Coming into my first appointment, I wasn't sure what to expect and I was kinda nervous what I might find out. Dr. Kassim eased that anxiety from the get-go. I could tell by the start of the appointment that she really respected me as the expert of my body. She met me where I was at, helped me expand my GI health knowledge, and gave me honest answers that left me feeling empowered for asking questions. I left the appointment with more confidence in both my health decision making and my ability to talk about my GI issues with others. It's clear to me that she was always meant to be a physician, and I'm very glad she's my physician.
