Kleanthi was born in Piraeus on 22/12/1958. In her youth, she demonstrated a remarkable interest towards fine arts and especially painting. At the age of 17, she was awarded with the second prize at a painting contest which took place during the celebration for the Greek Navy, among contestants from all over Greece. Ever since, she meant to have an unbreakable bond with the good arts. Her first successful professional attempt was made at the section of handmade pottery, as she designed and manufactured special objects on her own. But she never stopped searching for further knowledge. So, she took lessons on drawing from the famous Greek sculptor M. Papadakis for several years, and she managed to become a more mature artist by obtaining knowledge which proved to be very useful in her future steps. Shortly after, she decided to dedicate herself to painting since she felt the most powerful attraction for that.
During her professional painting career, her work had a remarkably upcoming course, judging by the successful choices of the themes and techniques in her paintings as well as the constantly improving painting skills. Unfortunately, she passed away in November 2015.
Her paintings are exhibited at galleries all over the country and in private collections in Greece and across Europe.
