I feel so very blessed that Dr. Taylor-Cousar is my doctor! In addition to being extremely smart and current with research information, she also cares about me and knows personal things about me (my husband's name, my dog, etc.). I have total confidence in the care I receive from her and appreciate her so much!

National Jewish Health PatientJanuary, 2021
Dr. Taylor-Cousar is simply THE BEST. She is brilliant, kind, and genuine. She bases her care on the evidence but still gives patients the autonomy to make decisions that fit best for them. Although I know she has many patients, research projects, advocacy efforts, and more going on at any one time, she always makes me feel like I'm the only thing on her mind. She is so present and attuned, a true gift!

National Jewish Health PatientJanuary, 2021
Dr. Taylor-Cousar is wonderful. I feel seen and heard. I feel like she's doing the best she can to help me, and she is very nice and informative.

National Jewish Health PatientDecember, 2020
