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

Best Internist Multi-specialistI have followed Dr.Wang through the last almost 20 years and now at Memorial Care , Fountain Valley. It has been a lot of years since my daughter was in elementary school and now she’s in college. He’s been my doctor. His has multiple specialties besides being internist. Dr Wang is knowlededgeable and very efficient. He is excellent at what he does and I trust him with my life and that doesn’t come easy when you have multiple chronic conditions. I’m very grateful that he’s been my Dr internist multi specialist and I’ve I’ve been very blessed to have him as my primary doctor under Medicare and I am just I don’t want him to ever retire. He’s he’s the best and I got referred to him from a neighbor in Huntington Beach. I now live in Long Beach, but I will still go to Fountain Valley for my doctor. He’s that good.

He was very thorough and requested some new labs that were very helpful. His bedside manner was appropriate and he was open to my questions. I am in the medical field and I know a good doctor when I meet one. Highly recommend him as an internist and primary physician. Memorial care as a whole has been also helpful in navigating my health and appointments to specialists.

I have been a patient for Dr John Wang in Fountain Valley, CA for close to 20 years and have followed him though several office changes over this time. However, since he has joined Memorial Health Care all things have gone for the worst...You now can't call his office directly and you have to go through the terrible Memorial Care screening system first. Yesterday that took me 3 hours of wasted time where I never even got the doctor's office on the phone.I am covered by Medicare plus I have a costly PPO supplement policy and I never requested to be with Memorial Care so I definitely don't want to be treated like I am with an HMO. Very frightening!!Last week due to communication problems between the doctors offices within the Memorial Care system, I almost missed a needed medical procedure due to their negligence... If that wasn't bad enough those I spoke to within Memorial Care didn't even care as if I was wasting their personal time which is horrific!!!

I have been a patient for Dr John Wang in Fountain Valley, CA for close to 20 years and have followed him though several office changes over this time. However, since he has joined Memorial Health Care all things have gone for the worst...You now can't call his office directly and you have to go through the terrible Memorial Care screening system first. Yesterday that took me 3 hours of wasted time where I never even got the doctor's office on the phone.I am covered by Medicare plus I have a costly PPO supplement policy and I never requested to be with Memorial Care so I definitely don't want to be treated like I am with an HMO. Very frightening!!Last week due to communication problems between the doctors offices within the Memorial Care system, I almost missed a needed medical procedure due to their negligence... If that wasn't bad enough those I spoke to within Memorial Care didn't even care as if I was wasting their personal time which is horrific!!!Memorial Care makes you go through their Patient Navigators- I wouldn't trust them to navigate me to the Bathroom. THEY ARE THE WORST!!Due to these issues, I have requested for my complete records file so that I can bring these records to a new doctor and Dr Wang's office wouldn't get my records for me!!!!!!!!! I don't understand why they couldn't do this since that is a requirement of all doctor's to do when requested by a patient.I can only recommend for others to stay as far away as possible from Memorial Health Care or Dr John Wang unless you may want to be treated as I have been. I am on Medicare plus I have a very expensive PPO supplement

Did not seem interested in responding to my questions, kept repeating himself. Waste of my time especially when it’s concerning my health.

I have been dealing with I think is a health issue, and asked him to get test done regarding, and all what he did was to prescribed medications without taking a look at what I think is important.
