When Dr. Kimbrough heard of the absence of African American dentists in San Diego, he hitchhiked to the city in 1935 and befriended the only Black physician in the area, A. Antonio DaCosta, who lent him office space in a rental unit. Dr. Kimbrough went on to become president of the San Diego NAACP in 1947 and the first president of the San Diego Urban League in 1953. Kimbrough accomplished much as an activist, including organizing a sit-in at the US Grant Grill in 1948 to protest segregation, and working to end racial prejudice.
