His modern abstract work began in the early 70s with painted constructions, and prints of space and nature themes. In the mid-80s he began constructing dimensional paintings, some over seven feet square. In 1997, he moved to Sun City, and began the work he called "Random Modalities" where he incorporated the frame as part of the art(a technique he has patent pending).

During World War II, Boris served in the Army-Air Force, painting huge murals depicting inspirational military themes. After the first one he finished, the commanding officers were impressed and asked him to do another, five by 17 feet at the hospital at Ft. Dix, New Jersey. He would later boast he asked for (and received) four men and two months to do the job. After the war, Boris began a family with his wife, Faye, and started in commercial art with J Walter Thompson. It wasn’t long before he struck out on his own as a portrait artist, working in pastel, charcoal and oil. Summers were spent in the Borscht Belt of the Catskill Mountains, and during Winters, Boris worked aboard cruise ships, painting portraits and giving lessons.

The work of Chezar has been exhibited in the Brooklyn Museum sponsored National Print Exhibition and other important group shows at the National Gallery,Washington, and the St.Louis Art Museum to name a few."
