Professional background

I am a lawyer in the Public and Regulatory Law Department at Fieldfisher’s Madrid office. Prior to joining the firm, I worked at a well-known Spanish law firm specialising in the same practice area.

I have extensive experience advising national and international companies on administrative and contentious-administrative proceedings before all types of public sector entities. My practice focuses particularly on public procurement, urban planning, environmental law, and all regulated sectors, with a special emphasis on energy and natural resources.

I hold an Executive Programme in Public Procurement from the University of Deusto, as well as a Law Degree and a Master’s in Access to the Legal Profession from the University of Zaragoza. I also prepared for the entrance examinations to join the Legal Corps of the Spanish Ministry of Defence.
