The word Lungy grosses me out. Something visceral. I imagine viewing a human organ or the chest being opened. Sorry, but I thought it might help you. If people agree, say something below. If not, I am an oddity and can be ignored.
Yep, it does seem some people don't like the name, which I do understand. I wanted to add a slight lightness to something medical-sounding, I guess trying to make healthcare less intimidating - I'm sorry it has those connotations for you!
The anatomical term "pia" can be pronounced as if it starts with either "pea" or "pie". Writing "pi-a" is very strongly suggestive of a pronunciation like the Greek letter pi (i.e., like "pie", not "pea"), especially as the website's favicon is the letter pi. However, the website says it's pronounced "pea-uh".
So I would think that the hyphen would bias people towards the "wrong" pronunciation.
