A tall specimen of a Viburnum cultivar.

Thank you for the feedback! Not having the plant in person, I don’t know the reason its lack of bloom. Sorry for the confusion, these above links are only meant to show their leaf shapes that look similar to those from your friend’s specimen. I’m not saying this is the ID cultivar. Can your friend provides us photos of the whole plant? Also closeups of leaf buds and base of the main trunk?
My guesses are based the opposite lobed leaves. I could be wrong but still leaning to Viburnum group. Without flowers & fruits to identify its genus, the mentioned details would help us narrow down for your friend. Thank you and best wishes!
Check out the included link below images of a Viburnum with similar leaves and branches (again, this isn’t an ID ). Beat wishes!

My friend said this is not her shrub. She said her shrub does not change color, nor does it flower. She said it grows straight up versus spreading out. These leaves are dark green vs. chartreuse. Any more ideas? I appreciate your time and investigation!

Oakleaf hydrangea.

Another Viburnum with similar looking leaves shapes. A cultivar of V. opulus ‘Park Harvest’.

Without flowers to help with the ID. I could only guess this could be either a type of Viburnums, possible the American cranberry bush Viburnum trilobum(?) or a cultivar of oakleaf hydrangea (Hydrangea quercifolia)? The closeup of the leaf buds would help more. Although I’m leaning toward Viburnum, flowers are needed for a confirm ID. For now checkout these included link for information of both genera. Best wishes!
