Every business owner understands the tremendous cost involved in acquiring a customer. So when that customer (or, patient in your case) seems to disappear from the face of the earth without letting you know why, you need to find out what happened. Give them a call, or send them a series of follow-up and informational emails. These efforts do pay off, and are worth your time. Help your patients understand that you care, and that you would like to see them again. Sometimes just a friendly reminder and phone call will be all it takes to get a patient in your office again, and back on track with their health.
