She has been married for 22 years, is the mother of two teenage boys and has a full-time job.
Like other parents, she's involved in her children's activities and finds time to volunteer with the Boy Scouts, the Athletic Boosters and PTA.
Active in her church, she sings in the choir and serves on a committee.
And if that's not enough to keep her busy, she's a Longaberger basket consultant.
A lifelong resident of Boonsboro, she is close to her parents, her sisters - who she calls her best friends - and her nieces and nephews.
Her life might seem picture perfect - except for the presence of a silent disease.
Poffenberger, 44, has multiple sclerosis.
MS is a chronic, often disabling disorder that attacks the central nervous system, which is made up of the brain, spinal cord and optic nerves. Symptoms can be mild, such as numbness in the limbs, or severe, such as paralysis or loss of vision.
It's been 13 years since Poffenberger was told she had MS, but she still recalls vividly the symptoms that led to that diagnosis.
"I remember getting out of bed on Good Friday in March of 2000 and having numbness and tingling from my waist down," she said.
Those symptoms spread to her hands, feet and, eventually, all over.
"I went through several different tests," Poffenberger said, "with everything coming back negative. But my brother-in-law, who is a dairy veterinarian and has an aunt with MS, suggested I go to a neurologist and so I did. I had an MRI and there were lesions on the brain. Then, I had a spinal tap and it confirmed the diagnosis."
Doctors at the University of Maryland Medical Center, where she went for a second opinion, supported the test results. She had MS.
Poffenberger said being told she had multiple sclerosis was something she never expected.
"However, when I got the final diagnosis, I just said, 'What do I need to do?' I wanted to be proactive and get started with a medication that could slow down the disease," she said. "At the time, my boys were young and my main concern was whether I would be able to keep up with them and their activities."
Fortunately, she said, her MS was diagnosed early so she hasn't had the problems that some people do who are fighting the disorder.
"In my case, I thank God that I have been able to continue with my children's activities and that I have, up to this point, been able to live a normal life," she said. "I've been very fortunate to have been able to keep my MS under control with medication."
Poffenberger said she has been on the drug Copaxone since her diagnosis.
