In 2003 Dr. Zajdlik was the only HIV physician in the area and with an HIV patient roster rising to over 70 patients a friend and fellow colleague encouraged her to open a regional HIV clinic. It would be 14 months later that she received government funding.

On September 15, 2005, with the support of the community and unprecedented media coverage The Masai Centre for Local, Regional and Global Health opened its doors and now serves over 300 patients. In order to provide more accessible care to this large region of the province, The Masai Centre opened it’s Masai Satellite Clinic in January of 2010 in Waterloo, Ontario complementing the clinic in Guelph.

The Masai Centre for Local, Regional and Global Health is one of several community-based HIV outpatient clinics in Ontario funded to provide care and treatment for those living with HIV/AIDS in the Wellington-Dufferin, Grey-Bruce and Waterloo Regions. Clinic Staff help people living with HIV/AIDS address the many complex health and social/emotional needs they face. The clinic service model is based on a compassionate and holistic case management approach to care and offers access to a range of services including medical/nursing care. Educational, psychosocial and social services support are provided by the AIDS Committee of Guelph and Wellington County (ACG) and The AIDS Committee of Cambridge, Kitchener, Waterloo and Area (ACCKWA). The clinic is client and family centered and emphasizes a continuum of care.
