Here's the nightmare that keeps injecting-practice owners up at night: your best injector, the one half your patients book specifically to see, gives notice, then opens or joins a competitor across the street, taking a chunk of your patient base with them. In aesthetics, patients frequently follow the injector, not the practice, which makes this threat unusually real. And the protection most owners assume they have, a non-compete in the employment agreement, is precisely the protection that has become least reliable, as non-competes face increasing scrutiny and restriction nationwide. If your retention strategy is a non-compete you've never tested, you may have less protection than you think.
This is general education for owners, not legal advice. Non-compete and non-solicit enforceability is highly state-specific and legally in flux; consult employment counsel.
