Greg Coyne
Sandler Training - Gerry Weinberg & Assoc.

Building a Sustainable Business Through Technology

Greg is a high-energy and enthusiastic speaker and consultant who has been actively involved with Sandler by Gerry Weinberg & Associates since 2009.  He has an additional 10+ years of success in Leadership, Management, Customer Care, & Business Development.

He has helped a wide variety of companies, in various industries, whose presidents and sales leaders were worried that their organizations were not getting them the results they wanted. They were frustrated with themselves, that they were not able to lead effectively in a remote environment; concerned that they were leaving money on the table, by giving information to companies that used it to buy from their competition; anxious that their current culture was hostile and fragmented; and worried that with those issues, their business wouldn’t give them a solid succession plan, either for themselves or their stakeholders.

Through Greg’s help, his clients learn how to use a system to build and develop their business, uncover blind spots they didn’t even realize they had, and stop wasting valuable time with people and companies who will never buy from them.
