Many know HOWARD DEAN as the liberal politician with the "I Have a Scream" speech during the 2004 election, but what many don't know is that he's a physician as well. Combining his doctor-of-medicine background and political career, the former Vermont governor and chairman of the Democratic National Committee visits Atlanta to discuss his new book, Howard Dean's Prescription for Real Healthcare Reform. The novel maps President Barack Obama's health care plan, Dean's beliefs on what needs to be done to successfully reform the nation's health system, other nation's health care solutions, and how improving health care can be beneficial for American companies. A book signing will follow. Free. 3 p.m. Manuel's Tavern, 602 N. Highland Ave. 404-525-3447. manuelstavern.com. Read a review of Howard Dean's Prescription for Real Healthcare Reform.
