Just one point to clarify:<br /><br />You wrote "a family of four," which implies your parents and two children.<br /><br />Then you&nbsp;mention four children&nbsp;(three sisters and you)&nbsp;so that's a family of six.<br /><br />So I wrote the following:<br /><br />"I&rsquo;m the youngest in a family of four children. Healthcare and leadership run in my family. My mother was a nurse, one of my sisters was a nurse, and another sister is a radiologist, while another is a retired administrator."
