 I appreciate you having me on the show. It's a pleasure. My full name is Dr. Alastina Malakova, but you're definitely right. Dr. Tina is short and sweet, so it's easier to say. So as a dentist, it's kind of a nice coincidence that the invention idea is a toothbrush related to the dental field. And it was born out of the idea of patients' interest to have a toothbrush that lasted a very long time.
