Michael Pedone is an expert at cold calling and his training is excellent. I have hired him several times to train my sales teams and I’ve trained over 1,200 sales people.
I think it’s always a good idea to continue learning especially when it from a pro like Michael Pedone.
Do yourself a favor and go sign up for his newsletter. He always puts out great stuff.
