I live in Pacific Northwest and this tree is in our backyard
Here is the photo of its leaves
Do you know what tree is it?
It doesn't look that nice. It's not evergreen and quite trashy in the winter.
It appears to be a Madrone (https://en.wikipedia.org/wiki/Arbutus_menziesii); it is loved or despised in equal amounts, some would consider you are fortunate to have a mature specimen. Certainly a distinctive tree, see if the description of the Madrone coincides with your tree.
