Ray was an active member of the Minnesota Nursery and Landscape Association, where he served as President from 1979–1980. Through his dedication to horticulture and landscaping, he strove to make the world around him a more beautiful, enjoyable place to live. Bob loved what he did as well, and was dedicated to helping the business continue to grow throughout the years.
In 1957, Dundee welcomed a new business partner in Jerry Theis. Jerry had worked for Dundee for several years before becoming an official third partner. As he liked to say, he “grew” with the business. In 1978, Bob retired from the business, and Ray did the same the following year, leaving the Theis family—Jerry and his wife, Elaine—as the sole owners.
