In patients' words

"He is one of the few great doctors in the AV I've found. He is easy to talk to and I never feel like he's rushing me out or treating me like every other patient, but takes the time to listen to my conditions and makes a care plan just for me."

RateMDs (Dr. Jatinder Pruthi)

"I’ve been seeing DR Wong for 2 years now and he’s been an excellent gastrologist to me. Because of him I’ve have not been in the hospital dying like the years prior to having him as my doctor."

Vitals (Dr. Edward Wong)

"This place is a joke. Made me wait a month and a half for an appointment then called same day to cancel? Then they laughed at me because acted like they sent a confirmation which they never did so I called out their lies."

WebMD (Dr. Edward Wong)

"DO NOT waste your time with this man, he's a poser."

Vitals (Dr. Sethu Madhavan)
