‘Mariana Fagioli, Santiago Castellan and Lucia Acosta are the ones who are attentive to my needs and immediately provide solutions.’
‘The team at Castellan is very complete and interdisciplinary. They have an excellent connection between professionals, and something that we especially value is that when they discuss issues between various parties, communication flows organically. You do not have to explain to each professional (again) the topic you are going to deal with.’
