    I don't think I have ever been this confident or cared for a provider like I do with Diane Thompson. She is knowledgeable, very caring and "down to earth." I am at ease and trust her with my care. It is very important for a patient to feel this way about the care they receive.
    she was nice informative made things easy to comprehend and gave a good treatment plan. I am breastfeeding but having a lot of physical pain throughout my whole body that affects the quality of my life. I have been taking tramadol a day because a lactation specialist said it was okay and haven't seen a change in my daughters behavior sleep or health. Diana Thompson said she doesn't prescribe medicine to nursing mothers which I can understand but I have done the reasearch and spoken to specialist who ok'd it but she wouldn't give me anything to manage my pain. I asked for physical therapy which she agreed to and blood test to rule out anrbinf else. I already suffer from two diseases adenomyosis and endometriosis. she was absolutely excellent she listened understood and is willing to look into what else could be wrong and didn't shrug me off like other doctors she made me feel like she cared so I'm grateful and will want to see her normally. just hope she is willing to give something that can manage my pain so I can have a better quality of life.
    I have had one of the best experiences at this practice, have been bragging about it since then.
