Theresia Ghostine graduated in 2015 from the Lebanese University of Fine Arts. Choosing a path of continued education, she completed project management, contract administration, and execution management courses, along with green building design. Theresia then worked with G.R.O.W. architects, where she began her professional practice. As an associate, she rose to handle national projects.
Alongside G.R.O.W., Theresia took charge of architectural projects from A to Z under public or private orders, whether new construction or rehabilitation. In 2020, the idea of T20 Studio came to light, with an interesting background and knowledge. More clients entrusted her with their projects, from the small scale of creating a pool house to a touristic resort design. With T20 Studio, Theresia developed a personal approach to the profession characterized by meticulous technicality and disciplines with the main and only objective: creating the urban world of tomorrow.
