After 30 minutes I got to see Dr. Grewal. I had some lab tests and we throughly discussed my issues. She was very comprehensive, even told me I'd been taking one of my pills wrong. She ordered follow up test and scheduled another appointment. It was obvious that she is a smart lady.

Very condescending and uncaring. No empathy for her patients who have difficult chronic illnesses. I saw her a handful of times and will not be back.
