I want to express my utmost thanks to Dr John Crimmins for all the support and encouragement throughout my studies. The CBT content is extremely valuable — rich at an academic level but also deeply practical for everyday life. As well, they went above and beyond by providing extra reading links for those who are interested for more in depth research on particular data. My experience with the Institute was and still is positive and exciting.
