National Jewish Health PatientJanuary, 2019
I was very pleased with Dr. Otsu, I know it is difficult to evaluate new patients. She was very thorough in her examination and her recommendations regarding my prescriptions. As well as her explanation regarding my health and health concerns.

National Jewish Health PatientDecember, 2018
Would have liked more time with Dr. Ostu. [Unrelated] I felt Dr. Otsu was far more experienced and my time with her was brief.

National Jewish Health PatientJune, 2018
Completely failed to pay attention. Told her we were tapering down [condition] meds per dr. instructions - record says stopped giving meds. Leads to concerns of poor future care. Inattentive & sloppy.

National Jewish Health PatientMay, 2018
we saw many doctors during our trip this particular doctor I would never consult with again. she was scattered and at my final visit she left us completely hanging. my wife and I were just in shock we didn't know what to say. thank god we saw other doctors that gave us explanations support and advice as to what to do next

National Jewish Health PatientMay, 2018
This provider 1st sent her coordinator to explain and then she came and fully explained to me again.

National Jewish Health PatientApril, 2018
I've felt more relaxed after seeing the National Jewish Health providers, [condition]. Much more defined and my primary care provider is now able to understand why I had continuous flare-ups.

National Jewish Health PatientJanuary, 2018
I would recommend NJH and OTSU if asked but no one will ask.

National Jewish Health PatientDecember, 2017
My husband and I feel like she is being very by not talking to my husband when we're there. my husband knows a lot because I had time remembering certain things so my husband would answer and she would not even acknowledge him.
