Our Firm

We Exist for Your Success.


Mercado & Rengel is law firm founded over 20 years ago, dedicated to providing the highest quality legal advice and service to our clients in an efficient and effective manner. Our mission is to protect your legal interests in both, domestic and international settings, with quality, efficiency, honesty, and confidentiality.


With offices in Boston, Madrid, and Miami; and attorneys licensed in various jurisdictions, we represent our clients not just in their language, but also with the understanding that only comes from being knowledgeable about the different legal systems in which we practice. We strive to provide each client with professional, timely, and personalized legal service to obtain the best results.


Our clients are the reason for the very existence of Mercado & Rengel, and they are also our partners. At the moment we start representation, our interests become aligned and we strive to achieve success for our clients, because we consider our clients success our own. A true partnership is a two-way street – ideas and information flow openly and regularly, based on a foundation of mutual trust and respect for one another — and our clients embrace this philosophy.

Our clients include corporations, entertainers, executives, elite athletes, business owners, investors, and individuals from around the world. We utilize our interpersonal skills and the technology available to facilitate constant communication with our clients regardless of location.


Our firm is committed to the constant search for perfection through personal and professional development of each member of our team. Members of our team participate as university faculty, lecturers, continuing legal education instructors and as mentors for young attorneys and others. Our work contributes to the strengthening of the legal field, making a reality of the values of justice, liberty, and equality.
