“O’Neil Securities gives us the platform to bring together event-driven expertise, research, and collaboration in a way that can deliver real value to institutional clients.”

‍
I joined William O’Neil Securities because I saw an opportunity to build our Event Driven and Risk Arbitrage business on a broader platform. The firm gives us the ability to combine event-driven sales and research with the resources of a growing organization, collaborate across different areas of the business, and introduce our capabilities to clients who may not yet know O’Neil Securities. Just as important, the firm’s commitment to putting clients and value-added service first is very much aligned with how I have approached my career.

My goal is to help make O’Neil Securities a leading destination for event-driven clients and for other institutional investors looking for differentiated market color, research, and idea generation. I have spent close to 30 years in event-driven investing and advisory work, on both the buy side and sell side, and that experience has exposed me to a wide range of transactions, market environments, and client needs. I believe that perspective, along with the relationships and market knowledge I have developed over the years, is one of the most important things I bring to the role.

Before joining O’Neil Securities, I worked in senior event-driven sales and advisory roles at Stifel, Oscar Gruss, Cantor Fitzgerald, and Dominick & Dominick. Earlier in my career, I managed and analyzed merger-arbitrage and event-driven investments at firms including Weiss, Peck & Greer, Searock Capital Management, and Richmond Capital Management, and I also co-founded and managed an event-driven hedge fund. Having been responsible for investing as well as advising clients has given me a practical understanding of how ideas are evaluated, positions are structured, and risk is managed.

I earned a BA in Economics with honors from The Johns Hopkins University, where I was elected to Phi Beta Kappa. My interest in finance began even before college through summer internships, and I started my career at Bear Stearns as an OTC market maker before moving into merger arbitrage. Today, one of the biggest opportunities—and challenges—is introducing new accounts to O’Neil Securities and showing them how our platform, research, and event-driven expertise can support their investment process.

Outside of work, most of my time isspent with my two children, ages eight and 10. I enjoy sports and try to stay as active as I can, including golf and basketball, often with my kids. Music is another interest, and family remains the center of my life away from the markets.
