Her professional work had both local and international dimensions. She contributed to training and capacity-building programs under international development initiatives.
NGO & Environmental Advocacy
Dr Nzilani was the Founder and Chairperson of Kibwezi Center for Sustainability, a non-governmental organization dedicated to environmental conservation, public health, education, and community development.
Through this NGO and her personal commitment, she was deeply involved in environmental activism: tree planting, wetland restoration, pollution control, raising awareness on sustainable land use, and community outreach programs. Her grassroots work earned her wide admiration and earned her the affectionate nickname “Syomiti”, meaning “tree/forest woman,” reflecting her image as a champion of green initiatives.
Public Service & County Leadership
In recent years, Dr Nzilani entered public service formally. She became a member of the county government of Makueni. By the time of her passing, she was serving as County Executive Committee Member (CECM) in charge of Trade, Marketing, Industry, Culture & Tourism for Makueni County.

Controversies and Criticisms
While Dr Nzilani’s reputation was largely positive, her career was not without public controversy.

Her comments sparked significant outrage. Many criticized the statements as disrespectful, sexist, and scientifically unfounded. Wildlife experts and medical professionals strongly condemned the claim, pointing out there is no evidence to support the theory that menstrual blood attracts crocodiles.
As a consequence, she was suspended for 45 days by the county government, with the administration clarifying that her personal views did not reflect official county policy.
In response, Dr Nzilani issued a public apology, acknowledging the adverse impact of her statements.
This controversy harmed public perception damaging her otherwise commendable environmental and developmental image. Nonetheless, supporters noted she had acknowledged the mistake and expressed regret.

- Consultancy fees and payments from advisory, auditing, and training contracts over her 17-year professional span.
