, driven by the brightest minds who continue to adapt and innovate to meet the challenges of a rapidly changing world,” said Dr. Mack. “I look forward to both the challenges and opportunities to come in the year ahead and promise to drive forward SNIS’ mission of championing patients and improvements to systems that will help them receive timely and appropriate care.”

In addition to his clinical work at USC, Dr. Mack is the Principal Investigator and Director of the Cerebrovascular Laboratory in the Zilkha Neurogenetic Institute. He has received numerous local, regional, and national grants to support his research efforts. His scientific interests focus on translational efforts to treat ischemic and hemorrhagic stroke, and his laboratory investigations concentrate on the pathophysiology of stroke and inflammatory modulation. Using the information and experience gained in the laboratory, Dr. Mack is working to develop new technologies, techniques, and therapies to directly improve the clinical care administered to stroke patients.

Dr. Michael Chen, a neurointerventionalist at Rush University Medical Center in Chicago, is now president-elect of SNIS, and Dr. J Mocco, a neurointerventionalist at Mount Sinai Hospital, has been elected vice president. The SNIS board of directors will continue to advance the specialty of neurointerventional surgery through initiatives such as the SNIS Foundation, the Get Ahead of Stroke campaign, and the Journal of NeuroInterventional Surgery.
