I want to file a malpractice suit against my father's doctor and the hospital he was in.

To be as concise as possible, my father's memory was in question, in midst of confirming 1st stage dementia . He was seen at Dr office on a Wed, the following sat he collapsed and went to ER by ambulance. When he arrived his foot and part of leg was cadaver, I do not understand, nor will I get returned calls why his foot was overlooked.. While at hospital he was not scanned for 24 hours. I was then they found a ruptured ulcer and had an answer to low blood pressure and septic. There is much to this story and I am looking for an attorney in Alaska that handles malpractice suits.
