I [PHI] have seen and continue to see many doctors. *Dr. Fernandez is hands down the very best. He has saved my life and enhanced the quality of the life I have left.

Dr Fernandez is an excellent clinician.

Dr Fernández Pérez took time to listen to my concerns as well as time to explain results from my tests and what he further recommended.

National Jewish Health PatientSeptember, 2018
Again, the doctor was very nice--but I don't know why I have these symptoms!

National Jewish Health PatientAugust, 2018
Non-judgmental, firm, yet warm, kind, professional, explains very well. Did not spend time on computer, total "face-time."

National Jewish Health PatientJuly, 2018
Dr. Fernandez is an expert in his field, I felt blessed to have had the opportunity to be his patient. He listened, answered all of my questions/concerns, and collaborated beautifully with my other doctors in order to provide me with the best possible care. I am indebted to Dr. Fernandez, all doctors should strive to have his empathy, knowledge and genuine smile!!!

National Jewish Health PatientJuly, 2018

I have already recommended.

National Jewish Health PatientJune, 2018
I was seen over 4 days. By the 4th day I was so tired I couldn't process so much new info so quickly. I was so happily surprised I was turning cartwheels inside. I am very thankful that [my doctor] reached out and spoke to my local [specialist] to set up new therapies, and meds! It's taken 3 weeks but I finally started.

National Jewish Health PatientJune, 2018
Dr. Fernandez is the best doctor I've ever encountered. I went to [other specialists at home and] no one could diagnose my problem. I was blessed to learn about National Jewish Health and even more blessed to have Dr. Fernandez is my doctor.
