Business Law and Litigation

"Truly Impressive"

"Timothy Zerillo, along with his associates and staff, will forever be held by me in the highest regard. Tim and his firm represent the pinnacle of service and legal expertise. When I was sued by a former business associate, Tim immediately put me at ease and assured me that every course would be explored in pursuit of a resolution. He has exceeded every expectation - I cannot say enough good about Timothy Zerillo and his team of legal professionals."
