This review is from a potential client who consulted with this attorney.
| Consulted Attorney
I consulted Attorney Hadas' office on an important personal matter, half expecting anyone to even return my call. What I found was a lawyer with an outstanding listening ear and remarkable compassion. In addition to providing sound legal advice, Mr. Hadas gave me the time and due consideration which set him apart from the typical law firm. How wonderful to see empathy and legal prowess to go hand-in-hand.

| Hired Attorney
Thorough and effective representation with a passion
Attorney Hadas helped me win my civil case after being falsely accused by Atty Edward A. Obrien and Atty Christopher Cercone. As a Paralegal with some experiences, I thought it was a piece of cake until I got lost in the process of the rules... Attorney Hadas came along like "David against Goliath," took time to catch up with the case with several meetings, going through stack of documents, understood my contention, sought my demands and took up the case. I've worked with several other corrupt Attorneys who took money then plan a withdraw for justified reasons, but not Attorney Hadas. He was more focused on liberating me from false accusations.

Working with David Hadas
I am an attorney, and I have chosen David Hadas to represent me in a case involving new legislation and areas of first impression in this legislation. I have found Attorney Hadas to be attentive and legally informed in a fast-changing legal scenario under newly-issued Appellate decisions regarding this legislation. He has demonstrated superior abilities in factual and legal analysis in complex matters, and is able to brilliantly synthesize discussion of these issues in his legal writings. In dealing with clients under duress, Attorney Hadas is calm, logical and persuasive; as he is in court appearances and with the opposition, smoothing the path as he works diligently for his client. I would not hesitate to recommend Attorney Hadas for representation in any area he chooses.

Experienced and trustworthy lawyer
We had to take legal action against a company that decided to not pay our owed fees. He was very responsive, very knowledgeable and walked us carefully through the process. Throughout the ups and downs of this legal process, David always remained calm and confident. He was aggressive enough with the other party to move things forward, but always remained professional and provided great guidance on next steps. I can't disclosed the outcome, but it was very positive for us. I would definitely hire David again.
