Does chuck close do a style of art called pointillism?

Chuck Close is not primarily known for pointillism, although his work does incorporate a technique reminiscent of it. He is famous for his large-scale, photorealistic portraits created using a grid method and a unique approach to color application that resembles the appearance of pointillism. Close's process involves painting small, discrete marks of color that blend optically from a distance, but his style is distinct and not strictly categorized as pointillism.
