Is there a way to have an Awake() run every time a scene is loaded.

I am programming a game where the camera will adjust to fit the screen, the only problem is that there is a way to switch between screens to reach a certain menu. The only problem is that once you go to the menu and select to go back to game the camera will not adjust again. Am I making this harder than it needs to be (Like instead of several scenes have on, I don't see how this will work but maybe) or am I just unaware of a way to work this? Thanks for any help!
