[1] A master of the alla prima approach made famous by John Singer Sargent, he achieved many singular accomplishments, among them, painting nationally known subjects in the public sector.

Del Priore lived in Fork Shoals, in upstate South Carolina,[2] however, he garnered international acclaim in his 40+ year career by doing over 850 oil portraits that included Members of Congress, Supreme Court Justices, Governors, clergy, educators, physicians, cultural, corporate, and community leaders.

Del Priore's most notable portraits include President Ronald Reagan, Microsoft CEO Bill Gates and former Speaker of the House, Representative John Boehner.

In the lobby between the two chambers are Del Priore paintings of U. S. Representative, William Jennings Bryan Dorn, and famed Midlands educator Wil Lou Gray.

[9] Cassone, who had studied at the Art Institute of Chicago and the Accademia di Belle Arti in Florence, Italy, saw Del Priore's raw talent but noted his lack of experience and told him to, "Go home and draw a thousand heads, then I'll teach you what you need to know."

Cassone never expected to see him again, but made good on his promise, introducing Del Priore to master techniques of portrait painting in oil and pastel.

Goodbred taught him master skills including palette organization, anatomy basics and manipulation of brushes by painting from live models and doing still life studies.
