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

Four members of the current 17-member Mercy Education System of the Americas (MESA) Board have affiliations with Mercy High School.  MESA is the organization that supports and challenges the educational ministries of the Sisters of Mercy of the Americas. MESA governs, stewards, and provides oversight and assistance to the local boards of Mercy educational ministries in support of their students, parents, and educators.
Currently serving on the Board are David Levy, professor and MBA Program Director, Bellevue University, Omaha, Neb., and former Mercy High School Board member; Carolyn Jaworski ’64, alumna and retired principal; Christine Basque Malloy ‘87, Freelance Facilitator & Conflict Specialist and a former member of the Alumnae Council; and Carrie Potter ’95, alumna and President & Owner of The Carrie Potter Group, LLC, Houston, Texas. 

David was appointed to the MESA Board when it first began in July 2018. His wife, Mary Franco Levy ’70, attended Mercy. David has been a long-time supporter of Mercy and served on the school’s board for seven years. He is starting the second year of his second three-year term on the MESA Board.  

Carolyn served as principal of Mercy for 25 years. She is now in her third year on the MESA Board and has served on numerous Mercy educational committees including as president of the Mercy Secondary Education Association and chairperson of the Board for the Network for Mercy Education.

Christine joined the MESA Board on July 1, 2020, and will serve a three-year term. The alumna was a member Mercy’s Alumnae Council for six years, serving as president during her tenure, and worked in Creighton University’s Campus Ministry prior to her current position.
