Graduating from California State University, Sacramento, Pruner completed his masters in oil painting.

A modern poetic realist, Pruner is a master of form and color. Imparting poetic imagery in his subject matter. Pruner's uncanny ability to juxtapose the images and at the same time draw an association between animal and plant life with a special color and posture of presentation is masterful. His total love for the mediums in painting has led him to a provocative and innovative technique that reveals itself in a bold and sensitive manner. The stimulating inner glow of his paintings, whether it be in oil, watercolor or oil pastel is an exclusive Pruner characteristic.

Pruner's shows have traveled both nationwide and abroad with many works settling into noteworthy permanent collections such as; The Kansas City University Museum, E.B. Crocker Museum, Monterey Peninsula Museum, Bell Telephone in Chicago, and M.T.S., Inc. (Tower Records) His reputation has broadened with exposure through traveling shows in Germany, Paris and Sweden.
