This review is from a person who hired this attorney.

Exceptional attorney committed to providing outstanding legal service.

Bill is an exceptional and dedicated attorney who exceeded my expectations and earned my trust and respect. A compassionate professional who took the time to explain the process, answer all my questions and reassured me that I was in best hands possible. He is committed to providing each client with... outstanding legal representation at reasonable rates. For me, Bill completely redefined my notion of integrity and competence in the legal services industry. If you are in need of legal services and you want a great attorney who will fight for you, then I highly recommend William Mazur.

Great Communicator, Very Responsive, Fantastic Attorney

Bill instantly gave us the reassurance that was needed in a stressful Tenant/Landlord case from the initial consultation. He put our worries at ease with clear communication and responded swiftly and accurately with the details for our case. I would not hesitate in recommending his services to anyone... who has a situation like we did as he knows the RLTO inside out. Responsive, knowledgeable, diligent and most importantly, effective. This is the go-to lawyer in Chicago in my opinion. Highly recommend.

Help in evicting my tenant

Bill was very thorough and walked me through the process with what to expect. He was timely in acting and appraising me of the actions and next steps. I would definitely use him again if the need arises in the future ( although I hope not to need his services).

Great Attorney for Eviction

Bill was great at handling my case with a difficult tenant. He explained the process to me thoroughly and was reasonably priced. Very prompt in answering calls and emails, he handled the case flawlessly.

Relationship: Worked together on matter

"Bill is a fantastic attorney. Bill and I worked together on a complex business matter for our client that included commercial, customs, and judgement debtor issues. Bill's help was crucial because some of the legal issues were in a jurisdiction that my office did not have a license. Bill's warm and patient demeanor helped walk our client through the matter and ultimately resolved the matter in a manner favorable to our client. I would highly recommend Bill to anyone."

"Bill and I have networked as colleagues for a while. Recently, however, I contacted him as a 'client'. Actually a consultation regarding an L/T situation for my elderly mother. Bill was patient, understanding, knowledgeable and wise in his counsel. I'm glad I have him to turn to myself and to refer my clients to."

"I fully endorse Bill in the area of landlord-tenant law. He has a clear grasp of the law and is able to provide insight into how a case may play out in court given his extensive litigation experience as well. Bill is also a pleasure to work with and treats his clients with the utmost respect. I would (and do) highly recommend his services to any landlord or tenant needing services in the area of eviction."
