My clinical role is varied, offering a range of clinical care such as contraception services, including coil and implant fittings, all of which I am passionate about. I am involved in managerial aspects of the nursing team and was previously the student coordinator. I enjoy teaching, supervising, and supporting students/clinicians during their training here at Jefferiss.
