“Sleep-related Crimes”

After helping to establish the Center for Sleep Disorders at Penn in Philadelphia, my family and I relocated to a private practice in Pittsburgh. The enjoyment and gratification that accrues from treating patients with sleep disorders and respiratory conditions have remained my primary motivation. In particular, I have been in the field of Sleep Medicine longer than most, with an intensive academic and research background that continues to serve me well today. I have been fortunate to present at many national meetings, as well as a multitude of local and national radio and TV programs regarding sleep disorders. I also continue to conduct active research in the newest modalities available for the treatment of various sleep-related conditions.
