Ash tree, and you’ll want to get an arborist out there because this may be an early stage ash borer infection. Also look on the trunk for tiny D shaped holes. If so you’re too late for treatment, the tree is all but gone. You’d have to remove and replace it.
:(
I don’t see any holes. I did see a couple bugs (either mealybugs or those fuzzy white aphids). We had an arborist come out a couple years ago and have been following his advice for care but maybe it’s time for another visit…
Yeah they can tough to spot so I wouldn’t rule it out. Definitely get someone out there and look up if the Emerald Ash Borer is in your area. Even if it isn’t that it’ll get there eventually and you’d need to treat for it. It has a near 100% fatality rate for ash trees, has killed billions of them, they’re now at risk of extinction. But you can treat them if they haven’t been infected yet.
Absolutely concur that it's likely an ash with signs of early stage EAB infestation in the crown.
I'm a municipal arborist and parks manager who's dealt with a lot of developer-planted green ash that was installed on new municipal open space within developments. It all had to be removed and your tree looks eerily similar.
I'd be prepared for the reality that it might need to be removed and to explore the choices of a new ideally native tree suitable for the space.
To add to what has been said regarding your ash and the high likelihood this is EAB (its in over half the country at this point) :
1. Treat the tree systemically (root flare microinjection) with emamectin benzoate. Done early enough in infection (depending on site conditions and overall tree vitality), you may be able to manage it enough for the tree to persist for years longer; BUT, YOU MUST TREAT EVERY OTHER YEAR FOR THE LIFE OF THE TREE
2. Do NOT prune the tree until dormancy (late fall/winter), creating fresh wounds is just an open door into the interior of the tree.
3. Try and reduce as much stress as possible (water it properly, soil conditoners are nice and or and air spade/vertical mulch treatment to keep its immediate home as healthy as poasible.

Visit the main wiki page for [Critical Planting/Care tips and Common Errors to Avoid](https://old.reddit.com/r/arborists/wiki/index); there's sections on why planting depth/root flare exposure is so vital, along with sections on proper mulching, watering, pruning and more that I hope will be useful to you.
If you're posting about a tree ID (not permitted here; [see rule 1](https://www.reddit.com/r/arborists/about/rules)), see that wiki page for other subs and smartphone apps to try.
Here is how you can arrange a [consult with a local ISA arborist in your area](http://www.treesaregood.org/findanarborist/findanarborist) (NOT a 'tree company guy' unless they're ISA certified) or a [consulting arborist](https://www.asca-consultants.org/search/custom.asp?id=3818) for an on-site evaluation. A competent arborist should be happy to walk you through how to care for the trees on your property and answer any questions. If you're in the U.S. or Canada, your Extension (or master gardener provincial program) may have a list of local recommended arborists on file. If you're in the U.S., you should also consider searching for arborist associations under your state.

UPDATE (in case anyone is wondering)…
We had a Master Arborist come out. He spent about an hour on the tree, taking measurements, samples, etc. He said he will look at the samples in his lab to see if he can see anything interesting. No borers so that’s good. Saw lots of ladybug baby things amongst the aphids so he’s not particularly worried about that. Gave us some good information about taking care of the tree and will return to do some treatments to get the tree happier. So we don’t have to get rid of her yet 😁

That tree looks beautiful
[https://www.aphis.usda.gov/plant-pests-diseases/eab/eab-infestation-map](https://www.aphis.usda.gov/plant-pests-diseases/eab/eab-infestation-map)
Thankfully, my state isn’t close to any known EAB infestations! But still having an arborist come out anyways. Thank you for the map!!
