Is there a way to verify if someone really is a physician?

I've been dating a guy for 9 months that claims he's a resident physician in California.

For some reason, my intuition is telling me something is off. He texts me frequently throughout the day and sees me 4 nights a week (i know resident physicians are extremely busy and most are lucky to meet up or go on dates a few times a month). As well as finding an old dating profile he created a few years ago that said he worked in finance.

Is there some website I can go into, type in his name and verify credentials? I can't believe I'm asking this but something just seems so off and I'd really like to verify.
