Lake Castle Slidell Private School in Slidell, LA, began in 1987 with a motto that still forms the backbone of our educational philosophy today: "Excellence in Education."To fully understand what Lake Castle is all about, it is recommended that interested parents attend one of the orientation meetings scheduled during the year. We firmly believe that a solid education combined with old-fashioned values will enable our youth to successfully face life's challenges. At Lake Castle, "Excellence in Education" is not only our motto, but it is our modus operandi, and it is a tradition we are proud to continue.
