Mergers and Acquisitions Law

Spinning circle Big letter B

“The art of being a business lawyer is protecting my clients’ interests—balancing risk and opportunity—while achieving their business goals."

I am all business, for all businesses. In my thirty plus years as a business lawyer, I have handled virtually every issue affecting or arising from the business lifecycle. Whether you have an existing business or plan to launch one—regardless of your industry—I’m here to help you.

Clients rely on me to spot issues, assess and minimize risk, develop creative solutions, and provide pragmatic advice to execute a strategy for achieving their goals. My depth of experience ranges from reviewing and drafting all manner of contracts to negotiating complex mergers and acquisitions, and advising on wealth management issues. I have dealt with business issues from the client’s chair, having worked in my family’s graphic arts and advertising agency early in my career.

I am grateful to possess the unique left brain, right brain combination of logical and creative thinking. I can connect concepts that aren’t necessarily related, see trends and patterns, and identify the pertinent issues to find the best solution for each client’s situation.

I am also proud to serve on the firm’s management committee and to have been the firm’s President from 2008-2019. It’s exciting to be a part of a collaborative team focused on a common goal: providing smart solutions to clients.
