Dr. Kass is always supportive of my needs and anxieties, and is kind, and caring. I ask a lot of questions and Dr. Kass offers answers with the right degree of detail. He tells it like it is but tempers it with consideration. I like that. Recently he called me at home during my chemo treatments to see how I was doing, and offered his personal cell number for me to call if I needed to talk to him. It was nice to talk to him. It's a real pleasure to have him as my pulmonologist. Dr. Kass has made my IPF and my lung cancer treatment journey go well so far.
