She was born into the royal family of Nabongo Mumia in 1945 as the great-great granddaughter of the reknown chief. Being the last born girl of her parents Rhoda Lubanga and Japheth Obulumbi favored her and sent her to school in Kisa East where she had a passion for social work and community development.

In 1967, Dorina gained another title of “wife” when she tied the knot with Mr Wilson Anunda (Khwisero) in a colorful wedding ceremony at the Buruburu church of God and soon after had her children; Frank, Nixon, Beatrice, Hudson, Victor, Irene-Rhoda and Nelly.
The family built their first enterprise in Savanna as the family grew and grandchildren came in, whom she grew fond of.

In the year 2001, Mrs Anunda and her family built a school for the deaf in Sinai. With the help of her first daughter (Beatrice) they mobilized the community around to bring in their hearing-impaired children to get an education: a basic need. The school grew under the able leadership of Mrs. Doreen and her passionate children who helped around. In the year 2008 after the Post election violence, the school became displaced and a fire destroyed most of what they had in Sinai. When this occurred, Doreen went ahead to built her permanent school in Obama Estate-Nairobi.

The school grew and introduced a high school section, a preschool and eventually incorporated the new CBC system.

Mrs Anunda began to ail in the year 2020 where she was admitted for a leg injury at the Nairobi West hospital. Following a consultation with doctors and specialists she was diagnosed with varicose vein failure and later on had an amputation in late 2021. Later in 2022, her left leg began to have other complications and it was amputated as well. She had a total of 8 surgeries following further complications but came out pretty strong. She had her Mwanamke Bomba interview with Citizen TV later in 2023. Her health began to deteriorate in late 2023 again and she was admitted at the Avenue Hospital on the morning of May 15th, 2024. Mrs Anunda sadly passed away on 18th May after she got a cardiac arrest while undergoing treatment.

While undergoing treatment our loving mother had bills pending in various hospitals and clinics where the doctors and nurses were taking care of her.

We would like to call out to well-wishers and donors to help us give our loving mother a befitting send-off and support for her medical bills.
