What do you focus on?

For over twenty years, I have represented companies of all stages in the technology, consumer, life sciences and manufacturing verticals, as well as the venture and private equity funds that invest in them.

I enjoy a trusted advisor relationship with leading management teams and investors.

What do you see on the horizon?

With respect to the current dealmaking environment amid the coronavirus (COVID-19) pandemic, we’ve seen little in the way of a consistent theme—the market has not moved in a monolithic way.  Overall, volume is down—but we’ve had processes continue to move forward, while others have paused. Given the otherwise robust start to 2020, everyone is generally optimistic that when some level of normalcy returns to the market, it will result in a few strong quarters for dealmaking.

Federal Bankruptcy Litigation

Represented private equity firm in multi-state litigation filed in the Federal Bankruptcy Court for the Central District of California, defending the client against claims for breach of fiduciary duty.  The highly contested and complex case revolved around the client’s investment in a distributor of medical devices that filed for Chapter 11 bankruptcy relief.  The litigation was commenced in the bankruptcy court by the Creditors’ Committee, and it eventually involved concurrent proceedings before several federal district court judges.  By vigorously contesting the allegations at every stage of the proceedings, and aligning the client’s defense with other co-defendants, a very favorable settlement was obtained and the claims were ultimately dismissed with prejudice.

  • Number Nine Visual Technology Corp., a publicly-held developer and manufacturer of graphics boards and a proprietary internet appliance, in its Chapter 11 case in which the company successfully accomplished the sale of its technology on an expedited basis.
