After his certification, Skinner moved to Coral Gables, Fla., where he established a solo private practice. In addition, he worked at Jackson Memorial Hospital in Miami and was a professor at the University of Miami School of Medicine. Skinner retired in 1988. Skinner was a fellow of the American Academy of Dermatologists and the Investigative Dermatological Society. He also was a member of the Miami Dermatological Society and the Southeastern Dermatological Society.
Skinner also is a world-renowned authority on wines and fine dining.
He recently completed a second book on dining in Paris bistros. Skinner is one of a small number of grand-scale wine collectors. But while many collectors would rarely consider drinking one of their rarities, Skinner opens his rare old wines periodically and serves them to other connoisseurs. In 1992, he estimated that his air-conditioned wine cellar contained some 3,000 bottles, of which about 300 were 1961 Bordeaux, considered by many wine professionals to be the finest Bordeaux vintage of the 20th century. Skinner's collection of 1961 Bordeaux began with a visit to Bordeaux in 1963.
