Dr. Isaac Betech is a pediatrician in Mexico. He is very active in Jewish outreach, in collaboration with Rabbi Yosef Yagen of Monsey. By his own admission, he was instrumental in getting several Gedolim to sign a letter of condemnation against my books. According to someone in Mexico who wants to translate my books into Spanish, he would be unable to distribute them in bookstores due to Dr. Betech's influential opposition.
