Word of mouth marketing is the act of your patrons recommending your business. You should create a culture worth talking about and then engage your patients to talk about it. You want your patient to have such a great experience at your practice, that they instantly run to tell their friends and family about how much they loved their appointment. Maybe they even make a post on their social media about how comfortable you made them feel, sharing with hundreds of their friends. The best part about this form of marketing, it's free! You just need a well-trained staff to provide excellent customer service, every time and then the referrals will start flying in.
