Dr. Haak was very efficient and structured. He kept the appointment moving forward yet was incredibly compassionate and deep listening. I was very happy with how the appointment was handled from start to finish.
- 4 out of 5 starsReviewed on 2/19/2026
I was assigned to this provider as a result of my original provider separating from Geisinger. It just seems to me that this provider Is not sure how to proceed or perhaps doesn't have a vested Interest In my ongoing care. I have had the same symptoms and have tried several medications to remedy them. At this point I have grown frustrated and exhausted with this treatment.
