They were wonderful

National Jewish Health PatientApril, 2021
Dr. Covar went above and beyond with [my son's] case! she has always been great at communicating and also explaining in detail the plan of care and the complexity of his case. she also values my opinions and has his best interest at heart!

National Jewish Health PatientMarch, 2021
Dr. Covar is an expert in her field and she is a very kind, caring and compassionate person. Because of these factors and because she knows and understands [my son's] history so well, we asked her if he could please remain as her patient when he began college. That has worked out well, and Dr. Covar has been very accommodating about seeing him on his breaks from school here in Denver.
