It's an absolute business necessity in any industry. Your headshot is part of your personal branding, and people expect to see it everywhere – on business cards, your website, public benches and even billboards! Your business is a face-to-face relationship and potential clients want to see yours.
TIP: Update your photo every few years. It is important to keep your headshot current, especially now that so many people begin their search on the internet. You want your online prospects to recognize you when you finally meet them.
