My 5 year-old son has been seeing Marianne S. for nearly a year for his Selective Mutism and Social Anxiety Disorder. Marianne is knowledgeable, kind and very efficient. She found and applied the right strategy (sliding-in technique) to address my son's developmental issue. Not all therapists are successful to deal with SM kids. After a few months of working with her, we have seen a lot of improvement with my son. I was more impressed with her when she liaised with my son's school and share with them the right approach to deal with my son's verbal and confidence issues, including convincing the teacher to do sliding-in session. We ended the school year with my son having a massive achivement talking to his teacher and friends and starting to build his confidence. Thank you to Marianne's hardwork, we are starting to achieve my son's goals and we'll continue to work with her this year for more amazing development in the future. 🙏😊 She is greatly appreciated and highly recommended!
