Hello and welcome to this Auditory Processing Service (APS) website. Based on more than 55 years of clinical, research and teaching experience, I come to my work with a great deal of background and successful outcomes.

This website will tell you something about me, my thoughts on matters dealing with Auditory Processing Disorders (APD), as well as tests, therapy materials & computer programs that I have developed (with others). It also contains the type of lectures and workshops that I conduct.

Click on Services if you would like to have information about my lectures/workshops or about my tests, therapy materials or computer programs (supplier information is included).

Because of the shortage of APD services in the Kansas City area, I opened my own practice for both evaluation and therapy in 2004. For more information, please see Services.
