Can I buy stock in Trader Joe's?

Excuse me, I'm wondering if you could shed some light on something for me. I've been a loyal customer of Trader Joe's for years now, and I've always been impressed with their products and business model. Recently, I've been thinking about investing in the stock market, and I was wondering if it's possible to buy stock in Trader Joe's. Is there a way to invest in this company, or is it a privately held entity that doesn't offer shares to the public? I'd appreciate any insight you could provide on this matter. Thank you.
