I was privileged to work with Bob for about 20 years, while he was at P&G and in his role as a consultant/medical writer after he retired. He was a gifted scientist and educator, and more importantly a kind and caring man. He made countless contributions to P&G scientific publications and dentalcare.com CE courses. I learned so much working with him and appreciated his patience and encouraging attitude. Of all his accomplishments, his family was clearly his pride and joy and his reason for being. Bob left this world a better place. He will be greatly missed.
