  • Dr. Yeh was incredibly kind. She went so much out of her way to get me in. And for the first time in about a year and a half, I felt like a provider actually listened to me and met the degree of clinical care, both objective and subjective, you know, bedside manner. But like her clinical experience is phenomenal. I could not recommend her more. I was so, I mean, I think she's changed my life. And I think it's really important to note because that is a woman who is both brilliant and really still has her curiosity in medicine, which is as a clinician myself, rare. She cares and she makes a difference [redacted]
