In 2010, this family-owned business invested in a larger building at 195 Commercial Square, located in the heart of the east side of Slidell, Louisiana. The owners, Neivair Castilho and his wife, Cristina Dellarrosa, came up with GNL as a symbolic way to show their love to their children: Gustavo, Natalia, e Leticia. Since then, we have built loyal and long-term customer and partner relationships and are very proud to have the best reputation in our area, accumulating 133 Google Reviews that only grow daily.
