In the early 90s, working as a trainee in an office in San Sebastián, one of my University friends (Luis Unceta) convinced me to join what was going to be his greatest ever project: BSK. Fortunately, I was lucky enough to accept this invitation as that particular dream has come true over time.

I am particularly nostalgic looking back at the first (and now distant) years at BSK: only three lawyers and a secretary, with few resources but bags of enthusiasm to make a go of it. And above all else, always focussing on the client, all their needs and attempting to always give them the most streamlined, highest quality response possible.

Over the more than twenty years that I have been working at BSK, I have been able to grow personally and professionally at the same pace as both the Firm and many of its clients. I have also been able to work with and trained many of the people who now lead new practice areas at BSK. However, if I am proud of one thing, it is being able to see that the same principles used to set up the company (work, quality, training and review) are exactly the same as those that nowadays continue to inspire more than fifty professionals currently working at BSK.
