Workers Compensation

Hired Attorney Abel H. Fernandez

I had the privilege of working with Abel Fernandez on my workers’ compensation case, and I can confidently say he’s one of the best attorneys you can find. Abel was always available, responsive, and patient—he truly takes the time to explain every detail so you understand what’s happening every step of the way to win your case.

Hired Attorney Abel H. Fernandez

Attorney Abel Fernandez was always available to answer my questions and held with my wokers compensation case. He never gave up on my case and fought the other side hard. I felt he explained things to me like a normal person not like an attorney. I recommend him and Diefer.

I would give 100 stars if I could. Hired them for a sexual harassment lawsuit and they were so understanding and professional and fought very hard for me in court. My attorneys always answered my questions and believed in me. I finally won in court a settlement I could never have dreamed off and my dignity that someone believed in me. hope to never need them again but I would recommend.

I called around and spoke to many law firms. Attorney Dieguez called me himself and really listened to me and took my case. He explained the lawsuit process and answers my questions until we settled the case. The result was more than I could have expected when k called.

Hired Attorney Marcelo A. Dieguez

Mr. Dieguez represented me in a really contested employment case. He always believed in me and my case and worked very hard to get me a great result. After fighting the case for over a year, I received a great result. Super happy with his services. I hope I never need another lawyer, but if I ever do I would not hesitate to use Mr. Dieguez again.

Lawyers.com Client Reviews

Martindale-Hubbell® Client Review Ratings™ display reviews submitted by individuals who have either hired or consulted the lawyers or law firms.

The Client Review Rating score is determined through the aggregation of validated responses. People who submit reviews are either individuals who consulted with the lawyer/law firm or who hired the lawyer/law firm and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be anyone who consults or hires a lawyer including in-house counsel, corporate executives, small business owners, and private individuals.

Martindale-Hubbell validates that a reviewer is a person with a valid email address. As part of the review process, respondents must affirm that they have had an initial consultation, are currently a client or have been a client of the lawyer or law firm identified, although Martindale-Hubbell cannot confirm the lawyer/client relationship as it is often confidential. The content of the responses is entirely from reviewers.

Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review. For more information on Martindale-Hubbell Client Review Ratings, please visit our Client Review Page

Martindale Peer Reviews

Martindale-Hubbell® Peer Review Ratings™ are the gold standard in attorney ratings, and have been for more than a century. These ratings indicate attorneys who are widely respected by their peers for their ethical standards and legal expertise in a specific area of practice.

The Martindale-Hubbell Peer Review Ratings process is the gold standard due to its objectivity and comprehensiveness. Lawyers solicited for peer reviews include both those selected by the attorney being reviewed and lawyers independently selected by Martindale-Hubbell. All reviewers are verified as attorneys through Martindale-Hubbell’s extensive attorney database. Only attorneys practicing at least three years and receiving a sufficient number of reviews from non-affiliated attorneys are eligible to receive a Rating.

What are the different Martindale-Hubbell Peer Review Ratings?*

• AV Preeminent®: The highest peer rating standard. This rating signifies that a large number of the lawyer’s peers rank him or her at the highest level of professional excellence for their legal knowledge, communication skills and ethical standards.

• Distinguished: An excellent rating for a lawyer with some experience. This rating indicates the attorney is widely respected by their peers for high professional achievement and ethical standards.

• Notable: This rating indicates that the lawyer has been recognized by a large number of their peers for strong ethical standards.

Lawyers who have received peer reviews after 2009 will display more detailed information, including practice areas, summary ratings, detailed numeric ratings and written feedback (if available). Details for individual reviews received before 2009 are not displayed.

Attorneys that receive reviews from their peers, but not a sufficient number to establish a Martindale-Hubbell Peer Review Rating, will have those reviews display on our websites.

For more information on Martindale-Hubbell Peer Review Ratings™, please visit our Ratings Page on Martindale.com and our Frequently Asked Questions

Avvo Client Reviews

Ratings and reviews are feedback from people who have either consulted an attorney about an issue (but may not have hired the attorney) or people who hired an attorney as a current or former client and provided their feedback to our sister site, Avvo.com.
