Dr. Stier was kind, personable, and efficient but still willing to answer any questions I may have had. My procedure went smoothly and recovery was fast. Also shout out to nurses, especially Nate who assisted.

Dr. Stier never rushes you. He asks how you’re feeling. He exams your heart and lungs. He asks questions. He’s smart.

He was very kind and he explained everything perfectly about what we will do now and in the long run to try and treat my symptoms. He’s always able to answer my questions and works with me when I need a doctors note due to my chronic symptoms which I appreciate.
