Cronk worked for the National Health Service in the UK where she facilitated more than 1600 births, mainly as home births. In 1991, she opened her own practice and started working as an independent midwife. Cronk joined the English National Board of the
United Kingdom Central Council for Nursing, Midwifery and Health Visiting, and served on the
RCM Council between September 1999 and August 2003. Cronk also wrote many articles on
midwifery, covering a variety of topics, including physiological
breech birth, of which she was a proponent. These have been published in Midwifery Matters and AIMS Journal, as well as quoted in various books. Once retired, Cronk continued to educate by hosting study days alongside fellow independent midwife Jane Evans; the pair disseminated information on unusual but normal births, including breech birth. ==Obituary==
