Hola! Mi nombre es Ana y me encanta la enseñanza y poder compartir mis conocimientos. Estudié biología y posteriormente me doctoré en Ciencias Biomédicas. Comencé dando clases particulares durante mis años de estudiantes y ahora, me dedico 100% a ello. Tengo estudiantes de todos los niveles, desde primaria hasta universidad, con muy buenos resultados. Me gusta no solo que el alumno aprenda la materia sino que también tenga mayor seguridad en sí mismo, sepa organizarse y tenga confianza. Estaré encantada de ayudaros.
