This is a broad question that has an endless number of answers, but NES Health recommends the following:
1. Set up your information in the Practitioner Locater
2. Market your business through social media (or any tactic you see fit!)
3. Set up a table in a high-foot-traffic area and offer free scans
4. Collaborate with other healers and offer them an incentive to gain referrals
Something to keep in mind is to try and figure out who the ideal client is for your practice.
