I thought the staff and Dr. Ji himself were completely professional, efficient and friendly. "Lisa" rescheduled my original appt. and set up today's after Dr. Yang was not available. She told me in advance what to expect on my first (teledoc?) video doctor consultation, I was reminded this morning and talked to Dr. Ji this afternoon. He was very congenial and knowledgeable and answered all my questions. Good job, all around, in these difficult times.

I was very nervous about finding a new doctor after moving from AZ to CA. However Dr Kosar made me feel very comfortable and he seemed very knowledgeable

This is the first telehealth connection with Dr. Ostrom. It went really well. I was able to answer Dr. Ostrom's questions. A face-to-face interaction was not necessary with this appointment at this time. By not going to the office (to avoid exposure to COVID-19), it's a good way to 'see' the doctor in the safety of my home.
