If they've had a great experience at your office, bring it up, and get them feeling their results again and talking about it to others. Spreading the word about chiropractic is a big job. Create referral packets and always have this material ready to hand deliver to anyone who's interested. If you have to scramble around at the last minute to assemble these things, your office will appear unprepared and disorganized. You'll block your capacity for self-promotion and sabotage your own attempts to expand your practice patient volume.
Preparedness is the name of the game with referrals.
Don't hesitate to test the waters. Prepare yourself today and expect referrals, referrals, and more referrals tomorrow. Implement these procedures and watch your practice grow.
