Winter burn and dying shrubs -- please help!

After the winter from hell, our formerly large and healthy yew is turning brown. There's still some green left and a little growth, but I'm afraid it's dying. Is there anything I can do to revive it? Should I contact a professional? Any ideas or recommendations would be greatly appreciated! 

Our whole front hedge are yews and one is almost dead; it's been dying for a couple of years and I think the last couple of winters have finished it off.  We are talking to an arborist now about replacing it with two smaller ones.  But the other yews in the hedge also have some bits of brown here and there that are worrying me.

I was shocked at how quickly my yew deteriorated. It was perfectly healthy and full last year. It's very sad, plus I'm also worried about the replacement cost. 

I have a huge (and one year new to us) laurel that got absolutely fried.   Couldn't find the spray during late Autumn, chanced it, and it's probably gone.

I have a few azeleas that turned dry brown during this winter, including one really large one

Same thing happened to my acuba.  Fortunately the interior growth is fine.  I am in the process of cutting back all the brown and dying parts, giving up much of the buds in the process, and that seems to be working.  Yews grow a lot more slowly than acuba though.  If you have enough healthy growth on the plant, you could try cutting back the dead/dying and hope this will will stimulate enough new growth to keep the plant going.  Alternative is to replace it.

My hollies look terrible.  I am leaving them alone for now and keeping my fingers crossed that they are not completely dead

@PetuniaBird, my hollies are also in bad shape. I found this on line. I'm going to feed mine posthaste.
