Client Case Study

"When I was 15, my Father showed me a photograph of a boy and told me it was given to him by the boy's mother who implied that he was my father's son! The instant I saw it I knew that this boy was my brother. I waited until I was an adult to make my search. Ten years later, I finally found my little brother. But I had to get my family as well as my father to accept him. I came across DNA Worldwide, got my father and new brother to perform the quick, easy procedure, and two weeks later, I could finally prove to the world what I already knew."
