Guillermo López-Chicheri

I joined Grant Thornton 9 years ago. Previously, I had provided my services in other professional firms, including KPMG, where I spent 9 years. 

Tax advisor and lawyer with extensive experience, solid economic and accounting training, and more than 20 years of experience in international and national tax advice to Spanish and international companies. Solid knowledge and specialization in all areas of the tax sector. Advice, planning and coordination of direct and indirect tax policies. My ultimate goal is to be a top-level professional in my area of expertise. 

I regularly advise my clients in various sectors of activity, including health, finance, energy and production. 

I coordinate the tax team in the Madrid office in M&A processes and in the performance of Due Diligence work. 

I regularly participate as a teacher and also as a speaker at universities and business schools, among others at the Fundación de Estudios Bursátiles de Valencia and at the IE Business School.  

I actively collaborate with non-profit entities such as CARITAS and the ALAPAR FOUNDATION. 

I have been recognized in 2025 by Best Lawyers as a lawyer in tax law.
