“Brooke is just wonderful. First of all she has kindness, which is rare in our days to see. People are usually occupied trying to make money and just doing their jobs briefly. She's very attentive and very compassionate, which is quite important with what she's doing helping disabled people. She is very professional. Whatever questions we had, she would definitely put her time even if it was extra time to find - I mean outside of out visit, she found the time to give us specific information that my brother needs. So she's fabulous. Five stars is not enough, I would give her 55. I wish more specialists were like her. ”
