Rev. William E. Brown – Pastor

Reverend William E. Brown, Pastor

William Eugene Brown was born February 10, 1959, in Los Angeles, California, son of Eugene Fetscher Brown and Mary Jane Brown (both deceased). He was baptized, confirmed and received First Communion at age nineteen in Pella, Iowa, during his freshman year of college.

Father Brown spent the later part of his childhood in the mountains of the high desert, at Lake Elizabeth, CA, where he first felt a call toward God. He left home to attend college in Iowa, and after going to Mass for the first time in his life, approached the priest and announced, "Father, I want to become a Catholic!" This dream came true at the Easter Vigil the following year.

As a German and French major in college, he then spent one year in Austria (at the University of Vienna), and one year in France (at the Sorbonne), enjoying countries that had such a long and deep Catholic history. He felt a tug inside toward the priesthood, but never had the courage to ask anyone about it until he was back in the United States, pursuing a doctorate in German Literature at Stanford.

The priests there at the Newman Center (Fr. Dennis Browne and Fr. Eugene Boyle) were a real blessing, helping him discern his call, and encouraging him to enter St. Patrick's Seminary in nearby Menlo Park. The four years of seminary were a great delight and a challenge for Father Brown, helping him grow in the Catholic faith and look forward to serving Jesus and his people as a priest.

Since ordination, he has served at the following parishes in our archdiocese:

• St. Elizabeth, San Francisco (deacon year)
• St. Gabriel, San Francisco (six years)
• St. Pius, Redwood City (four years)
• Our Lady of Mercy, Daly City (twelve years)

Favorite Quote:

Nothing is more practical than finding God,
that is, than falling in love
in a quite absolute, final way.
What you are in love with,
what seizes your imagination,
will affect everything.
It will decide
what will get you out of bed in the morning,
what you will do with your evenings,
how you spend your weekends,
what you read,
who you know,
what breaks your heart,
and what amazes you with joy and gratitude.

Fall in love,
stay in love,
and it will decide everything.

– Pedro Arrupe, SJ
