Outside of her professional life, Neena enjoys reading, writing, beach activities, hiking, and traveling with her family. She is also actively involved in charitable work through the Lions Club. She lives by the principle:

“Give, and it will be given to you. A good measure, pressed down, shaken together and running over, will be poured into your lap. For with the measure you use, it will be measured to you.” (Luke 6:38)

Indeed, she believes that it is in giving that we truly receive.
