MediVa was founded and run by the late Dr. Njeri Muigai, a mental health specialist (consultant psychiatrist and clinical psychologist), who was involved in the promotion and practice of treatment and rehabilitation for substance use disorders, and other mental health issues. She had a special interest in working with adults and adolescents and a passion for community mental health.

Her legacy lives on through her colleagues at MediVa Wellness Centre, who in her honor continue to uphold what she believed in and endeavor to carry on her vision into the future.
