Patient verified via Press Ganey

Yesterday when I came to Dr. Williams's office for my follow up visit, I was very short of breath. She did a quick assessment on me and then sent me to the ER at Fremont Hospital. She is an excellent provider. She's very thorough. Her notes are very easy to read. She gives excellent directions. She's easy to understand and she's very compassionate. PROMEDICA is blessed to have Dr. Williams on their team of pulmonologist. And I am so grateful and blessed that she is my pulmonologist. I will always highly recommend her. I am a nurse educator and she's the kind of doctors that I talk about that that are just go above and beyond for their patients and she is one of them.
