I have a Degree in Business Administration and two Masters. First in RRHH and the other one in Help and Counseling.
I'm considere a person like to work with a kids because all my live i helped with they homework.
All my life i lived in Spain so my first language is Spanish. in my opinion is very important know different languages because can help you to have a good job or know differents cultures and differents persons.
