Mary Conroy RGN Specialist practitioner in General Practice and Accident & Emergency Nursing

Practice Nursing is my work and passion, I began my nursing career many moons ago. I trained at Hillingdon Hospital Middlesex (in the good old days of those amazing hats!). I qualified in 1979 and following this I travelled and worked in Canada. Upon my return to the UK I undertook a post-graduate training post in Accident & Emergency Nursing and in 1983 I took up a post as Sister in Kingston Hospital A&E department where I stayed for 4 years. I then worked for Marks & Spencers as Occupational Health Nurse in one of their large London stores. However, it all changed for me in 1990 when I started Practice nursing, to date I have 26 years of experience in General Practice. I have been with Chartfield Surgery since 2003. Every day brings new challenges but the great work that is accomplished is testament to the commitment of the primary health care multidisciplinary team.
