LEWISTON — The Lewiston Auburn Metropolitan Chamber of Commerce will host the next seminar in its Mind Your Business, Business Development Series on Thursday, Sept. 29.

The Challenging Sale will be presented from 8:30 to 10:30 a.m. in the chamber conference room at 415 Lisbon St.  Presenter will be Bob Bernier of Matheson Gas Products. 

The seminar will cover the types of sales and how to prepare for each. Those attending will learn how to sell to multiple people and how to win each step of the way. This is not a sell-everyone-every-time seminar. However, it is a scientific, systematic and logical approach to selling with confidence and without the pushy salesperson stigma.

Cost is $25 for members and $50 for nonmembers. Registration is available at www.LAMetroChamber.com.
