“Your consultant is not only very nice, but also extremely competent and committed, and she conveys the principles of ABA very professionally, clearly and structurally, and knows every answer. After attending the workshop in Kaiserslautern, I was able to teach my son his first sign according to the ABA rules. He now seems relieved that he finally found a way to communicate. Thanks to your consultant, we have now come a long way and were surprised and delighted how much my son got involved in the game and was ready to solve small tasks. We are very hopeful that we have finally found the right path for him and can take him a step forward in his life. “
