I'm wondering if anybody out there has come across a way to send notifications from an android phone to my roku TV screen. Thank you for any input available.
No.

Assuming you have your Android phone constantly mirrored (Miracast screen mirroring) to your Roku, then you would see them.
Rokus arent Android devices, so there no inherent system-level connectivity or integration (which is what would be required to show notifications at any/all times without interrupting current viewing/usage).
You can always suggest such a feature, but chances of it ever happening are probably right around 0%.
