    I enjoy working with Dr DeLange. He listens attentively and truly cares about current issues. His explanations are clear and he always asks to input on treatment options. He always ends each appointment with what else can I do to help? I feel validated and listened to by the end of appointment.

    Dr DeLange is a very knowledgeable, thorough, all around amazing doctor.Listens to all questions and concerns, takes the time to establish diagnoses and provide varied suggestions. He makes your visit feels like a 2-way conversation and that he has your best treatments in mind. Not just dictating upon high and trying to rush you out the door. Best Nuero I've ever had in almost 30 yrs. Never let him go!

    I appreciate that Dr. DeLange takes time to listen and I do feel "heard" during my appointments. I wouldn't mind hearing more comments or receiving education from him regarding my diagnosis or my home / self-care activities. That's not a criticism, just a desire, although I realize that time for each appointment is limited.
