    Dr. Liu was thorough, realistic, kind, and understanding. I trusted his knowledge. He was able to confidently answer questions with a known answer and acknowledge unknowns. He thoroughly explained follow up (him vs. [staff]) and expectations moving forward. He was realistic in weighing pros and cons in life. He spent time in answering two of my questions that weren't directly related to this visit (but still related to ophthalmology), which I appreciated.
