SUGAR HOUSE HEALTH CENTER

I didn't learn anything new about my condition and received an allergy test that didn't really seem necessary. Many things were testing, like dog dander and pollen, when it's pretty clear from when I exhibit symptoms that those aren't a problem. I was told that if my asthma got worse, I could do more testing and switch medications, but wasn't told what the benefits or costs of those things would be, or how much worse it needs to get. Overall, I felt like the visit was a waste of money since seeing a specialist is expensive and they didn't enlighten me about anything.

UNIVERSITY OF UTAH MIDVALLEY HEALTH CENTER

I felt like she didn't want to get into too many details about my questions until a future appointment, but getting more answers would've helped me decide if I felt like it was worth having more appointments (and putting my young son through testing that would be scary for him). She wasn't able to give me solid numbers about chances for any of the questions I had which again makes it hard to decide how I want to proceed.

She (Dr. Duffy) is one of the most pleasant, calm & patient doctor anyone could have. She is very intelligent.
