Years of experience



Success Stories

"Terry taught me how to develop relationships in a very non-threatening manner, nurture and ask questions without being an interrogator, how to ask business appropriate questions no matter how sensitive the subject might be, and how to be a consultative salesperson."


Commercial Griffin Companies

"I've worked with the Slattery system for 15 years and our organization has for a lot longer. It's one of the fundamental reasons we have been so successful at acquiring new clients as well as keeping existing customers. I'd highly recommend Terry and his system to anyone trying to take their sales organization to the next level."


CEBS, REBC Associated Financial Group

"Terry Slattery's insight into determining what the differentiating value of your product or service is versus your competitors has been transformative for me in my selling career. I have worked with Terry for over 25 years. His methodology to understand a customer's pain and what they are giving up by not doing business with you is genius."
