Dr. Ewing Haas saved my life from first noticing about a brain tumor, therefore she gets a 10/10. the only complaint is she was booked out for 2 months for an appointment

The staff has always been very friendly, informative and helpful.Dr. Ewing Haase always spends plenty of time explaining things and I never feel rushed with her. Even when I have way to many questions.Her bed side manner is ver professional, kind, and caring. I appreciate this. Being human is more important to me than having a perfect medical outcome at all times.

Dr Ewing Haas, Chelsea and Laura are all excellent in what they do. I am so very happy that I switched from ProHealth Care last year!!
Nov. 13, 2019
She is very understanding, is never judgmental, and listens to all my concerns. I have recommended her before, and will continue to.
Nov. 13, 2019
I was not asked if I would be okay having a Male intern perform any part of my exam. I felt like I had no option but to endure the exam. I honestly don't know if I will ever come back.
Nov. 13, 2019
Dr. Ewing Haas knows I am opposed to counseling for my anxiety issues. She recommended Silver Cloud as a way for me to work through some of those issues without having to see a therapist. Dr. Ewing Haas goes above and beyond what's expected to provide care that is perfectly suited for my needs. She knows my history so well that it feels like I'm her only patient. Love her!

Sept. 12, 2019
I have a very good Doctor, am very pleased with my care and the staff is always courteous. On a side note, the lab people are great at drawing blood, I've had some really bad ones in the past but not at Froedert.

I love DR Ewing-Haas I tried to coax her into moving to the new Waukesha branch, but she wasn't having it. So I will still see her where she is at. She is very friendly and personal.
