Can I get euro coins in the US?

Excuse me, I was wondering if it's possible to acquire euro coins while I'm in the United States. I'm planning a trip to Europe soon and I thought it would be convenient to have some local currency on hand before I depart. Could you please shed some light on whether this is feasible, and if so, where I might be able to obtain them? I'd really appreciate any advice or information you can provide. Thank you.
