I have known Dr. Hsia since he was a fellow at UCSF. A day after the Friday installation of a pump/shunt for my glaucoma, I experienced pain and headache. Dr. Hsia met me in the deserted clinic at 7:30 pm and stayed with us untilShow more he relieved the pressure causing my pain. As a result of his dedication, I have followed him to his clinical and academic positions into private practice. I travel from Reno to Walnut Creek to see him and he continues to have the same calm dedication to his patients.
