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
I felt I needed help with regulating my metabolism. However doctor Muldoon concentrated only on my thyroid, something that my PCP has been doing for over 20 years. I will not be returning to this doctor
Providence Patient
Dr Muldoon's office is a welcoming place. The staff are friendly and very helpful. Dr Muldoon is a wonderful doctor. She is an excellent listener, and has worked with me to solve several problems that I was previously told "weren't really a cause for concern". I have been seeing Dr Muldoon for about a year, and she has solved a couple of long-standing medical problems. I have had very low energy for several years ( and was told I just need to exercise more), even though I was sleeping 18 hours a day because I could not stay awake. Testing my cortisol made a huge difference when we learned that my cortisol score was very low! I am significantly better than I was, and Dr Muldoon was a major part of that. Truthfully, all of my Providence doctors are fantastic! They have really helped me tackle/improve my quality of life! Sometimes it takes some searching, but they are all great and easy to work with!
