Alvarez & Diaz-Silveira LLP (ADS) is a Miami-based corporate boutique law firm focusing on international and domestic M&A, finance, real estate, immigration and private wealth services for leading companies, family offices and high net worth individuals. Created by experienced attorneys from premiere global firms, ADS combines sophisticated counsel with a level of execution, personal attention and value that is rare among practices today.


We are seasoned practitioners in our fields of expertise with extensive transactional experience.

The firm was founded in July 2012 by Pedro A. Alvarez, Alejandro M. Arrieta and Albert Diaz-Silveira, experienced corporate and business lawyers who have practiced together for many years, at a major global firm. In establishing the firm, the founders sought to create a corporate and business law firm focused on serving private clients and middle market participants in domestic and cross-border matters as an alternative to the traditional full-service leveraged firm.

The firm’s senior lawyers are all experienced transactional practitioners, and a number of them are recognized by Chambers & Partners, as well as other organizations, for their professional accomplishments. The professional recognition received by members of our team are described in their biographies.

Our firm is minority-owned and is a member of the National Association of Minority and Women Owned Law Firms. Our lawyers belong to, among other groups, The Florida Bar, the District of Columbia Bar, the New York State Bar, the American Bar Association, the International Bar Association, the Hispanic National Bar Association, the Dade County Bar Association, and the Cuban-American Bar Association. Many of our lawyers also hold leadership positions in community organizations.
