Reza Izadi is anything but a normal dentist. His app startup emerged from his private dental practice, where he saw a problem with traditional interaction between dentists and their patients. With seed money from savings and colleagues, he aims to disrupt the way patients find their dentists. His app, Denteractive, is like Yelp -- for toothaches.

Why did you chose to create a startup in your industry?

I have been fortunate to be part of a very rewarding profession for the past 20-plus years. Dentistry is a mix of art, science, direct patient care, technology and business. I absolutely love my profession, but I also have seen the challenges that patients and dentists face every day. We made Denteractive.com as a bridge to bring dental consumers and dentists closer through technology. Our goal is to enhance patient relationship management for dentists while providing consumers easier and more comprehensive access to dental care.
