Dr is great,
Providence Patient
Dr. Muldoon is a good doctor. One of best doctors I've have gotten. I really like and appreciate that she takes her time with her patients and that her patients are able to have conversations about their health with her. Her open caring kind demeanor puts me at ease and makes me willing/gives me the confidence to talk to her about my health from asking her questions to letting her know my experiences with symptoms. When I tell her I'm not comfortable with taking certain medications and my reason I don't get the feeling of being judged in a negative manner. She takes what I say in consideration and talks to me about other alternatives. The things she say/suggests she always explain thoroughly and in a manner that's easy to understand. She doesn't rush like most doctors do. She actually listens and encourages you to talk. You have her attention 100%.

Providence Patient
I have a complex medical history having been hospitalized in 2013 with acute [ID] syndrome which led to strokes and permanent [ID] damage that has left me with long term side effects. Since COVID-19, my primary care doctor feels that I contracted [ID] and suffer with COVID- long symptoms. If I get sick, I need to see a doctor quickly. My primary care doctor instructed me to call him if ever I get really ill because he wants to treat me. Fortunately, I've only gotten sick a few times that I felt I needed to seek fast medical attention. When I call my primary care doctor to see him, I can't get an appointment for weeks! So, those few times when I did get sick ( once was with COVID), I had to seek either a virtual appointment or go to Urgent Care. These doctor visits were fine, but it's my primary care doctor that knows my medical history. He's the guy that I really should be seeing when I get seriously ill because he knows the intricacies of my everyday care to prescribe the best care to get me well again!
Providence Patient
Dr. Becky is very kind, always listens what I ask for. She gives me an advice.
Providence Patient
Dr Muldoon went above & beyond my expectations to suggest tests that are leading to finally getting answers to my health issues. I appreciate all that she is doing to get a diagnosis for me. She is an expert in her field and a very compassionate person. I feel that had I not seen her, I would continue to have problems.
