I have a passion for employee rights.  I believe in the ethical practice of law, and focus on obtaining the best results possible for my clients in the shortest amount of time, realizing the stresses and emotional toll of litigation.  At the same token, I believe that some cases have to be tried, and am not afraid of taking such cases all the way to trial.   I pride myself in providing superb legal representation and being accessible to my clients at all times in order to ensure they are fully informed about the progress of their cases.  I have recovered millions of dollars for my clients, while at the same time giving them a sense of justice over unfair circumstances.

 

In my spare time, I enjoy boating, soccer, and above all, spending time with my wife and son.

Passionate and Dedicated Attorney
I have had the honor and pleasure to work with Marcelo over the last 8 years. I have also referred others for his services and initial consultation as well. The message the resounds with each referral or encounter with Marcelo is: Hard Working Dedicated Knowledgeable Driven Professional

Marcelo Dieguez was extremely helpful
I called for a free consultation for an employment issue and spoke to Marcello. I felt confident in my decision to hire his firm after Marcello took the time to listen and to guide me. After 6 months he got me a super result. I would highly recommend.

Excellent Attorney
Mr. Dieguez acted promptly and professionally whenever something pertaining to my case needed to be done. He was also kind and understanding to my situation. When dealing with the other party, Mr. Dieguez defended me aggressively and made it very clear that he was not there to play games, but to come to a prompt and fair resolution in my favor. I would absolutely recommend him to anyone seeking legal help with an employment issue. Should I ever have another legal issue I would even reach out to him for a referral because I trust the kind of attorney he is and can only imagine that he works with and knows like minded attorneys.

GREAT ADVICE -NOT YOUR TYPICAL CREEPY LAWYER
Though our conversation was brief I really appreciated how honest and straight to the point Marcelo was regarding my case. He gave me great advice and reasons to consider both moving forward with a lawyer and without. Jury is still out on which way I'm going but would consider Marcelo all the way.

Knowledgeable attorney, caring follow through
I really needed legal help and contacted other attorneys who were either unwilling to help or lacked legal knowledge. I came across Mr. Dieguez and had a positive experience. He really knew his law, I got the help I needed, and he resolved my problem. I feel like he gave me my life back.

The best employment attorney you can get
Marcelo Dieguez was my attorney that helped me resolved my employment problem with results that were favorable to me. He basically took me out of a very complicated and negative situation, which would have ended pretty badly for me if he wouldn’t have fight for my rights. He took the time to understand the situation and explained the best alternative to resolve it; he also was very straightforward about the legal process. I can move forward with my life and look forward for a brighter future in my professional career. He was very respectful and transparent about the hours he needed to work on my case and careful to no misuse them. I have a bid deal of gratitude towards Marcelo and I will highly recommend him in any employment problem. I agree with others reviews about Marcelo: Hard Working 
Dedicated 
Knowledgeable

Very nice guy. Helped me out when nobody believed in me.
Marcelo Dieguez was my attorney and believed in my case when other attorneys would not take my case. I was very happy with the result. He explained the process to me and was very straightforward about the legal process. He was always available when I called him and was well respected by the other council. I would highly recommend him in an employment problem.

Great Aggressive Attorney
I hired Marcelo to help me with a sexual harassment case after years of taking abuse by my direct boss. He was very supportive, told me how the process worked, and really believed in me. After almost a year of hard work, he got me a great result. But even more, he got my dignity back. Thank you for all the hard work and believing in me.

Marcelo Adrian Dieguez
Having personally dealt with Mr.Dieguez I can recommend him without any hesitation. He is extremely honest, well versed in the laws, prompt, professional, understanding and caring. I would, if the need arose, employ his services again.

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 this 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.

Excellent Attorney. Aggressive, professional, and answered calls promptly.
I was very pleased with their service. Marcelo explained the process to me in simple terms, yet was very aggressive in pursuing my case and defending my rights. I expected the process to last years, but he was able to resolve the case very quickly. The other's side attorney seemed to know and respect both this Firm and Marcelo. Very happy with his work and attitude.

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 still 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!

Response from Marcelo Dieguez September 1, 2020
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 takes 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

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."
