Very impressed with Dr. Onofrei's compassion and understanding of what I was experiencing.

National Jewish Health PatientJune, 2023
I was concerned that my first visit would be time consuming and that the provider would recommend significant changes in the plan of care developed by my provider in another sate.. My worries were needless. The focus was on making my transition to Colorado smooth and supporting me in continuing with the current plan.
