Anna Prekas

Ms. Anna Prekas is our Facilities Manager and Parish Administrator. Anna has been involved in many of our parish ministries over the last few years and has now committed to help grow these ministries as a full-time employee and leader of our community.  In her new role, Anna will be coordinating and facilitating the work of our staff, our volunteers and ministry organizations within the overall framework of our parish operations.  While Anna works in our parish office, her role is not secretarial in nature. Anna’s job is to implement best practices and procedures throughout our parish operations and ministries. Therefore, as each committee and parish organization proceed to grow in its ministry, we ask that you coordinate with Anna in terms of the following:

  • Requests from our office staff such as reservations, correspondence, mailings, financial transactions, reports, etc.
  • Requests for facility use, available dates and times, custodial services, table set-up, instructions, fees and other requirements.
  • Maintenance issues throughout the facility.
  • Deliveries and use of various vendors and contractors.
  • Reimbursement requests, invoices and disbursements to various vendors.
  • Social media, e-mail lists, flyers, announcements, parish calendar, input for weekly bulletin and monthly publications.

In all these areas, Anna has offered to facilitate our parish in obtaining more efficient and well-coordinated ministries and parish operations. Please feel free to contact Anna via email.
