Maybe a Casetum?

It is not a Catasetum, Arthur. Looks like some kind of tri-generic hybrid. Catasetums tend to be green and do not have the kind of color formation in the sepals as does this noid which reminds me of an Odonotoglossum-Miltonia hybrid.

I agree with terrestrial man. It's some sort of Oncidium Alliance hybrid.

Although Everglades Orchids closed their doors years ago, they were kind enough to leave the photos online of the hybrids they made. It's a long shot since there are literally thousands of intergeneric hybrids, but maybe you will get lucky.

Here is a link that might be useful: Everglades Orchids

First thought was something in the Oncidiinae sub-tribe because of those striped sepals. But the petals and the lip look Casetum..ish and there are Casetums in colours other than green.
Still a maybe?

I have a NOID (lost the tag) Miltonia/Oncidium hybrid that looks like it. I think it's an intergeneric of that group.

Arthur, no, those are definitely not Catasetum bulbs, which are shaped like fat cigars. The bulbs in the photo are typical Oncidinae bulbs, like a Sharry Baby as an example.

I couldn't tell you an exact id, but whatever it is, one of the parents is almost certainly Aspasia epidendroides (Oncidium alliance).

Thank you all for responding! I had no idea there were so many noids/hybrids out there.

I'm obviously a newb and inherited a ton of orchids when we purchased this home. As for now, I think I'll look into caring for it as an oncidium.
