TUCSON, Ariz. — L. Vance Taylor of Oxon Hill, Md., will be featured on the national broadcast of the 2010 Jerry Lewis MDA Telethon over Labor Day weekend, Sept. 5-6.

Taylor, 32, with his wife, Casey, and daughters Isabelle, 5, and Samantha, 3, will appear in a videotaped profile on the Muscular Dystrophy Association show, as well as live as a co-host on the regional telecast by WDCW, Channel 50. Preview the profile.

For the fifth year, the national Telethon will originate from the South Point Hotel, Casino & Spa in Las Vegas, beginning at 9 p.m. EDT., Sunday, Sept. 5, and running for 21½ hours.

Taylor has limb-girdle muscular dystrophy (LGMD), a genetic, progressive disease that causes muscle weakness and wasting, starting in the shoulder and pelvic areas. He uses a power wheelchair and is an active member of the MDA National Task Force on Public Awareness.

Taylor works at the Washington, D.C.-based government affairs and business development firm Catalyst Partners LLC. He co-hosted MDA's local Washington Telethon broadcast in 2008 and regularly attends Maryland MDA summer camps, where he speaks to teens about college, work, family and independent living. Dedicated to helping MDA, Taylor has visited Capitol Hill to advocate for issues of importance to the people served by the Association.

"Vance is an inspiration so we've decided to show his story again this year. He's done a tremendous job with all the work he does in helping MDA fight neuromuscular diseases," said MDA President & CEO Gerald Weinberg. "His profile is so powerful that we're sharing it again to galvanize public support for our lifesaving mission." He has shown that his disease cannot and will not slow him down."

The star-studded show is expected to be watched by nearly 40 million viewers in the United States and Canada via more than 170 television and cable stations in MDA's "Love Network." People worldwide will be able to see the Telethon live via RealNetworks at www.mda.org.

Social media followers of MDA's Twitter, Facebook and YouTube sites will be treated to a behind-the-scenes look at the show during the broadcast.
