We're about 20 minutes west of Springdale. My wife grew up there. Sorry, haven't had the pleasure of meeting your dad.
Your plant appears to have Philodendron erubescens as a parent, likely a hybrid. The leaf vein structure is very similar and the red stem and petioles is a strong indication of that parent. You can read a bit more about it here:

The leaf shape is not the same but that is only natural variation and is common in Philodendron species. Variation can be caused by natural growth the same way people are variable or as a result of the influence of a different plant as one of the parents.
Erubescent means red. er⋅u⋅bes⋅cent /ˌɛrʊˈbɛsənt/, adjective becoming red or reddish; blushing.
Philodendron erubescence is commonly called the "blushing Philodendron".
It isn't uncommon for people to make up a name when they come across a variation or hybrid that is not a good match to the accepted form or known form of a species
