Personal Statement...where did you get your help/pointers from?

Hey all, I'm a virgin to this whole posting a thread thing so this is my coming out party and hopefully I do it right. My question is regarding the personal statement. Who did you get help from in terms of having it reviewed for the content aspect? I know each persons statement is individual and has its own defining characteristics to why you want to be a dentist, but I want to make sure mine is I guess "good" as a statement. I've had my schools Health Professions director read it but she's brand new and isn't much into the whole Dental Application game. I don't want to go a head and start working on cutting characters and having grammar checked by teachers until I know the content is there. Any advice would be appreciated. If anyone would be willing to give my paper a quick once over for some feedback/advice, it would be even more appreciated (if thats acceptable). Thanks. Love this site.
