I was shocked and saddened to learn of Allen's sudden death. We were friends for many years and had offices across the hall from each other for many of those years. We were close professional colleagues and good social friends as well. Allen was a superb neonatologist and also had a great sense of humor.He will be sorely missed, My most sincere condolenses to Howie and Sheryl and other family members.--Herman A. Hein, M.D.
