One referral I gave that has the potential to become multi-generational began when I wrote an endorsement letter for a professional in my network. Rather than simply making an introduction, I took the time to document my experience with their expertise, professionalism, and commitment to serving their clients.
I believe this referral could become multi-generational because the endorsement letter serves as more than a recommendation. It creates trust before the first conversation ever takes place. When someone receives exceptional service after being referred, they are much more likely to share that experience with others in their own network. Those individuals may then become clients and, in turn, refer additional people.
