John and his team, especially Leigh, were outstanding throughout my case. They were professional, effective, and consistently available whenever I needed them. Their communication was excellent—every call or text was either answered right away or returned the same day. I always felt informed and supported, and their dedication made a stressful situation much easier to navigate. HI highly recommend their services to anyone in need of strong, reliable representation.

Top level attorney. John was always seemed a step ahead of things and in the end my case went the way I needed it to. No matter where this roller coaster of a case went John was always able to respond effectively. I hope I never need Johns help again but if I ever do I could not think of a better attorney to stand by my side.

This man did what he tried to do! This man fought long and hard to get me probation. He clearly explained everything and went through numerous files/videos. This man is kind, patient, very intelligent and trustworthy. I am glad I got to know this man, I wish the circumstances were different of course but everyone in their office is kind. I hope to see him again under normal circumstances, no more court for me. THANK YOU JOHN AND GOD BLESS YOU!!

I did a LOT of research and calling before choosing John and I am so grateful for choosing him as my DWI attorney. From the first 30 seconds of talking to him, I knew he was the right choice to help me. I recommend him to everyone!!!!!

He was very caring and compassionate. Even though I had no choice at the time, I had a lot of guilt and bad feelings about bankruptcy and John took all of those away. He helped me through it mentally.

I didn't know it was possible to have so much trust and confidence in a lawyer. I also never really saw myself as having a lawyer that I could call my lawyer for help with all legal issues, and John has become just that. He has exceeded my expectations every step of the way and I would now consider him more of a friend than a lawyer. The level of personal attention he has given me has been astounding.

In general, I don't like lawyers. I didn't know that lawyers like John even existed until I worked with him. He is friendly, highly intelligent, super efficient, and quick to put out any fires you may have created before you met him. He's wonderful. I give him my highest recommendation!

I filed for Chapter 7 Bankruptcy and always felt confident working with John. He was easy to work with and never left me with any doubts. He made a stressful situation seem a lot less stressful. Highly recommended.

I sought John's expertise in dealing with a lawsuit for unpaid medical bills for my deceased spouse. Over the course of two years, I dealt with some uncaring and greedy individuals, but John was the complete opposite. He cared about my situation and showed compassion when no one else did. Not only did he help me settle my case, but he was so kind and considerate during a difficult time.

These FAQs include information about a lawyer's background, but do not evaluate their knowledge of the law, past performance on individual cases, personality, or communication skills.

It is solely the responsibility of lawyers and law firms to ensure that any information they provide complies with all applicable laws and rules of professional conduct.

You should be aware that the information we rely upon may not be comprehensive, or frequently updated.

Always research the lawyer further to get a better understanding of their license credentials, disciplinary status, background, and experience.

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.
