What do you focus on?

Mergers & Acquisitions

I advise buyers and sellers in a variety of merger and acquisition transactions, including stock purchases, asset sales, mergers, divestitures and reorganizations. I’ve represented a strategic buyer in multiple acquisitions and have experience in complex M&A structures. A notable recent transaction involved the reorganization of our client, followed by its merger with a second company and simultaneous sale of assets to a third company.

Private Equity

I represent private equity investors in connection with their portfolio company investments and exits. I also advise portfolio companies of private equity clients with respect to their acquisitions, divestitures and corporate governance matters.

Outside General Counsel

On an ongoing basis, I act as outside general counsel to companies by advising on general corporate matters and a wide range of commercial agreements, including services agreements, licensing agreements and domestic and international joint ventures.

What do you see on the horizon?

I’m seeing a growing number of parties to acquisition agreements obtain representation and warranty insurance policies in order to allocate risk to third-party insurers and facilitate closing transactions. We can help our clients take advantage of this approach while navigating pitfalls.
