The Associated Press calls him "Dr. Dad." Publisher's Weekly says one of his most recent books "places him firmly in the pantheon occupied by Spock, Brazelton, and Leach." Dr. Lawrence Kutner, who describes himself simply as "a guy who does a lot of different stuff," is a nationally known clinical psychologist who trained at the Mayo Clinic and teaches at Harvard Medical School, where he's co-director of the Harvard Medical School Center for Mental Health and Media.

From 1987 to 1994 he was the author of the award-winning weekly New York Times' "Parent & Child" column, which was also syndicated to several hundred other newspapers throughout the United States. That column won the 1990 American Psychological Association National Psychology Award as the best writing about psychology in the country. After spending eight years as the child behavior columnist for Parents magazine and the author of its "Ask The Expert" column, he left that position to become a columnist and contributing editor for three magazines published by Time Warner: Parenting, Family Life, and BabyTalk. He also writes for the online services Pampers.com and ParentTime.com.
