Real Stories from Real Montanans
Three incredible women, Nancy, Betty, and Patti, share their stories of how pulmonology care at Great Falls Clinic helped them breathe easier and live stronger.
“She [Dr. Sisk] was so kind and patient with me. We just talked like old friends before I left her office. It’s like going home to me. Everybody knows me—they call me by my first name. I’ve had such a wonderful experience with Great Falls Clinic. I wouldn’t go anywhere else,” shared Betty.
“Every Day, Every Year is a celebration for me. The teamwork has been phenomenal. It is really comforting to know that the professionals on my team know what the other ones are doing and how they are trying to help me,” shared Nancy.
“At the Great Falls Clinic, the team that Jason works with makes it all so easy. From the time you check in, until a nurse comes in to take your vitals, and ask you questions, until you go back and get an appointment—it makes it very easy,” shared Patti.
