Born in Seville, Patrick Gilles grew up in the southeast of France in Marseille and then Montpellier. He came to Paris for his higher education and was admitted to Camondo, one of the leading interior design schools in France. After graduating, he joined Christian Liaigre’s interior design agency. He worked there for 9 years where he designed furniture, alongside Christian Liaigre. This is also where and when he met Dorothée. He later created his own interior design agency, PG studio. Having to deal with rapid success and increasing demands from his clients, Patrick and Dorothée had no other choice but to start their own agency in 2004.
