Jun-2023
Dr Guan is the first dr to ever HEAR what I was saying. He listened to me with both ears! I feel safe and respected when walks into the room. He addresses my concerns and he takes the time to find the best way we (I, Him) can solve the issue. He explained everything to me not only in words but he drew pictures to help me understand what he was saying. I myself as his patient trust and respect him not only as a doctor as a person, a gentleman. Dr Guan has always made me feel important, I mattered as a person, not just a patient.
His Integrity stands strong.
Thank you
