Mohamad Obaidy
Director/ Owner All LocationsMr. Mohamad Obaidy, our fearless leader, is an inspiration to all of us to be the best caregivers we can be. His involvement in our day-to-day operations helps ensure success and smooth functionality.
Without his positive energy, kind heart, and love of early education, Nanda would not be the center we know and love today. Unlike most business owners, Mr. Mohamad makes it a point to show his employees that he genuinely cares by spending time in their classrooms. For this reason, among many others, students greet him by name and with a smile.
