How to Get 70 Referrals in One Day by Dr. Kerry Johnson There are really only about 5 ways of marketing your practice and getting affluent clients. Number 1 is to cold call. I used to make phone calls back in 1981 when I was with a stock brokerage firm. We were making about 150 cold calls every single day and we got rejected 149 times every single day. I used to call my mother in the afternoons and even she would say don’t call me again.
