I feel like Dr. Chamberlain listens to me when I talk with her and she seems to remember my chart from year to year whereas other providers I’ve gone to, I noticed that they don’t remember some of the things they told me in the past or it seems like they’re just reading your chart for the first time five minutes prior to your appt. I also feel that Dr. Chamberlain is very knowledgeable in her field and cares about her patients. She takes the time to ask how they’re doing, and I’ve never felt rushed in my appointments with her.
