Sr. Dee Leaving at the End of the School Year

On Wednesday, September 7th, Sr. Delores Hannon announced her resignation as president of Mercy High School to the Board of Directors effective June 30th, 2023. She has served as president since 2009, having served for 14 years.

Sr. Dee, as she is affectionately known to students, faculty and parents, has overseen many changes at the school. The school facilities have experienced improvements with The Hannon Center for Academic Success, heating and cooling systems, new lockers, bathrooms, a dramatic facelift to the front offices and entryway, to name a few. By the time Sr. steps down, most of the school will have gone through some sort of renovation. Mercy High School has also experienced growth in their academic reputation. “One of the things I’m most proud of is the expectation that our students will be readily prepared for college” Sr. Delores explains. “We’ve expanded our counseling and SAT/ACT preparation, while faculty and staff have increased the expectations of what our students are capable of accomplishing. I have a very strong faith that the Mercy spirit continues to thrive through our students as they serve in their respective communities.”

Sr. Delores  has been an educator for more than 40 years. She grew up in North English, Iowa on a mixed livestock farm, the only child of William and Mary Hannon. She joined the Sisters of Mercy in 1969 and quickly was tapped for leadership in schools. She became a principal at St. Matthew’s Grade School in Kalispell, Montana, in 1978 followed by a short stint at Our Lady of Grace School in Edina, Minnesota, from 1981-1983. From 1983-1995 Sr. Dee was the principal at several grade schools in Iowa. She moved on to serve as the Vice President of the Sisters of Mercy in Cedar Rapids, Iowa, and the President of St. Edmond Catholic School in Fort Dodge, Iowa before ultimately coming to Mercy High School in 2009.

The Board of Directors will form a search committee to begin the search process in the near

Living a Life of Service 

July 24, 2020
By Deb Daley

Anne Mollner Stanley ’05 found her love of service while she attended Mercy High School. Now she serves as the Regional Director for Ignatian Volunteer Corps in Omaha.  It is a volunteer organization  for individuals over 50 who are looking to use their talents in service for non-profits in the area while participating in a faith community.  These individuals serve about 8-10 hours a week at various organizations throughout the city and gather together once a month for reflection and faith sharing. 

Anne considered Mercy on her short lists of high schools because her mom, Jayne Riedmann Mollner ’70, aunts, Margie Riedmann Sobczyk ’67, Mary Pat Riedmann Greene ’73 (deceased) , Kathleen Riedmann Kemler ‘78, and Francie Riedmann Weis ‘81, and sister, Katie Mollner Baumker ‘94, attended the school.  But at her first visit, she knew it was the place she belonged.

“I knew it was a place I would be comfortable being myself.  It was filled with so much welcoming energy,” she said. 

During her years at Mercy, Anne was involved in theatre, Student Council, Pastoral Council, National Honor Society (NHS), and many service activities. 

“The school had a major impact on me, and I often attribute both my path in life and who I am to Mercy.  I truly believe Mercy gave me confidence and welcomed me into a community of people who truly celebrated who I am.  My love of service was also instilled in me while attending school.  Thanks to the incredible teachers of Mercy, I also developed a passion for Spanish and journeying with others through service,” she said. 

After graduation, she attended Franciscan University, Steubenville, Ohio and majored in Spanish.  She did a year of service in San Diego and Tijuana, Mexico.  Anne went on to get her Master’s in Education from Creighton University in 2013.  She taught Spanish for five years at Mercy from 2014-2019.

“The young women that attend Mercy continue to be some of the kindest, funniest and most creative young people in our community,’ she said.

According to Anne, the organization she is with now pairs faith and service together, two foundations of Mercy education.  The job allows her to grow in spirituality while helping others and working with non-profits across Omaha.

“It is beautiful to see so many in our community working together to better the world around us,” she said.

Anne continues to talk to the teachers and follow along with what students are doing.
She tries to attend both alumnae events and school activities such as Mercy Day and P.A.

“I love keeping up with Mercy.  The school does so many things.  I would encourage alumnae to participate in the ways Mercy invites us to reach out to current students by writing letters, watching events, and celebrating the successes of the girls,” she said.
