Nothing. Everyone is always great! The nurse went out of her way to help calm my son down to stand on the scale. Dr Dyess is always kind and supportive, helping me make informed decisions about my son's care

I did not see much of curiosity and thoughtful conversation with the doctor about my child's problem.

Listen and actually make a positive change to the plan to keep her numbers better at school. Her numbers are terrible at school and dr. Dyess did nothing to fix it. They wasted my time having me sit there for over 2 hours & I had to come back for blood work
