It is with great sadness that acknowledge the passing of Dr. David Shuttleworth on March 19th, 2021. Many of you will remember him as a doctor with whom I shared call. In 1981, he and Dr. Donald Frank (my pediatrician) welcomed me into the private practice of pediatrics. Dr. Shuttleworth, especially, become more than an associate — he was a mentor, a confidant and most importantly a dear friend. He will be sorely missed.
