It's the who, not the do.
Thinking that doing this or saying that will produce new patients is a linear, mechanistic notion that doesn't properly reflect how a practice grows. Imagining that implementing a technique or procedure will produce new patients is actually manipulative and self-serving.
Begin by clarifying why you desire new patients. Is it to help others? Or to help yourself?
If your interest in new patients is to generate income, reach a goal, pay your bills or even fill gaps in your schedule, chances are new patients remain elusive. If, on the other hand, new patients mean new opportunities to serve, introduce the truth, save others from risky drugs or irreversible surgery, new patients manifest more easily.
Prospective new patients see your heart. They detect your motives. Start there. Because all things being equal, getting new patients is more about who you are, than what you do.
