I highly recommend this pulmonologist! She was VERY thorough, and really took the time to listen to my symptoms and history. She was very compassionate as well. She returned all of my calls promptly and as soon as tests results were back to her. She promptly referred me to Dr. Leyla Best for treatment when she suspected that I had histoplasmosis and she is awesome as well! Dr. Guest is the cream of the crop! I wouldn't hesitate a moment to refer anyone to her.
