This was my first appointment with Dr. Wong. He went through a lot of issues with me that other doctors had not and so I have a lot of respect for him just for that one visit and I’m happy to be a patient from memorial care again I moved from Long Beach to Huntington Beach and I was very happy to meet Dr. Wong and his staff because he had information that a different doctor had never went over anything with me and Dr. Wong found something that the other doctor didn’t tell me about so I am 100% with him with memorial care and with his office staff and that’s why I gave him a 10 thank youOk

Dr Wang always takes my concerns seriously. Most healthcare professionals don’t seem to, and I always appreciate my appointments with him.
