I went to emergency with extreme stomach pain.  I was sweating like crazy.  Dr Oholleran said it was in my head.  He rubbed my head and told me to go home.  He said it was my imagination.

The pain stopped, but began again about a month later.  I went to emergency and Dr Oholleran was there.  He said not again,  "what's the matter, are you not getting enough attention?  You don't think you are pretty?"  He told me to go home.

I went a third time to emergency about a month later, and he yelled at me.  "What are you doing here?  I told you not to come back."  He is very sexist.  He said "that's why medical costs are so high.  Women just need attention." He really yelled at me and said he never wanted to see me there again.

I went to emergency a few weeks later because again I had such intense stomach pain.  It was a different doctor and he did an ultrasound.  I had lymphoma.  

Dr Ohalleron waited so my cancer went from stage 1 to stage 2.  Dr Ohalleron insisted it was my appendix was inflamed and went to remove it.  Instead he took out a healthy appendix after he saw tumor's the size of a grapefruit on my left side and 9 walnuts on my right.  

Even the oncologist yelled at me, because he said you had to have felt it.  I hate doctors.

OHalleron is not only incompetent, he's a bully, an idiot, not very nice, and definitely sexist.
DO NOT SEE HIM
