    Dr. Ellis is a true gem. Expert, thorough, kind and caring. She's helping me navigate several very difficult diagnoses. I likely won't live long with the cholangiocarcinoma, but she brings hope, and reassurance to each visit. When seeing her, I feel like I'm the only patient she has to care for. She's always up to date on the science, and has reviewed much of my workup at other institutions. I couldn't ask for better support.

    After my experience I considered myself lucky. Dr Ellis was sharp, personable professional. She was extremely positive and upbeat. Dr Ellis explained my situation and the possible processes/treatments that would be options going forward. She also explained were we were in that process, the timeline associated and the milestones along the way. She drew some illustrations to help me understand. Dr Ellis also included me and my thoughts in the conversation. I was totally impressed with what a sharp upbeat and engaging Doctor she was !!! I left the appointment feeling like I hit the lottery. I was lucky to have such competent and compassionate person in charge of my care. Quite honestly I feel I'm the only weak link in the team because it can be a little overwhelming meaning the illness not the people. I'm looking forward to our next appointment and know I couldn't be in better hand
