I'm former RN, formerly worked with lots of surgeons. Now I'm old lady, too many medical issues. Dr Casillas is the best of the best. Very thorough in his exam, review of my medical history including extensive review of my chart, display of anatomical model to review my issues, suggested course of surgical treatment and recommendation genetic counseling consult d/t sister expiring of pancreatic cancer. He was thorough, compassionate and clear in his recommendations for future treatment. Presented me written info r/e my diagnosis, suggested treatment including post op instructions to visualize self after care. He is a role model for how all office visits and practioner visits should be. He is a strong asset for UT Knoxville.
