Personal injury lawyer | Aug 25

Relationship: Fellow lawyer in community

"I have known Mark Henness for more than thirty years, both as a colleague and as a friend. My practice is primarily transactional and estate-focused, so personal injury matters that come to my office get referred out — and his firm is at the top of my list. He is thorough, well-prepared, and has real depth of knowledge in this area of law. Over the years I have referred not only clients but friends and members of my own family to him, and I have never once hesitated in doing so. Mark is a man of character with a moral compass that is a credit to our profession, and he carries that same integrity into the way he advocates for his clients. I recommend him without reservation and hold him in the highest regard."

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.
