Thomas Reed
I engaged William Lesser at Cozen O'Connor for assistance with a commercial energy supply contract review for my small business. His background in Energy Law, including the recognition from Best Lawyers, was evident in his thorough analysis of the rate structures and regulatory clauses. He identified several potential liabilities that I had overlooked. However, the experience was mixed. While the legal work itself was solid, there were noticeable delays in receiving drafts, and responses to follow-up emails often took several days. For a straightforward contract matter, the process felt slower than anticipated. Mr. Lesser is clearly knowledgeable, particularly in the energy sector as his profile suggests, and I felt the final product protected my interests. The outcome was satisfactory, but the client service aspect—managing timelines and setting clear communication expectations—could be improved to match the quality of the legal expertise.
