Founder (1944–2006)
André Goullet, a Fellow of the Association of Chartered Certified Accountants (FCCA), founded Fideso in 1980 with a clear vision: to provide Marbella's international community with expert tax and legal advisory grounded in trust, precision, and personalised service. With qualifications spanning both British and Spanish accounting frameworks, André built Fideso from a sole practice into one of the Costa del Sol's most respected advisory firms — serving clients across more than 52 nationalities. After his passing in 2006, the next generation took the reins: his son Douglas Goullet now leads the firm as CEO, together with partners Charo Barone Cobos and Jesús Núñez Caballero. André's vision, values, and commitment to personalised service continue to guide Fideso today.
