Vocation Story

Born and raised in the Chicagoland area, I grew up in a Catholic home with devout and loving parents. But, notwithstanding my parents’ efforts, I drifted from the Faith in my early teenage years, and I remained agnostic until my early twenties. I thought I knew what I wanted out of life, though after attaining my post-collegiate goals, I found I was still lacking a deep, interior happiness. This realization opened me up to again consider the question of the existence of God. Eventually I fully returned to Catholicism, and after receiving encouragement from priests and close friends, I began asking God if He was calling me to be one of His priests. Our Lord has since led me to enter seminary, and I look forward to seeing what is part of His Providence.

Priest Aspirations

My hope is to help others understand how Jesus holds them dear in His heart, and no matter what they do, He will always love them.

What has been your favorite/most memorable story of your time at Mundelein thus far?

As a new seminarian at Mundelein, I’ve been humbled by the charity and holiness of the men who have welcomed me. Entering seminary can be a daunting experience, but the joy and good cheer of the seminarians and formation team helped alleviate my concerns. I look forward to spending more time with everyone.

Anything Else

I truly believe that each person can become a saint, such is the great goodness and power of God.

How can Mundelein's donors and community pray for you?

I ask for prayers that I may become a good and holy priest, that I may never deny a request from Our Lord, and that I may entrust all of my actions into the hands of Mary and Joseph.
