Father Helwig Names New Principal for 2018 2019 School Year

After interviewing several qualified candidates, Mrs. Mary Jo Pronio has been selected to lead St. Margaret Mary School as its new Principal, beginning July 1, 2018. She succeeds Mrs. Fennessy, who tirelessly and with steadfast commitment, served the school over the past 9 years as Principal.

With grateful hearts we thank Mrs. Fennessy for her years of dedication to the school community and wish Mrs. Pronio the very best as she assumes her new duties.  May God bless them both in the future and continue to guide St. Margaret Mary School in its mission of educating young people along the pathways of knowledge and the ways of the Catholic Faith.

In Christ,
Father P. Helwig

Mrs. Fennessy Accepts New Teaching Assignment at STMM

SMMS Principal-elect Announcement:  With my recent change of employment at St. Margaret Mary School, from Sixth Grade homeroom teacher to Principal, the vacated position needs to be filled. As my first administrative act as Principal-elect, I have asked Mrs. Fennessy to assume these duties and she has accepted. Mrs. Fennessy will begin her new duties on July 1, 2018. It is a great pleasure to know that Mrs. Fennessy will continue to be an important part of the SMMS family.

May God bless everyone with a relaxing and safe summer.
