The leadership structure of Holy Trinity Parish includes several standing committees of the Parish Pastoral Council (PPC). 

These standing committees are:

• -  Committee on Ignatian Spirituality and Jesuit Identity;
• -  Communications Committee;
• -  Stewardship and Development Committee;
• -  Education Committee;
• -  Facilities Committee;
• -  Parish Life Committee;
• -  Social Justice Ministry;
• -  Worship Committee;
• -  School Advisory Board;

Role
The standing committees have primary responsibility for developing, coordinating, and overseeing the parish programs and activities meant to implement Holy Trinity parish's mission and pastoral plans, each in its particular area of concern. 

Each committee recommends an annual budget to the Finance Council for its consideration.

Membership
Standing committee membership consists of the Chair and three or more (depending upon the needs of the committee) at-large members (selected annually and expected to serve three years). In addition, the pastor appoints a staff person annually to each standing committee to assist committee members in their work and the Parish Pastoral Council Executive Committee appoints a liaison to the committee each PPC year.

To become a member of a committee, the requirements are to be a registered parishioner for at least one year, to be willing to make a commitment to carry out the duties of the position (minimally, this means attending meetings, taking on assignments, and making the required time for the commitment) and in addition, individual committees may set specific qualifications for membership.

Committee Chairpersons must be a confirmed Roman Catholic, and must have completed at least one year of membership on the committee. Chairs serve one year, with a maximum of two consecutive one-year terms.  Committees are encouraged to consider a system in which a Chair-Elect serves a one-year term and then becomes Chair after that year for a term of one year.

Meetings
Standing committees normally meet once a month or less, and meetings are open to the public. Meeting dates are listed on each standing committee page.
