Great and caring doctor. Happy to have him as one of my medical care giver.

I have met Dr Fleishhaker only 2 times. Office visits are performed by PA and other professionals but not the doctor. I have seen his associate Michelle on several visits but today another associate inquired about my progress since the epidural. I believe that it is important that I meet consistently with Michelle and I explained that. I have had significant improvement with the 2 epidurals, one in September and 2nd in November.

The Best and only place to go for your pain management procedures. Dr Flesichhacker is the Best to see when you have pain, your and quality of life is not what is was, because of the horrible pain, that for me makes cry out and brings me to my knees. But Dr Flesichhacker knows exactly which procedure to do after speaking with you. I know what when I go for a procedure, that is rights on point to where he does the epidurals the nerve blocks , etc. I feel like a mensch , a human being again. I could do things again, the pain at minimum Dr Flesichhacker is compassionate, professional, friendly, he kind and patient. He put you at ease, He explains to you what is going on, and what he feels would be the right procedure to do, to give you a better quality of life, when you are pain free. I recommend Dr Flesichhacker and Union Anesthesia Associates highly to all.
