THE BEST!!

Very helpful and down to earth and intelligent and was on my side every step of the way! He gave me great advice too! God bless you!

Posted by anonymous | September 11, 2014

Great Lawyer!!

I hired Johnny to represent me on several Dallas County felonies. Given my criminal history and the nature of my cases, he was able to get me a reasonable deal with minimal expense and probation conditions!! I would highly recommend him for anyone in a similar situation!

Relationship: Fellow lawyer in community

"Johnny Lanzillo is a competitor in all senses of the word, and this characteristic defines his advocacy. When representing his clients, I have found him to be relentless - whether that is through traveling half the state away to take care of something that another attorney would've farmed out, or in putting in the time to prepare for trial. Strongly recommend him to anyone facing legal troubles."

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.
