"During my annual visit with Dr. Sadhu, I was incorrectly charged a copay for what should have been a fully covered preventive visit. This is now the second time I’ve encountered billing issues here... I urge everyone to carefully review their bills."
— Birdeye - Prima Medicine South Riding patient review"I used to really enjoy this practice. I felt like I was getting genuine care. In the last year or so it has just become a constant money grab... The doctor will be in and out without asking any questions... just feels like I'm a quick Buck to them."
— Birdeye - Northern Virginia Family Medicine patient review"I would give them zero stars if I could... They clearly have no clue what they are doing at this place. We are convinced that one of their doctors treats you based on WebMD — he looks at the computer the entire time you are in the office."
