National Jewish Health Patient – August, 2024
I am pretty sick with a lot of different health issues. I can do doctors appointments in my sleep. I'm fully disabled so being sick has essentially become my job. I've worked with doctors all over the country so I feel my experience holds more weight than other people who may only have a few doctors. My sleep doc is out of the office and everyone there is always kind and easy to speak with. My new pulmonologist and her nurse are no different. I was impressed when she told me her plan. It is very aggressive and knowing my experience with my own health, she explained using full medical jargon. She listed tests, bloodwork, other physicians she wants to bring in to this, scans, and set expectations that not until tests are completed and results are in could treatment options be discussed. I'd rather be healthy, but if I have to be sick, I'm glad she is on my team.

Dr.Onofrei has been amazing through my complicated journey. From a hard beginning with devastating Long Covid and continuing to coordinate the care I was in so much need of.
