I am a fortune-teller by trade. Having heard about DIO's evil from Mr. Joestar, I knew exactly who he was when I encountered him in my shop back in Cairo, so when Mr. Joestar's daughter, Holy Joestar, awakened a Stand that she would eventually die from, I joined that journey to defeat DIO and lift the curse. I have met many Stand users in my life, many of which we have encountered as servants of DIO on our travels.
