Dr. Ewa and her IdealMe workshop is the best therapy I have ever had for my son (10 yo), and I tried quite a few, unsuccessfully. She was able to change his attitude and his outlook, he is just a wonderful boy now, kind and gentle. Complete turn around. No more problems. Thanks Dr. Ewa. I recommend this workshop to anybody. 10 stars!
