    We found her friendly and professional. She explained each step of my cognitive assessment and summarized the results in plain English. And she recommended a 6-month follow-up.

    Dr Nielsen is very great at what she does. She has seen me many times and I always feel she is trying to get to the root of my issue. She doesnt 'sugar coat anything. And shares with my wife everything. I totally appreciate that with all the HIPPA out there. She just wants to get to the bottom of whatever my issue is. She could not be more awesome, Will see her in 2 months for follow up.
