Allan H. Cohen
Partner / Office Managing Partner, Long Island
Introduction
Allan Cohen, office managing partner in our Long Island office and a member of the firm’s Policy Committee, represents a variety of companies, ranging from large and middle-market companies engaging in mergers and acquisitions to closely held and family-owned businesses engaging in transactions or otherwise in need of outside legal advice to technology-based startups organizing new business ventures and raising capital.
My focus
I maintain a transactional and general business law practice, adept at handling my clients’ varied business needs and providing the type of business-minded advice 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 healthcare, medical device, life sciences, food, consumer products, and insurance. Over my career, I have closed well over 200 M&A transactions.
Emerging companies also represent a significant part of my practice, including biotech, medical device, and other technology-based companies; I assist with business formation and organization and seed, angel, venture capital, and private equity financings. Much of my work is for “serial entrepreneurs” who have exited prior businesses and are starting their next ones.
Looking ahead
Technology-based and other companies that flourished during the pandemic will provide a hedge against economic uncertainty and fears of a recession. The greatest success will go to entrepreneurs that identify where the post-pandemic business world will be and get there before their competitors.
