Our Values


Our overriding aim is excellence as a law firm.

Therefore, our team is made up of lawyers that have graduated from the top universities (namely Harvard, Georgetown, ICADE, Universidad Autónoma of Madrid and LUISS Guido Carli of Rome) and with extensive experience built working at leading international firms.


We build long-lasting relationships. We earn the trust of our clients by rigorously applying the maxims of our office: loyalty, confidentiality and a sincere respect for privacy.

We are committed to providing an honest, close and continuous communication that allows our clients to make well-informed and efficient decisions.


In Goy Gentile we firmly believe that the best possible result is a completely satisfied client. We deliver excellent client service in a cost-effective manner.

Our goal is to achieve tangible results through agile and efficient processes. We strive to proactively anticipate the needs of our clients and exceed their expectations.

Global Vision

The international professional and personal trajectory of our lawyers, who are all bilingual, has made our international dimension an inherent part of our practice.

We understand the different cultures of the jurisdictions in which we operate which enables us to approach each case with a global vision.

Goy Gentile was founded as an international law firm based on excellence and results but without ever compromising our absolute loyalty to our clients through close and trusting relationships often missed in large firms.


Our law firm, located in Madrid, was founded by Lucía Goy Mastromiechele (LL.M., Harvard Law School). Before, she worked for leading international law firms, such as Uría Menéndez, Skadden, Arps, Slate, Meagher & Flom (one of the most renowned firms in New York) and Davis Polk & Wardwell (also from New York). Her international experience and her knowledge of the different business’ cultures of the jurisdictions in which the firm operates provide Goy Gentile with a unique approach and a distinct added value for our clients.

Goy Gentile was born with a strong international character. We aim to become, through our technical and operational excellence, the reference law firm for connecting the jurisdictions in which we operate: United States, United Kingdom, Argentina and Spain.

The sum of the international experience of our team makes us a firm with a solid background in the most competitive legal markets in the world: the US and UK markets.

In Goy Gentile we have faced the most complex transactions and have learned the importance of innovation to obtain the best results.

Whether it is a divorce, inheritance or a real estate transaction, Goy Gentile does not only seek to achieve the best possible results for our client, but also offers solutions that havethe most advantageoustax terms.

The Law Firm’s unique approach, beyond quality and loyalty, is the tax optimization of all the matters in which it participates.

Furthermore, at Goy Gentile we have native Spanish, English, Italian, French and Russian speaking lawyers, which allows us to communicate closely with our clients and any third parties involved.
