Therese Valdez a high school calculus teacher in NY with over 20 years of experience in education came up with the idea of a public restroom door lock, which holds your phone, to solve the problem of her students forgetting their cell phones in the public restroom. Therese with the help of her associate, John Lynn who has a mechanical and construction background, developed StallMATE™ the only smart phone holding device that also is a locking mechanism so you always have privacy and you never forget your phone! In order to exit the bathroom you have to remove your phone from the locking device and then open the door! It’s really that simple.
