(CASH PATIENT). Thank you!!!"

"Dr. Wang is the best Primary care provider I've ever had. He is very detailed and listens to his patients thoroughly. His office is open late and the wait is not bad at all. You can come in here for anything from Bronchitis to a complete physical."

"I rushed my dad into urgent care today, he was so nervous because he had not gone to doctor in 10 years! The ladies at the front desk were so kind, they were able to calm his nerves. The doctor took my dad right away and took very good care of him. Celina even translated for him (my dad is only Spanish speaking)! This will definitely be our go to doctor now."

I appreciate the fact that we're never waiting long to see the doctor AND the fact that the doctor takes his time to address all our issues and answer all of our questions. I never feel rushed. The office is always clean and also open 7 days a week, which makes it very convenient for visits."

"This is a second location for Dr Wang. He is a wonderful Doctor. The thing I like about this Dr is that he spends time with the patients and not rush them.
