Hired Attorney

highly recommend Bill Trafidlo. I interviewed three lawyers and Bill was, by far, the best choice. He was instrumental in navigating me through the legal system to a successful outcome. Bill provided me with expert legal advice and guidance by offering various strategic options in a straightforward and easy to understand manner. He clearly knows the law, and I would have loved to see him in action at trial, however, he was able to negotiate a positive settlement for me. Glad we made the right choice for our attorney.

Working with this lawyer was a great experience. He helped me understand fully the violations and fees that could possibly be associated with my tickets, and worked out an agreeable plea with the state of NH.

Attorney Trafidlo was exceptional in his communication with me with from start to finish. He knows what he is doing and is well respected at the courthouse--from the troopers to the judges. Out of all the people waiting when I arrived, we went first. Attorney Trafidlo is professional, responsive, and thoughtful. I would highly recommend him as an excellent choice for handling your legal matters.

I'm so very happy that I hired Bill. He made a very frustrating and disappointing situation easier to deal with. He always kept me updated, explained everything thoroughly, and got my charge reduced. I would HIGHLY recommend hiring Mr. Trafidlo.

William was very hardworking and attentive and laid the perfect groundwork to get my case the decision I deserved. While working on my case, he always helped me understand the process and was always available to contact when I needed clarification or assistance. I can not stress that William should be your go-to if you are in a bad situation.

I appreciated him walking through everything with me in detail and making sure I understood the circumstances. I was stressed out to what happened as this was my first offense. He calmly shared with me the laws and possible outcomes. I followed his recommendations and we kept in touch. Being out of state, I was hoping I didnt have to travel to NH for trial due to costs. Fortunately he was able to have the trial changed to a telephonic hearing and we were able to settle this matter and decrease the charge. I am grateful for his representation. He is good at what he does!

Attorney Trafidlo was hired by recommendation from my lawyer from another state. He immediately reassured me that he could not only litigate the case to a satisfactory ending but made me feel he was doing what was in my best interest. He was very communicative and walked me through every step of the way.. A+++ Lawyer and I highly recommend him.

Attorney Trafidlo did an excellent job in getting my OUI reduced to a Driving to Endanger. He was very responsive and knowledgeable in this area of the law and his expertise worked very well in getting the charges reduced in my case.

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.

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
