    Derek Byrne and Andrew Mallory are the best attorneys in all of the Tampa Bay Area. They are the only attorneys I recommend to my clients, owing to the fact that have true integrity and kindness. This has proven to be almost impossible to find within the family or accident law fields. I do not say this lightly, speaking as someone who has been on the sharp end of family law attorney fee gouging to the tune of six figures. They are both fair, human, wonderful, empathetic and real. They are not trying to protract and ignite already tenuous and painful situations for their financial gain, which sets them apart from most. Personally it is the only law firm for me. I simply would not trust anyone else.

    Awesome experience!

    I hired Derek Byrne for my family lawyer and it was taken care of quickly and easy for both parties involved. His expertise is his field are great.

    I recently got a DUI and hired Andrew Mallory. He made me feel comfortable in an uncomfortable situation and he’s knows his job very well. I’m 100% glad I hired him.

    Both experiences were awesome and I highly recommend.

    I had my first experience using a law firm with Byrne Mallory. They immediately put me at ease and gave me a true sense of confidence throughout the process. The entire team was professional, caring and extremely knowledgeable. I would use them again for any and all of my legal needs. Thank you both!
