Quintero Lopez was born in Vijes, Valle del Cauca, Colombia on 6 March 1910, although he claims to have been born on 15 March. He was the son of Rosenda Quintero, who was single at the time, and that’s why he have his mother’s last name. His grandmother was Zenaida Quintero. He worked as a blacksmith.

They have lived together ever since Quintero Lopez became a widower in 1962. At 108, he was mentally sharp and could still walk with the help of a cane. He celebrated his 110th birthday in March 2020. At that time, he had two living daughters, Oliva (born in 1935) and Enith (born in 1943). He also had 13 grandchildren, 12 great-grandchildren, and eight great-great-grandchildren.
