Avoid James Diefenbach and Diefenbach Law Group

Between 2022 and 2026, my experience with James Diefenbach of Diefenbach Law Group was horrible, including 1) He does not care about the outcome of legal cases, but instead only cares about his compensation, 2) He did not do most (80%) of the things he said he would do, 3) He mishandled an offer in c...ompromise for a legal case because he did not pay attention, 4) He showed up to trial each day without brushing his teeth making it very difficult to interact with him, 5) He failed to propound any discovery for a legal case, 6) He allowed a legal case to be dismissed with sanctions because he did not pay attention, and 7) He believes he is entitled to his misconduct because he is an attorney. James Diefenbach of Diefenbach Law Group is a liability and has caused me more damage than any person. Avoid James Diefenbach and Diefenbach Law Group.

Respectful and Generous

James is an extremely professional Attorney. He successfully obtained a settlement for me and treated me with respect and a great deal of generosity. I would definitely hire him again should the need arise in the future and I highly recommend his services.

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
