The Pastoral Studies Institute of the Diocese of Tulsa is pleased to offer you many ways to learn about the Catholic Faith. Of course, we invite you to join us in person at any of our upcoming classes. Contact the PSI Office, (918) 307-4941, for a schedule of classes. We offer additional ways for you to participate online: pre-recorded audio and/or video, plus occasional live video. All of these online services are available to you free of charge.
