Hired Attorney Mark R. Osherow

We worked with Mark on a contract issues with a home builder and their in house lender. The mortgage company was blatantly violating the law and attempting to keep a large portion of our money that wasn't theirs. We were worried such a complex antitrust matter would take years to resolve... However, Mark met with us and provided a timely and in-dept analysis which clearly determined the lender was violating the law, allowing us the terminate the agreement immediately. The lender conceded and agreed to refund us. Having Mark saved us tens of thousands in up-front costs, not to mention over 100k in a predatory interest rate. Mark and his staff are incredibly responsive, knowledgeable, and honest. I will be referring him to anyone who needs a contracts, litigation, or business law attorney!

 
Bankruptcy

Hired Attorney Mark R. Osherow

Members of my family were defrauded out of a large sum of money by an exceptionally charismatic, ruthless individual who ultimately presented them with a worthless six-figure check. She later filed for bankruptcy without listing them as creditors. I am a Florida lawyer and family members turned to me for help in finding the right lawyer to represent them. Mark Osherow was the right lawyer. I contacted him after reading an article on civil theft that he had written for the Florida Bar Journal. Mark took their case, which I continued to follow. He prepared powerful pleadings comprehensively documenting the defendant's fraud. The matter had also attracted the attention of law enforcement. Thanks to Mark's skill, the matter was settled with the approval of the bankruptcy court. The defendant repaid the full amount she had taken with interest. Needless to say, we will always be grateful to Mark and his Firm for their outstanding representation.

Hired Attorney Mark R. Osherow

My firm is a small business provider of IT services which had a service agreement with a large enterprise client. The client, in our opinion, breached the agreement and refused to pay the balance of the term. I hired a firm that I believed to be experienced in complex cases/contract law to file the complaint. After 9 months and spending tens of thousands of dollars with no satisfactory results, I terminated the original counsel. I posted my case with the Florida Bar Referral Service to find a trusted attorney. I connected with Mark Osherow of Osherow, PLLC. Mr. Osherow is a Florida Bar Board Certified Business Litigation Lawyer since 2006. Mr. Osherow took the time to fully understand the nuances and technicalities of our services and claims. The defendant originally made low offers to settle. In 5 months, Mr. Osherow and his team masterfully and successfully settled my case. I wholeheartedly recommend Osherow PLLC.

Hired Attorney Mark R. Osherow

If you want the best lawyer in town, Mr. Osherow is the one. If you want to win your case with the least expense he is the one. I have had dozens of lawyers in the past for various reasons and among all of them I found Mr. Osherow was the most knowledgeable with a sharp legal mind and a drive and dedication. He understood my complex case in one narrative and and paid attention to details and came up with a winning strategy which I readily agreed and approved. It was a team effort between me and my lawyer which led to a withdrawal of the case by the plaintiff with out any liability on my part It was a multi million dollar liability lawsuit against me and my family and I walked out of the lawsuit victorious. Was it not Mr. Osherow to defend me, I would still be fighting my case and spending hundreds of thousands of dollars .I strongly recommend Mr Osherow for you.

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.
