We have a lot of douglas firs on our property, and the lawn is in three pools of green of various sizes, where the trees are not. They do border them, though, and we have to sweeten the soil every year to counterbalance the acidity of the firs - we use SuperSweet...
I would try getting a soil testing kit and seeing what your soil it like where you want to grow the grass, then you can look into what is needed to correct the ph for it to grow. You might do better to only have the sunniest, least tree-ish part be grass and put a boundary of a hardier groundcover around it for a larger area to be green. There aren't many things that will grow underneath firs, I can say that! I've had some success with acid-loving plants that don't mind some shade, like rhodies, azaleas, andromeda and blueberries.
Ajuga is a decent groundcover that can handle some acidity too (and you don't have to mow it). Where I am we also have Oregon Grape (it's a bit like a holly, rather than a grape) that grows just fine under them but it is larger and spiny to boot.
Good luck!
