I am pleased with my physician

National Jewish Health PatientNovember, 2016
My case is a little complicated and it requires attention to detail. *Dr. Mccarl tries.

National Jewish Health PatientAugust, 2016
receives an A for the short time I saw him , I had a list for us to solve. My current symptoms and a full work up to r/o allergies/asthma/ etc. now Iam still not perfect, but he resolved my initial concerns for my visit. I would have more goals , but Iam moving out to Kaiser to resolve thosepayer change.

I could not ask for a better team of doctors and their support staffthe techs also are super in doing what they do to do the tests and labs etc

National Jewish Health PatientAugust, 2016
*Dr. McCarl is fantastic. He works to assure that even when I reach the donut hole for Rx he gives wonderful suggestions.

I used to work in Medical Ophthalmics. lasers and optics, and have a good idea of how plugged in a Doctor is with their patients. Dr McCarl is one in 100!!! On reading his summary of my initial visit, his medical and personal summary was lengthy and indicating his personal interest with his patients. Also his speculations regarding a possible involvement of "PHI" may prove true during my next scheduled examination. If there is a way to rid me of the ongoing difficulties, even though I'm not a typical patient profile for National Jewish, I'm confident this may be diagnosed and brought to an end with Dr. McCarl help.

National Jewish Health PatientAugust, 2016
always good

National Jewish Health PatientAugust, 2016
I would highly recommend Dr. McCarl to anyone needing a pulmonary diagnosis/treatment.

National Jewish Health PatientJuly, 2016
I asked a lot of questions so I am not sure she would have explained so much without my questions.

National Jewish Health PatientMay, 2016
I feel the doctors there are really good but the staff on the other hand has a little things I need to work on
