They didn't pressure us to buy anything we didn't need, It was years ago, and Dr. Swigert helped our daughter overcome a vision problem that was not diagnosed by her pediatrician in a "quick 20/20 vision test". When he could have kept us coming for the special eye exercises, once the progress that was needed was made there, he showed us how to keep the progress going at home, very inexpensively. Our daughter progressed 2 complete reading levels in 6 weeks. We appreciated his very thorough explanations of everything.
