Jeff Hertzberg, M.D. grew up eating great bread and pizza in New York City. He continues to teach the importance of moderation and variety in a healthy diet, and works as a medical director and consultant focusing on health-improvement programs. During his medical residency, he started a years-long quest to figure out how to make dough that was convenient enough to use every day. He turned an obsession with bread and pizza into a second career as a cookbook author.
