Welcome to our community!

As a parish school since 1913, the St. Sebastian community has served as a pillar in the Washington Heights neighborhood and the Milwaukee area, providing students with a strong faith foundation, solid academic preparedness, and effective skills in community-building for over 100 years.

Our school theme for the 2017-2108 academic year comes from Hebrews 12:1a-2b and proclaims, “Let us run with perseverance the race marked out for us, fixing our eyes on Jesus”.  Together with our students, staff, and families, we will further explore and strive to live out this theme throughout our year.

We encourage you to search our website for more information, to call and arrange a tour or visit, or to contact us directly with any questions.  If you are an alumna of St. Sebastian, we would love to hear from you!

May God bless you always,

Ms. Heather Grams, Principal


All Saints Day, November 2017
