Welcome from our Principal:

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.

We encourage you to search our website for more information, call and arrange a tour to visit, or contact us with any questions.  If you are an alumna of St. Sebastian, we would love to hear from you, what you are up to, and any reunion events we might help communicate in our Alumnae section of this site.

Thank you and God bless you,

Ms. Heather Grams
