Adenium species aka desert flower.

I'm thinking it is one of the Pachypodiums.

with Karen it is more like a pachypodium since there are thorns. Adeniums do no have thorns.

Both Adeniums and Pachypodiums are caudiciforms, so it is also being grown for its caudex. Hope you get to see the blooms on your plant later on! Really grows best outdoors with all the sun it can take. And both plants likes to be treated like tropicals, getting watered daily when temps are really warm to hot (90F to 100F ++). Just make sure the media is very well draining. I love these plants, they truly survive our triple digit temps when it comes.

I didn't even notice the thorns, just paid attention to the leaves and the overall plant.

Looks like Pachypodium saundersii. From southern Africa, white flowers. But not the form I'm used to seeing. The difference between saundersii and lealii has a lot to do with the main stem dying back on saundersii, which I am seeing here, or else somebody pruned discreetly. But saundersii is typically a wide-bodied plant, basically a blob. Maybe it's growing in lower light, or maybe it will get wider with age. Examples of young and old plants here...
