This obituary is part of a series about people who have died in the coronavirus pandemic.

In 2005, Antonio Checo became a mental health clinician at Mt. Sinai Queens hospital, one of his many jobs devoted to helping people.

And it was there, on April 1, that he died of complications of the coronavirus at 67.

In the intervening years he was ordained a priest and became the rector of St. Mark’s Episcopal Church in Jackson Heights, Queens. As the Very Rev. Antonio Checo, he spent many of those years working full time in the church and at the hospital, allowing the practical service of his social work to inform his ministry.

The Rev. Jason Moskal, the deacon at St. Mark’s, confirmed the cause of death.

Father Checo took over St. Mark’s in 2009, when the congregation had dwindled to about 20 members. He helped revive the church, which now has a congregation of about 180 people. His parishioners included African-Americans, Latin-Americans, white people and immigrants from South America, the West Indies and the Philippines.

Father Checo enlarged the church’s food pantry, emphasizing staples like rice on which people in his neighborhood relied; conducted two Sunday services, one in English and one in Spanish; and did his best to ensure that his parishioners were able to navigate New York City’s bureaucracy to receive the help they needed.
