[1] Her story is part of the Scotland-Malawi partnership and the strong relationship between the two countries, providing service for the under-serviced hospitals in Mulanje and Ekwendeni.

Mantell was best known for her significant contribution to the development of the Ekwendeni Nurses' Training School in Malawi, practicing holistic care, and being one of the pioneering female medical missionaries of the latter 20th Century.

[4] She was a member of Macduff Girl Guides, sparking her love for the outdoors and gaining skills for her future endeavours in Malawi.

During her time at the Church of Scotland, Mantell took on the leadership role of ordination to eldership of Kirk Session, served as representative elder to Buchan Presbytery, and led teen Bible classes.

[10] This was a prime example of the importance of holistic care to Mantell, as the group taught girls to appreciate their faith in addition to learning nursing skills.

After growing up as a young girl in Africa, Mantell had fond memories of her time there and was eager to return to her country of birth.

Additionally, she felt the call of God while working in the Aberdeen Royal Infirmary, seeing it as her religious duty to aid the sick in Africa.

Following a semester at St. Colms, in 1966 the Church of Scotland's Overseas Council sent Mantell to Mulanje, a town located in the southern region of Malawi.

These talks included slides, visible in the National Library of Scotland, on her work in Malawi covering schools, church, nurses, and visits to Zomba.

During her many years as a missionary, Mantell became an active member of CHAM Training Committee, the Nurses Council of Malawi, and the Ministry of Health.

[2] This would turn out to be a terminal illness, sparking her return to Scotland for chemotherapy treatment at the City Hospital in Edinburgh and the Aberdeen Royal Infirmary.

[19] With over 300 students enrolled today, the school produced by Mantell's vision provides an opportunity for employment and increases the number of medically trained staff in Malawi every year.

[20] The current mission statement of this school closely aligns with Mantell's principles, “Ekwendeni College of Nursing through excellence in teaching and learning environment shall train/educate and inspire students in the nursing and midwifery profession within the Christian principles.”[20]On 22 April 1998 the Macduff Parish Church dedicated a stained glass window to Mantell.
