Thongori was born in 1964 or 1965. She was educated at Kahuhia Girls' High School for
Ordinary Level (O-Level) and Advanced Level (
A-Level). Thongori was married to another lawyer, John Thongori, with whom she had two children. She started her own law company, and she became an advocate for women's rights. She saw that the Kenyan police ignored abuse cases where the woman and family relied on the man's income. She realised that the culture was at fault. She organised training sessions for the police to inform their actions. Thongori spent five years leading an association of women lawyers. She was recognised by the Institute for Inclusive Security and Thongori's highest profile case was when she won a case against the Kenyan government when they failed to deliver 30% representation for women. In 2015 she was chosen to be one of 21 women who met for a conference at
Harvard University Kennedy School of Government funded by Hunt Alternatives. The group included
Fauzia Nasreen from Pakistan and
Olufunke Baruwa,
Esther Ibanga,
Hafsat Abiola and
Ayisha Osori from Nigeria. In 2023 she joined a committee to look at the activities of radical religious groups formed by President
William Ruto. The committee of seventeen was formed following the
discovery of over 170 bodies in the Shakahola Forest. It was said that followers of a church in the
Dagoretti Constituency were encouraged to starve themselves to "meet Jesus". Critics said that Ruto had chosen "insiders" to investigate. ==References==
