“I became a doctor to help people. Clinically, I am able to help a few people every day. However, I knew that through medical research I would be able to help hundreds of people every day. This is why I created AllergyStop® because I cannot think of a better way to help people than developing a device that will not only relieve the anxiety of millions but also save lives.”
