The Greater Hall Chamber of Commerce, along with area health providers, businesses and organizations, is sponsoring the 3rd Annual HealthSmart Interactive Health & Wellness Expo.

The event, set for Wednesday at the Georgia Mountains Center in Gainesville, will feature free health screenings from 10 a.m. to 6 p.m., including tests for blood pressure, diabetes and skin cancer.

Also, more than 70 exhibitors will be set up from 1 to 6 p.m.

The event's highlight is an appearance by Phillip and Amy Parham, a Greenville, S.C., couple that appeared as contestants on the reality TV show "The Biggest Loser."

The Parhams, who lost a combined 256 pounds during the show, are scheduled to speak at 11:30 a.m.

They have appeared on the "Today Show," "Oprah" and "The Doctors" and have formed a "90-day fitness challenge" that they plan to take nationwide, according to the chamber's Web site.

A luncheon also is planned, with reservations required and the cost set at $20 person. Gainesville-Hall County's "most fit company" will be announced then.

The expo is open to the public at no charge.

Flu shots will be available for $25.
