The overall experience at Premier Heart and Vascular Center is quite good, considering the mixed feedback from patients. The facility appears to have a caring and knowledgeable cardiologist in Dr. Huy Khuu, who has saved a patient's life and is appreciated by many. The center has a convenient location, modern amenities, and is wheelchair accessible. However, one patient reported a significant issue with the billing office, which incorrectly billed them for a procedure and took a year to resolve. It seems the billing department needs to improve its accuracy and communication with patients. Despite this, the practice has many happy patients who praise Dr. Khuu's care and the office staff's friendliness. It's worth noting that the billing office's mistakes seem to be a recurring issue, and patients should be vigilant in checking their bills and communicating with the office if they spot any errors. Overall, Premier Heart and Vascular Center has a lot to offer, but its billing department needs to step up its game to match the high standards of Dr. Khuu's care.
