A hospitalist at Stanford for almost 10 years, ZDoggMD (AKA Dr. Zubin Damania) is a physician, off-white rapper, and the founder of Turntable Health. He’s not a businessman. He’s a business, man. OK we stole that line from Jay-Z but you get the idea. Apart from writing, performing, and producing award-winning medical rap videos that educate and entertain, he’s a highly sought-after thought leader and healthcare speaker.
