National Jewish Health PatientJuly, 2020
I am so thankful I have Dr. Otsu helping me. Her ability to diagnose and test what has been happening to me has really improved my life.

National Jewish Health PatientMay, 2020
She seemed rushed during this visit. She didn't have much additional to offer but then again there's not much more to offer with my condition.

National Jewish Health PatientMay, 2020
Explain in great details.

National Jewish Health PatientApril, 2020

National Jewish Health PatientFebruary, 2020
*Dr. Otsu is fast & accurate, makes certain that all possible testing is done & because of this has helped me far more than [other providers].

National Jewish Health PatientFebruary, 2020
Good experience and willing to work through several methods of care to determine which works best.

National Jewish Health PatientDecember, 2019
I will not see her again. I found her to be very unhelpful.

National Jewish Health PatientOctober, 2019
Rude, uninterested, never examined me. Walked in, folded arms, leaned against the wall as far is she could get.
