Meet The FOCUS Missionaries


FOCUS Team Director

Caitlyn Irving

My name is Caitlyn Irving and I graduated from the University of Vermont in 2016. I had a life changing encounter with Jesus in the Eucharist my freshman year of college and my life has never been the same. Growing in my relationship with God is the center of my life and it is such a gift to get to share the treasure I have found in Christ with others. I am excited to serve as the FOCUS Team Director at MIT at his year and to get to know and serve the TCC community.


John Ortega

I am John Ortega, and am a second-year missionary with FOCUS. I hail from The Land, Cleveland, Ohio, and I graduated with a Bachelor's Degree in Health & Societies (Public Health) from the University of Pennsylvania. I have used my degree to do research on Catholicism in health as well as to research the "Newman Movement" -- the history of Catholic centers at secular universities like MIT. I am a proud Filipino, and love to partake in cultural events and activities! I also am a photographer (Let me know if you ever need some photos!), and have a general interest in the Visual Arts, especially cinema! One of the greatest joys of my undergrad was working with my Newman (Catholic) Center at Penn, working with students to grow in their relationship with Christ and spreading that love, heart-to-heart, with others. If you ever need someone to talk to, shoot me a message!


John Bartee

I’m the other John on team MIT this year and I’m a first-year missionary from the great state of Texas! While I’m originally from the Houston area, I attended the University of Dallas, a Catholic school where I majored in Spanish and psychology. One of my favorite things to do is travel and I’ve had a lot of chances to go to some really cool places in the last few years, so if you’re ever curious about my summer working in Alaska or my time studying in Rome, please ask! Most of all, I’m excited to be a missionary disciple of Christ Jesus and to share the life and love he’s given me with the students at MIT. Shoot me an email if you want to get involved with FOCUS on campus!


Maddy Pereira

My name is Maddy Pereira and I am a first year missionary from Ludlow Massachusetts! I graduated from UMass Amherst with a degree in Psych with Pre Med studies, and worked in an emergency room! I am looking forward to leading bible studies, sharing the faith with students, and perfecting my Portuguese coffee making skills! I love going on walks and exploring Cambridge and Boston, so please reach out if you would like to hear more about the beauty of Christ’s love for us and how the faith has changed my life!

Heidi Zamzow

HELLO!! My name is Heidi Zamzow and I am from Minnesota!  I graduated from the University of Wisconsin – Madison in May 2020 with my bachelor’s degree in nursing.  I then worked for a year as a registered nurse before the Lord called me to be a FOCUS missionary! Through my time in college and the past year working as a nurse, I have completely fallen in love with Jesus Christ and His mission! My relationship with Jesus has 100% changed my life and I am still amazed every day at how much joy, freedom, and peace He has brought me! I am so excited to help bring this love to the MIT campus and to meet everyone at the TCC! It’s going to be a great year!
