Conrad has been involved with Richters since its inception in 1967 when he was still a child, helping in the greenhouses and in the fields after school and on weekends. His interest in herbs took flight when he helped his father prepare the first Richters herb catalogue in 1970. He has worked on every Richters catalogue since. He has a primary responsibility for research and development and through his efforts many herbs new to gardeners in North America have been introduced over the years. More recently, he and his wife have been studying and growing notable African herbs in Ghana, West Africa, for export.
