On the banking and credit transaction front, Houston’s Matthew Einbinder is the main contact in the practice, while New York-based Brian Chisling concentrates on federal and state regulatory issues. Other key practitioners in the group include Houston-based buyout and capital raising expert Shamus Crosby, and transmission and distribution specialist Javad Asghari, who is based between New York and Los Angeles and joined the team in April 2024 from Milbank.
