Allan H. Cohen

Allan Cohen is the Office Managing Partner in Long Island. He represents a variety of companies, ranging from large public entities engaging in mergers and acquisitions, to mid-sized closely held and family-owned business, to technology-based startups organizing new business ventures and raising capital.

What do you focus on?

I focus on maintaining a general business law practice, adept at handling my clients’ varied business needs and providing the type of outside counsel that businesses would expect from an in-house general counsel. My clients view me as the “quarterback,” ensuring that not only their business law, but also their employment, litigation, intellectual property, regulatory and other legal needs are met.

I dedicate much of my practice to mergers and acquisitions, including buy-side work for public and private companies, and sell-side work for closely held and family-owned businesses. My M&A transactions involve a wide range of industries, including health care, medical device, life sciences, consumer products and insurance. Over my career, I have closed well over 200 M&A transactions.

I also represent many technology-based startups, including biotech and medical device companies, in the formation and organization of their businesses and seed, angel, VC and private equity financings. Much of my work is for “serial entrepreneurs” who have exited prior businesses and are starting up their next ones.

What do you see on the horizon?

Technology-based companies are going to lead us into the next decade. We partner with our clients in order to help them become market leaders of the future.
