Activist Boniface Mwangi was in a buoyant mood on Tuesday as he celebrated his wife and mother of their three kids on social media.

Boni’s wife, Hellen Njeri Mwangi, turned a year older this week prompting the award-winning photojournalist to publicly gush about her on social media platform Instagram.

Mwangi, who recently launched his book ‘Unbounded’, described Hellen as the pillar of their family.

“Happy Birthday to this amazing woman who has supported me through ugali sukuma wiki, teargas and arrests. The pillar of our family, the mother of our three children and my number 1 supporter. Manzi wa maana, manzi wa nguvu, manzi wa power! Tutabidlisha Kenya pamoja. With her by my side we shall overcome any obstacles. She speaks COURAGE fluently!” wrote Boniface.
