If you don't know anything about me and I suppose there are A LOT of people who don't, since I would be a lot busier if people knew I existed and the quality of my craft. I am a huge snob when it comes to espresso...
It's up to you as a business, or someone looking to hire a photographer. I'm not one to call myself a professional, I do let me clients use words like that to describe me to their friends or referrals.
