Wonderful, Dedicated, Attorney

I was recommended to Mr. Dieguez through a professional contact I have known for several years. I had contacted several other attorneys who didn't even take the time to call me back within an acceptable time. My contact said that Mr. Dieguez was the best in his field.Upon working with Mr. Dieguez t...his was proven, on several occasions. He is extremley responsive and very genuine. I was able to tell that he cared about me as a person not as a number. He took his time in our initial telephone call and seemed to have a real passion for the clients he worked with. He was extremley knowledgeable in many areas of the profession most importantly employment laws. He worked diligently to ensure my case was handled with the utmost professionalism & knowledge. I would hihgly recommend Mr. Dieguez to any of my family, friends, and or professional acquaintences.

Professional, knowledgable, aggressive attorney who gets results

Mr. Dieguez is in one word - awesome. He is a knowledgable attorney, with the aggression, and know-how to get the results his clients hope for. I HIGHLY, HIGHLY recommend him.

NOT the kind of attorney you need on your side!

I thought I would find that the AVVO review was enough to help and good enough to aid me in finding a good workman's Comp lawyer. But gush, I was damn wrong. And that's why this review is important for me to write. I had the most HORRIBLE experience with this attorney "Marcelo Dieguez", I am stil...l in the state of shock for the way I was treated by Marcelo! I went to his office for consulting and possibly retaining Marcelo for my case. He briefly spoke to me and left me in the room with a pile of documents and forms to sign. I started reading them before signing, as is my RIGHT to make sure I understand everything in the documents that he put in front of me before signing them. Among those documents, I found some contradictory statements in his fee agreement and his duties with what he had promised he will do for me. There was a clause about his commission which he had told me would be %15 but in his fee agreement, it was saying it could go to %33!!! Also, there was another clause saying that he would send a non-lawyer representative to the hearings instead of himself!!! So when he came back to the room I asked him about those clauses and needed some explanation, as anybody else would, but instead of answering my questions, he suddenly throw the documents at me and got up and said, you know what, I don't think that I am the right attorney for you, your case is not worth my time, and while he was leaving the room, he said: no wonder you got fired...This must be the reason for them to fire you!!! When you have a work issue and you feel your company has let you down as a person, it's time for you to look for professional help, the last thing you need is an attorney that has no respect for his clients. This man definitely is NOT the kind of attorney you need on your side, he is dishonest, rude, unethical and unprofessional. This guy has no human decency. You should NEVER hire him, even if he works for free!

Dear Anonymous Potential Client, I am very sorry to see this review. As you know, your description of events is completely inaccurate. I pride myself on working really hard on all cases I am retained on and on providing all my prospective and actual clients with my undivided attention. As a mater of fact we spent about 1.5 hours together at my office. Unfortunately, I could not take your FOUR cases against your last TWO employers and for what you believed to be both civil cases and worker's compensation cases. You hired and fired a lawyer within a week, and I was going to be at least your second lawyer in a short period, and I did not want you to have to go through the same fate with my firm. What is accurate is that I did tell you that I was not the right lawyer for you. As I told you, we take cases we truly believe in and pour ourselves into such cases. However, we cannot take all cases that are presented to us. I do wish you the best of luck with all your matters and do hope you find the right lawyer/lawyers. Respectfully, Marcelo Dieguez

Employment and labor lawyer | Nov 07

Relationship: Worked together on matter

"I had the good fortune of being introduced to Mr. Dieguez several years ago by another lawyer in the community, who knew that I was in need of a referral to an outstanding employment law attorney. Since then, I have referred several clients to Mr. Dieguez, and we've worked together with him on a few matters when a client needed both of our services. Without exception, the clients I sent to Mr. Dieguez have raved about his services. He is an outstanding attorney who is highly regarded among other employment lawyers as a rising star. He is not only knowledgeable, but a true gentleman with unquestioned integrity. His advice is not only legally sound but always very practical, taking into account not only the legal implications of the clients' situations, but also their applicable business circumstances. In short, Mr. Dieguez is a lawyer's lawyer. A prospective client can in need of employment law counsel do no better."
