About Thomas

Learn Thomas’s areas of practice.

Practice areas
  1. Government
    In addition to his litigation practice, Tom represents a number of medical marijuana cultivator, processor, and dispensary applicants He also advises ancillary stakeholders on cannabis law.

  2. Litigation
    Attorney Haren also litigates civil matters on behalf of business owners and individuals. He is also an enthusiastic supporter of the First Amendment, and defends individuals sued for defamation based on constitutionally-protected speech.

  3. Criminal defense
    Being charged with a crime can be devastating not only to the accused, but to the accused's family. The stakes can be high and the penalties harsh. Tom Haren believes that each client's case is unique and deserves individual attention.

I help businesses and individuals when they find themselves involved in high-stakes litigation, whether they are sued in a civil action or need to defend against government investigations and prosecutions. 

I also advise a number of companies regarding Ohio's medical marijuana law, including license applicants and ancillary industry stakeholders.

Helped me keep my job!
My job requires that I maintain a good driving record in order to remain employed. Last year I put myself in a position where my employment was at jeporady. With Tom's representation the court reduced the charges and I was able to keep my job. I sincerely appreciated how quickly he worked to resolve this issue so that I would not lose any time from work as well as the favorable result.

Excellent representation.
Thomas showed utmost concern for the case and provided very in depth service allowing for a highly favorable outcome. At all times he was reachable and willing to explain every step of the case so I was fully informed. Mr. Haren, though it might be a small ordeal, but was always on time for any and all meetings and was always prepared. The service was unmatchable with him going well above and beyond and I highly recommend Atty. Haren for all needed legal services!!

Thomas Haren was/is the perfect legal representative for me and my family - Totally Trustworthy!
Although Tom is young, his knowledge, skills and ability to negotiate the court system was very impressive. He was inquisitive and thoughtful in our consultations. Bottom line, he got my sentence reduced to a minor charge which is why I hired him, and did so in a friendly, efficient and enthusiastic way. I'd gladly recommend him.
