What People Say About Dr. Goldenthal's Presentations and Books


"Dr. Goldenthal was a fabulous speaker during the Parent Talk Lecture Series ( in May 2012. He spoke to an audience of over 100 parents of young children on the topic of Sibling Rivalry. Dr. Goldenthal was very easy to work with leading up to the lecture and was a pleasure to work with at the lecture itself. As a speaker, Dr. Goldenthal had a very calm manner, was easy to listen to, talked about what the audience was there to hear, and welcomed many questions. He was able to cover a lot of practical information for parents. We all wished we could have had more time to hear him talk. Dr. Goldenthal was also very willing to stay after the lecture for a book signing and to answer more personal questions. He was a pleasure to meet, connect with, and learn from."
