Adrian Dominican Sisters, associates and friends gathered to honor Sister Mary Catharina Bereiter, OP  and celebrate her 100th birthday during a special gathering April 20 at the Adrian Dominican Sisters Motherhouse.

Sister Catharina professed her final vows as an Adrian Dominican in 1950. In 1964, she became a professor at Siena Heights College (University) in Adrian. In 1974, Sister Catharina served as the religious education coordinator at Holy Family Center in Adrian for two years before moving to inner-city Detroit, where she served in a variety of ministries for nearly 40 years. Sister Catharina retired in 2014 to the Dominican Life Center and continues praying for the people of Detroit and the sisters of her community.
