She's very respectful

star star star star star

Dr. Nicholson and her team seem very knowledgeable which we appreciate. They are very quick to respond online when a need arises which we appreciate as well. However, what we don't care for is how every time we go, we are treated like it's the first time we have ever been there. We get asked all the same questions about things that should already be well documented and doesn't change every 3 months. Despite the fact that my husband and I are well educated about type 1 diabetes and my son's blood sugar is very well managed, we are still left feeling like we are being talked down to. We are forced to see a dietitian or a social worker at every visit even though we don't require those services and this makes the appointments longer than needed. I'm not sure how many different ways you can tell someone that, yes, we do use whole wheat bread and eat healthy. Again, these things should be documented so we don't have to do it over and over again. It just all feels very patronizing. Overall, we are happy with the care provided but we are also frustrated by the patronizing treatment. So instead of leaving the appointments feeling happy because his A1C was great, we leave feeling drained.
