The speaker is Sue Holden. Her website says this of her -

Past lawyer, present entertainer and (aspirational) future public speaker – I seek to inform with humour. I have been entertaining people for as long as I can remember. I worked as a lawyer for slightly less a time, (36 years.) I have enjoyed a fulfilling and interesting career and have a passion for learning. The law is something that touches and confounds us all from time to time and in my professional life I strived to convey both my enthusiasm and learning. In my retirement I seek to couple my interests to bring you an entertaining insight into the law.
