Maris has a phenomenal and unique manner of reflecting the color and light in nature. His formal drawing courses were at the Art Institue of Latvia. Maris belonged to Zemudene, a group of young artists in the 1970s and 1980s who were trained on a regular basis by well-known Latvian artist Biruta Delle. Delle and Zemudene were written about in detail in “Art of the Baltics: The Struggle for Freedom of Artistic Expression Under the Soviets, 1945-1991” by Alla Rosenfeld, Norton Townshend Dodge.
His work has been exhibited in Europe in such places as the Museum of Biology and Natural Sciences, The Theater Museum, the O. Vacietis Poet's Museum, the Open Air Exhibitions at Arkadia Park, and the Cesis History Museum, Bikur Holim Hospital, Ark Clinic, and City Hotel Bruninieks.
When Maris moved to the United States in 2001 his art grew in freedom of expression which expanded the foundation he gained in his Zemudene years.
His work has been exhibited in the United States at the Continental and Phoenix Buildings, Antonio Raimo Gallery, Upstairs Gallery and Elder Street Gallery. He was elected into the Salmagundi Club, Fifth Avenue, New York as an artist member. In 2012 his art was shown there at a solo exhibition.
