Kathy Siklos was born in Budapest, Hungary and completed her studies at the Budapest Art School.
She left the country during the 1956 Revolution and immigrated to Canada. Her professional career started in Montreal as a lithographer while keeping up her art studies and taking part in exhibitions.
In 1973 she moved to Toronto with her family. After her children left for universities she was able to devote more time for her paintings, exhibiting in various government agencies, Etobikoke city hall and education centre, several coffee houses and galleries.
She lives in Toronto and loves to spend time at her Muskoka cottage where she finds inspiration in the vivid Canadian colours.
