Dear Dr Kallis, we just wanted to write to you in person to say thank you for everything you did to care for our Dad, Andrew, both in getting the hospital to take his case seriously and your advice during his final days. We also wanted to mention and say thank you to your team and in particular Dr Alex Zissimopoulos, her care for Dad and her patience with our many questions was was a great comfort to us all. Thanks again and all the best with the great work you do.
