Sister Sienna Cameron spent 12 years teaching at schools across the Diocese including St. Augustine, Rochester; Holy Rosary, Rochester; Corpus Christi, Rochester; St. Mary, Waterloo; and St. Alphonsus, Auburn. After teaching, Sister Sienna went into secretarial support services which included working in the SSJ Public Relations/Communications Office.

“Sister Mary John Van Atta and I did our own photography, from picture taking to developing; content and layout of publications; and updating the Congregational ‘Mug Book,’ a photo album of all our Sisters,” recalled Sister during her 60th Jubilee celebration in 2023.

She later joined the staff in the Social Ministry Department for the Diocese of Rochester and eventually served in the SSJ Motherhouse Services ministry.
