Who We Are


Here's a brief introduction to the great folks who work at PRISM:


Scott Boyd, director of PRISM since 2002, oversees the staff and interns. You can meet Scott at PRISM's following events: Open House, weekend hosting, and any other special events. Scott is married to Lisa, and they have four boys. His family enjoys playing sports and traveling. Ask Scott about his adventures biking from St. Louis to Boulder, Colorado, and from Boston to Montreal, Canada.







Cori Hill, administrative assistant at PRISM, manages donor relations, mailings and other communications with Americans and Internationals. Her husband's name is Mitch and they have two boys. In her free time, Cori runs, bikes, hikes, camps, and builds LEGOS with her family as well as enjoys sewing & crafts. She and her husband have hiked Mt. Washington in New Hampshire. Cori also enjoys gardening and watching her two sons grow up!







Christa Saenz helps coordinate PRISM's weekly events and activities. You can find Christa each week at Open House, Bible Studies and many other weekly activities. She has recently rediscovered her love for good books, good coffee and having recently gotten married, is enjoying learning how to be a good wife. She got to see a good portion of the United States when she traveled in a motor home with her family for five weeks when she was nine. Since then she has traveled to Honduras, Ghana and Uruguay. Ask Christa about her six week adventure through Europe!






Melisa Del Castillo is from Colombia and she helps to organize PRISM's activities, church visits, women’s ministries, relationship building and more.  She has her master’s degree in Industrial Engineering and worked as a teacher and researcher at the University in Barranquilla, Colombia. She has 14 years of experience in Research and Consulting Projects. She first came to Pittsburgh after her husband moved here for research, and was drawn in immediately by the warmth and community found at Open House. Melisa likes to learn about other cultures, traditions and worldviews. For fun she enjoys cooking new dishes, travel, and being in nature - including snorkeling, scuba diving and swimming.






Bethany Loosararian leads PRISM’s marketing and communications as well as helping plan special events and activities. She has earned a degree in marketing management from Grove City College where she played soccer and developed her true love for learning. In her free time, you can find Bethany doing anything outdoors-related, working in a coffee shop or playing tennis with her husband. Bethany enjoys learning about and experiencing different cultures and understanding worldviews.








David Zamora is part of the Colombian invasion to Pittsburgh (he arrived at the city in 2015, with Yina, his wife). You will see him in different PRISM activities, either wandering about with a yellow camera and a tripod or helping to move heavy stuff. David also supports Spanish Bible studies, English conversation groups, and M28 groups. He enjoys various types of narratives (e.g. short tales, classic novels, films, and comics). Ask him about his year in Wales, that time when he was offered to eat monkey and armadillo in the Amazon, and his favorite soccer team!
