Katerina worked for my website for two years, the first year she had a column where she answered questions related to children's psychology. The aim for us was to offer help to parents that want to raise their children with high quality standards. Katerina was excellent on explaining what they needed to do to have efficient results. The questions were sent to my website from the parents and every 15 days we were publishing two questions with Katerina's educational guidelines. To work with her was a privilege, all readers were very excited.
