The best way to find a good and genuine psychic is to ask around. Ask your friends if they have ever had a good reading from someone.
Also go to your local metaphysical or New Age shop and ask the owner if they can recommend someone. The usually know all the good psychics.
I'm a Pet Psychic Medium and I have a friend who is a people psychic and we both worked at Live Person which is like Keen. You can find some genuine psychics at places like that, but it runs into money as they charge by the minute...that is why we both left. It didn't seem right. Check ebay and look at feedback too. Avoid people with names like Lady this or Isis that. Usually a good psychic will use their real name. Hope this helps.
