Pastor's Page

Welcome to our website. I am very excited with this improved way of communicating with our parishioners, our school families, and others interested in learning about St. Mary’s and the Catholic Church. I hope you will bookmark the website and all the pages and content that you like to check. One of the features of this website is this “Pastor’s Page.” It is like a blog in that I can update content on my own. I hope to, almost everyday, keep it current with new content. So, check back frequently. You can go to my e-mail link on the website and forward any comments or suggestions you may have. God bless all of you. Fr. LaHood
