Keith Klein's work is part of the collection(s) of the Princess of Saudi Arabia, Cincinnati Bell, Convergys, Cincinnati Financial, and many prestigious private collections across the United States. Klein studied with Anneliese Wahrenburg in her atelier for ten years and trained in the Hague School manner of painting in her atelier for ten years. Ms. Wahrenburg emigrated from Germany after being imprisoned in a Nazi concentration camp for sheltering and helping Jewish people during the war. 

Keith is amazingly diverse, with styles that range from classical realism, impressionism, pointillism to paintings done en Plein-air – always painted with his recognizable "voice" even in these divergent styles. He often puts surprises and symbols in his work that are delightful to find.

Keith's studio in Florence, Kentucky, was built in 1903 and was once the First Florence Deposit Bank. Keith teaches classes in oil painting, acrylics, pastels, and watercolor five days a week in his studio. Many of his students are accepted into the prestigious Governor's School for the Arts and awarded full scholarships for college. He also has a particular affinity and gift for teaching special needs children and adults.
