"This clinic has been an absolute nightmare for me. They are incompetent and dangerous. ... Their billing/coders are also incompetent. They are trying to get me to pay a $1600 bill that shouldn't even exist."
— PissedConsumer review"Consistently listens to my concerns with attention. I never feel like I'm being rushed out. Thorough explanations of labs. My provider... pays enough attention that she can tell if I'm leaving something out and gently encourages me to be completely open..."
