Get involved. The easiest way to get involved in your community from a referral marketing standpoint is to identify one or two charities that you would like to support. Keep in mind that support does not mean simply writing a check. Referral marketing is heavily grounded in building strong relationships whether it’s with patients, referring doctors, or a charitable organization in the community. You must get involved, attend the meetings, meet people, and let the natural course of people liking you create a presence that leads to increased referrals and starts.
