Five new pastors in Nassau County

The Long Island Catholic has listed five new pastors of parishes in Nassau County (link HERE). These appointments by Bishop Murphy are effective June 29, 2016.  The parishes with new pastors are Corpus Christi (Mineola), Cure of Ars (Merrick), St. Martha (Uniondale), and St. Gertrude (Bayville). In what seems to be a change of titles, one priest will serve three parishes: pastor of St. Joseph (Hewlett) and Our Lady of Good Counsel (Inwood), and administrator of St. Joachim (Cedarhurst).

The list continues with the appointment of Associate Pastors at St. James (Seaford), St. Rose (Massapequa), St. Dominic (Oyster Bay), St. Ignatius Loyola (Hicksville), St. Barnabas (Bellmore), Notre Dame (New Hyde Park), Holy Family (Hicksville), and Sacred Heart (North Merrick).

St. Martha, Uniondale

St. Martha's church is located at 546 Greengrove Avenue, Uniondale NY 11553, telephone 516-481-2550.  This is a half-block north of busy east-west Jerusalem Avenue, and there is a traffic signal at the intersection.  The parish website is linked HERE, as of March, 2019.

Fifty years ago, when a religious congregation staffed a parish school, the pastor signed a contract with the congregation, which then appointed a principal and assigned the staff there as a "mission."  The pastor remained in control of the school, and he was responsible for its finances.
Referring to the above two photos, what was St. Martha's parish school is now used in part for the parish's religious education program (left or south end in the photo) and in part for St. Martin de Porres Marianist School.  The religious congregation founded in 1817 by Blessed William Joseph Chaminade runs the school, hires the teachers, and sets tuition and rules.  The school's address is 530 Hempstead Boulevard, Uniondale, NY 11553, telephone 516-481-3303.  Its website is linked here.

St. Martha's church is to the left of the photographer of the above two pictures, which look west. Hempstead Boulevard is a residential street to the right.  Busy Jerusalem Avenue is to the left.  On the west side of the school is Bedford Avenue.

From the website, it appears that four Marianists administer the school and that none are full-time classroom teachers.
