This move presents a great opportunity to work alongside a talented team, advising banks, businesses, family offices, and private investors on corporate finance, investment structuring, and governance strategies. I look forward to leveraging my experience to help clients navigate pivotal decisions and contribute to a firm that values both legal excellence and deep client relationships."
