Highly Recommended
Factor Law gave me options in my bankruptcy case including some very complex and technical issues. Bill and his team were tenacious, knowledgeable and compassionate throughout the process. He was the right choice from the first meeting!

Professionalism with a Heart
Mr. Factor and his staff worked tirelessly and sacrificially to help our non-profit navigate the mires of legal proceedings of fraud against the organization and subsequently, bankruptcy. Throughout the years of representation, Mr. Factor has shown time and time again sensitivity and commitment to the cause and mission of the organization, while juggling all the legalities in our complex case. Our case is dismissed with the Corporation intact, albeit a little shaken.

Outstanding Law Firm
The best decision we ever made was retaining the Law Firm of William Factor to represent us in a very complicated Ch. 11 Bankruptcy Reorganization. He was with us every step of the way. His courtesy and consideration and timely and thoughtful responses to our questions were remarkable. He has a brilliant legal mind for analysis and always provided excellent legal advice and alternative choices where appropriate. Handling an unrelated matter, we were extremely impressed with his general litigation staff. The result was excellent. Highly recommended.

Great lawyer
Great lawyer. Extremely knowlegable in the legal and practical aspects of the law and the situation. Bill was most interested in resolving the problem rather than litigating the matters and making representation more costly. A true advocate and great professional. The best lawyer I have used.
