Patti has also written several books for parents (Childhood Speech, Language & Listening Problems: What Every Parent Should Know: Wily & Sons) as well as speech/audiological professionals (A Metacognitive Approach to Treating Auditory Processing Problems, Pro-Edinc.com ) and classroom teachers (It's Time to Listen). She has been awarded the honor of "Fellow" by the California Speech-Language Hearing Association for outstanding clinical work.
