Mrs. Denise Corkery Marbach '72, P '05, '09 is the first President of Gwynedd Mercy Academy High School.

Denise Corkery Marbach ’72, P'05, ‘09 has over a 50-year history with Gwynedd Mercy. First as a Gwynedd student then as an alumna, a parent of two Gwynedd alumnae, and former Board of Trustees Chair, Marbach’s dedication and loyalty to the school and its mission have been a constant force in her life.

As head of the school, Marbach serves as the chief agent of change and innovation. She led the school’s strategic plan, “She is the Future,” and during the first four years of her tenure as the school’s first President, has instituted numerous programs to educate, inspire, and empower the young women of Gwynedd.

“Denise is an exemplary Mercy woman. She is an outstanding leader, committed to personal growth and social responsibility, and contributes to the development of others through mentorship and volunteerism,” said previous Board of Trustees Chair, Kathy Kirk Bellwoar '81. “Her life is an inspiring model of success through her work, talents and qualities of mercy and compassion.”

On her arrival in July of 2017, Marbach exclaimed, “I am very excited and deeply honored to be GMAHS’s first president. I am committed to the continuity of the school’s traditions and upholding our Mercy charism and Catholic beliefs. I am passionate about working with our faculty, staff, parents, students and alumnae to create our vision for the years ahead.”

Marbach was a partner with PricewaterhouseCoopers LLP (PwC) where she worked in the insurance, healthcare, and education industries for 38 years. A certified public accountant, she was the first woman partner at Coopers & Lybrand (C&L) Philadelphia’s office in its 90-year history. Price Waterhouse and C&L later merged to form PwC. Marbach launched and grew several new practices in major U.S. cities. She retired from the firm in June 2015.

Marbach serves an active leader in the community. She is a past board member of Faith in the Future, an organization focused on leadership, growth, and innovation in Catholic schools in Philadelphia, and currently a board officer of Inglis, an organization dedicated to providing ability and independence for physically disabled adults. She earned a BA in Accounting from Saint Francis University.
