- First woman in Kansas to receive a CPA certificate (1945)
- First woman partner of Deloitte and Touche of Kansas City
Mary Joan McCann was a pioneer for women in business, a leader in her catholic faith and an adult life long supporter of the Kansas City community. Mary Jo was born in 1920 in Iola, KS to Charles and Mary (Murphy) McCann. She graduated from the University Of Kansas School Of Business. She subsequently came to Kansas City and joined a local firm in 1942 and became the first woman CPA in the state of Kansas. Her local firm merged into what is now Deloitte and Touche. Mary Jo was the first woman partner of that firm and retired after 20 years as a member of the partnership.
She served in leadership positions in many organizations including the American Woman's Society of CPAs, Women's Chamber of Commerce of Kansas City, Siena Club, School of Business at University of Kansas, Finance Committee at St. Joseph Hospital, Missouri Society of CPAs, Board of Trustees at Avila College, and Administrative Council at St. Lawrence Catholic Campus Center. She was active in her faith through St. Peter's Parish, The Ladies of Charity and the Ladies of the Holy Sepulcher. Mary Jo's passions in life, in addition to her family and faith, were world travel and her Irish heritage. Mary Jo passed away in 2011 and will be sorely missed by those whose life she touched.
