Raised and educated in France until 1967, Gregory went on to follow his passion for art and design in his beloved Lebanon's Académie Libanaise des Beaux-Arts from which he received a degree in Interior Architecture. Since then, his success and growth have been ceaseless, as well as the praise for his work on an international level, including being listed by Architectural Digest as one of the world's top interior designers on more than one occasion.

In 1987, Gregory made one of his most defining moves in opening Gatserelia Design International in Toronto, Canada with his brother Alexander. However, with the end to the awful civil conflict in Lebanon, Gatserelia saw a remarkable opportunity to contribute to that Nation's reconstruction while being a part of a remarkably vital creative scene there and, in 1996, he moved the company's central office to the jewel-city of Beirut. From there, Gregory Gatserelia has quickly moved across the globe.
