[Ticket][PMT] BEI Deployment

**Non-Profit Description**
Brain Exercise Initiative (BEI) is a nonprofit focused on preventing memory loss through brain exercise. Its founder is UCLA student Esin Gumustekin, who draws inspiration from the research work done by Dr. Ryuta Kawashima. Gumestekin creates daily packets which include simple math, writing and "read-alouds" that are completed by each individual with the guidance of university students. Several retirement homes have integrated her program into their center and chapters are currently being founded at different universities.
