Person I know seems like a pathological liar but doesn't have any symptoms etc?

I'm not going to say who it is but they basically lie to me a lot, it's not random lies like a disorder but many times we've discussed their issue and they are still struggling to overcome lying. It's always the same situation as well and he says he lies because he doesn't want me to get mad but i've overcome my anger, i'm not getting angry at him anymore yet he's still doing it. I did some research and he doesn't seem like a pathological liar, except for the BIG fact that he doesn't think of the consequences, how it would make me feel, he's actual figured out how to make me believe him and he just can't stop. I want him to overcome lying but I can't help him if this is a disorder. I need to know, What professional could help me here?
