Client Testimonials

  • Leo & Oginni Trial Lawyers were absolutely awesome taking on my case. John Leo was my direct contact person and he was nothing short of amazing. Anything I didn’t understand, he was able to break it down to where i would understand it. Any information that was received from the other insurance company, he was sure to keep me informed. John kept me informed on everything. The process was long at all either. He played no games with the other insurance company and I appreciated his concern for me and my health, and his knowledge and professionalism concerning my case. Absolutely awesome and I would recommend Leo & Oginni Trial Lawyers to anyone! Thanks again!

    Danielle Rudley

  • Recently got rear-ended with not very good insurance. Out of all the firms I came in contact with, Leo & Oginni Trials were the only ones able to take care of me. They were very understanding and flexible and did not charge for a consultation. They were able to answer all my questions. Was not treated like an average client, more so like family! If you ever need the right attorney this is the best law firm you could come too. Most attorneys just want your money, these ones right here just want to help. These 2 men are so genuine.

  • This was my first time ever experiencing hiring an attorney in any form of situation.

    1. This firm made me feel very important in my decision making while giving me advice that would put me in the best possible position.

    2. One thing I also love about them is there availability.

    3. The person that was assigned to my particular issue never sold a dream to me but gave me honest facts that would lead me to the best opportunity in the situation I was placed in.

    4. This firm is very detailed. They walked me through everything and explained every possible outcome through each decision they suggested.

    I highly recommend hiring them. Their prices were more than reasonable and their professionalism was unmatched.

  • John helped me out with a last-minute case. The price was affordable compared to other firms, I called about 4-5. He communicated via text and email every day and was genuinely concerned about my well-being. My case was dismissed, I am satisfied and I would highly recommend them to anyone needing a great lawyer.
