Nzilani Glass Conservation is a highly specialized stained glass conservation company with over 25 years of experience in architectural preservation. Nzilani creates new art and provides safe, museum-quality art conservation for the public.

Our core values are “Be Safe. Have Fun. Do Excellent Work.” We lead the industry in best practices for employee protection from lead exposure while working with stained glass, and believe that being aware of your environment and materials frees you to do your best work and have fun while doing it.

The company’s in-house documentation services allow it to reach a wider audience, through professionally produced videos, surveys and treatment reports. Company Founder, Ariana Makau’s approachable and non-judgmental style is well received in classrooms and public talks. Her presentations at national conferences bridge the gap between health & safety regulators and those in the stained-glass industry. Attendees leave with a better awareness of what is necessary to protect their own personal safety when working with stained glass as well as a better appreciation of the art form.

Nzilani adheres to the AIC Code of Ethics as well as the Secretary of the Interior’s Standards of Preservation. Recent awards include a California Preservation Foundation Award in Preservation Design for our Work of the Monumental Stained Glass Windows at Grace Cathedral in San Francisco. Makau is a Board Member and the Health & Safety Chair of the Stained Glass Association of America, and holds a Masters in Stained Glass Conservation from the Royal College of Art, London, England.
