I am more than happy to recommend John Cunill and his team for your legal representation. As an out-of-state client, I desperately needed an attorney due to a vendor issue in Florida. After randomly calling around and speaking with some top-notch attorneys, Mr. Cunill came highly recommended—and for good reason. John’s professionalism, efficiency in handling the case and negotiations, and his willingness to minimize clock time all contributed to achieving the best possible outcome. He was respectful, friendly, approachable, and everything you could ask for in a personal attorney. John clearly has deep expertise in business law. In our conversations, he drew on personal experience dealing with bad faith players, which gave me great confidence in his strategy and advice. Everything about my experience with John Cunill was top-notch. If I have the opportunity to do more business in Florida, I will do so knowing I have John in my corner if I ever need legal representation.

John is a great real estate attorney. He’s diligent, thoughtful and creative. We had another attorney last year and switched to John for this last deal and couldn’t be happier with that decision......
