with Lin's last comment about humidity. You moved from a more humid place in PA to a much higher, drier place in CO. High altitude enhances dryness in the air - the air is simply less dense. (we lived in Utah for 20 years before moving here, and our kids still live there, a very similar climate to Colorado)
So, sitting it on a tray with pebbles that you keep full of water (the water not touching the bottom of the pot) will very likely help your plant, too. A little extra humidity is good for people as well, btw.
But first, yes, I would look at the roots and re-pot if you see lots of roots going round and round in the pot when you slip it out. IF you haven't been giving it any fertilizer, it might need some of that, too. But IF you do re-pot, check the potting soil bag, because sometimes it has fertilizer already added. That will be enough for your plant going forward for probably 6 months.
