In 1892, she obtained the Triple Qualification, becoming a Licentiate of the Royal College of Physicians of Edinburgh, the Royal College of Surgeons of Edinburgh and the Faculty of Physicians and Surgeons of Glasgow. She was appalled by the standard of care and lack of specialisation in the needs of female patients, and was able to obtain a post at Elizabeth Garrett Anderson's pioneering New Hospital for Women in London, and then at the Rotunda in Dublin, a leading maternity hospital. Inglis gained her MBChM qualification in 1899, from the University of Edinburgh, after it opened its medical courses to women. Her return to Edinburgh to start this course had coincided with nursing her father in his final illness before he died on 4 March 1894, aged 73. Inglis at the time noted that 'he did not believe that death was the stopping-place, but that one would go on growing and learning through all eternity'.
