worst experience

He was covering for my regular dr while I was in the hospital. He examined me for one minute then marched out and changed her orders WITHOUT TELLING ME. I had to threaten legal action while sick in a hospital bed. Horrific experience and without a doubt the worst dr I have seen.

This doctor was my Internist when I had an HMO. To this day I cannot believe what happened. I visited him because I had what I believed to be a "pinched nerve" in my lower back. After waiting 20 minutes, Dr. Willen examined me. After identifying the region of my pain, he actually made a fist and hit me hard with his knuckle in the area of the pain. He laughed and said... "Is that around where it hurts?". I said, "What are you doing?". He proceeded to say he was only checking to clarify where I was feeling pain. Needlesstosay, I never visited this doctor again.
