About Us


    We are John and Mary McClernon current Third Order Dominicans living in Oklahoma. We love our Lord and want to share what we have found to be the fastest, surest, and simplest way to reaching Him.

      Our Father in Heaven has given us each other as companions. What a Blessing and joy our holy marriage has been. It has been filled with Joy, tribulation, and most especially LIFE.  We have 6 children now (our daughter was married in 2015 adding 1 more son to the clan).

      We have also discovered what wonderful, helpful, spiritually wise, and consoling friends we have in the Saints! They have inspired us to create many of our products.

      Our business - Summa Enterprises, Inc. began with our first Rosary/Saint CD "Praying the Rosary with St. Therese of Lisieux" and has since grown to 7 CDs, 8 books authored by John, and 1 DVD. 

      We travel to Catholic Conferences around the country to share our products. We are also available to give talks on some of the Saints that inspire us (St. Therese of Lisieux, St. Maria Faustina, St. Thomas Aquinas, Our Lady of Medjugorje, St. Catherine of Seina and others)  I truly believe we have found the future of the church at these conferences and retreats.  Feel free to contact us with any questions or if you saw something at a conference that I don't have on this website.
