He worked in many areas of pharmacy including hospital pharmacy, outpatient pharmacy and clinic trials in medical oncology. John enjoyed playing racquetball and spending time with his dear family. He was devoted to his Greek Orthodox faith and its culture. He was a man of great integrity who had a kind and compassionate heart.
