She also goes to the University of Maryland Medical Center once a year for a checkup.
Other than that, her life is pretty normal, she noted.
"I work full time at Lanco-Pennland in Hagerstown. I am very involved in my kids' activities and in the community," she said. "I am the current president of the Boonsboro Athletic Boosters, secretary of the Boonsboro Middle School PTA and serve on Troop 20 Boy Scout Committee."
Poffenberger said her church family has always been an important part of her life. She is a member of the Contemporary Choir at Trinity Lutheran Church in Boonsboro, leads a small children's choir and serves on the Christian Education and Outreach Committee.
And there are no signs of slowing down.
Poffenberger recently was named the honorary chairwoman of the upcoming Walk MS at Antietam National Battlefield.
The fundraising event, sponsored by the National MS Society-Maryland Chapter, will be from 9 a.m. to 2 p.m. Saturday, April 27, at Antietam National Battlefield.
"I am very honored to have been chosen," Poffenberger said.
The Boonsboro resident will be among the walkers following an approximately 3-mile route, just as she has been over the past 12 years. Her team is JP's Crew, which will be made up of family and friends.
"My parents became very involved in the walk after my diagnosis," she said, "and have chaired the Hagerstown Walk for several years."
Money raised from the walk will be used to support life-changing programs and services for the more than 6,700 people in Maryland living with MS. The walk, held in 10 communities across the state, is the chapter's largest fundraising campaign.
Poffenberger said she is thankful, while dealing with MS, for the full support of her family, including her husband Mark, her sons Zachary, who will be 18 in June and will graduate from Boonsboro High School, and Zane, 14, an eighth-grader at Boonsboro Middle School.
"My sisters, parents and Mark's family have always been there when we need them," she added. "I'm also surrounded by great friends."
Poffenberger encourages anyone who is having any type of health problems to be their own advocate.
"You know your body better than anyone else," she said. "Stand up for how you feel and be persistent if things don't seem right. I remember in the beginning feeling like maybe my symptoms were not taken seriously and I knew something was not right. The more proactive you are, hopefully, you will be able to slow down the progression of the disease."
