Wow...Where do I start! Doctor Haller is the greatest.I was treated like family how many doctors give you there personal number to call if you are having any problems big or small, before I went into surgery I was introduced to this whole staff and what there jobs would be in the operating room. Let me stop, because I can go on and on. Yes...If you need surgery I would recommend anyone to go and see Dr. Haller. Oh...I forgot...after my first visit I was hooked. Thank you Ms receptionist for making feel at home, and thank you Dr Haller so very much.
