landlord & tenant rights

John was exactly who my partner and I needed to help with a tenant problem. We didn't have a clue as to what our rights were as landlords. He went to court with us and guided us through the legal process professionally. John was very efficient and prompt in getting our problems solved. We have reco...mmended him to others.

Excellent legal services

I highly recommend John Brennock for any legal needs. He has assisted in a number of legal services including property sales, real estate transactions, and refinances through a power of attorney. His legal knowledge and advice is sound and in depth. His services very are timely and accurate.

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.
