Colonoscopy Gastroscopy
Dr Jason Dunn took very precise care of me. From our initial consultation he listened carefully to my personal observations and enquired further to gain a wider understanding any possible consideration that may need to be addressed. He considered potential hereditary conditions that would be prudent to check. Through his guidance we decided upon an appropriate process of investigation. I feel that he had a very thorough approach that could be considered 'belt and braces' - which is certainly what a patient wants. His manner in explanation and care helped me feel that I was taken care of and issues that arose were kept in proportion but not belittled. His approach is both thorough and kind and one feels confidence in the careful approach he has.
