In March, nearly 40 individuals from across the country will meet with their legislators to urge Congress to take bipartisan action to prioritize the battle against antibiotic resistance: a looming global health threat that threatens the future of modern medicine. As part of The Pew Charitable Trusts’ Stand Up to Superbugs initiative, this year’s ambassadors include health care professionals, public health officials, scientists, farmers and ranchers, veterinarians, superbug survivors, and people who have lost loved ones to an antibiotic-resistant infection. They will meet virtually with federal agency leaders and members of Congress to share their superbug stories and expertise, and urge increased commitment and momentum to preserve the effectiveness of existing antibiotics and develop urgently needed new ones.

She has seen the effects of antibiotic resistance within her own family: Both parents were hospitalized a month apart for methicillin-resistant Staphylococcus aureus (MRSA) infections. Although both have recovered fully, their journey to healing was a long road. During their hospitalization, both parents experienced complications related to vancomycin, the antibiotic drug of choice for treating most MRSA infections. Clarke received her Bachelor of Science in nursing from Wayne State University.
Mel Coleman Jr.
Mel Coleman Jr. was born and raised on the cattle ranch that became Coleman Natural Beef, a company founded by his father, Mel Coleman Sr. Together, they helped create standards and protocols necessary to garner the Agriculture Department’s first “natural” label, designating beef produced from livestock raised without the use of antibiotics or growth hormones.
Today, Coleman serves as vice president and spokesperson for Coleman Natural Foods. He has held numerous leadership and board positions with the Organic Trade Association, Culinary Institute of America, and American Meat Institute and was a founding member of the Organic Food Alliance.

He is also the executive committee chair for the American Farmland Trust board of directors and sits on its Growing Local Committee.
Cynthia Flora earned a master’s degree in environmental management from Duke University before there were many jobs in this field, so she moved west. Calling herself a “southeast Alaskan wilderness tramp,” she worked a variety of jobs: U.S. Forest Service worker laying out timber-cutting units, public radio operations director, gillnet crewman, and shipyard business manager. During this time, she acquired NTM (nontuberculous mycobacterium) in her lungs. Additional diagnoses followed: bronchiectasis, bronchiolitis, Sjogren’s syndrome, asthma, GERD. She lost one lung lobe and acquired a persistent multidrug-resistant infection of Stenotrophomonas maltophilia and had side effects of vertigo and brain fog. Other than that, she’s in pretty good shape. Flora chairs Nontuberculous Mycobacterial Northwest Support, where she was honored to have had Tammy Heenan as a member. Heenan was a cheerful, courageous woman who flew across the country to share her battle with NTM and pseudomonas aeruginosa at the 2020 superbug fly-in; sadly, she died from complications a few months later following surgery.

Grace Kubin, Ph.D., lost her father due to complications from a C. diff infection in June 2015. The uncontrollable infection was caused by improper prescribing of antibiotics following surgery and a lack of patient monitoring to detect the infection. The following year, the Texas Department of State Health Services Laboratory, of which Kubin serves as director, received funding from the Centers for Disease Control and Prevention to become a testing lab for CDC’s newly formed national Antibiotic Resistance Lab Network. These laboratories provide additional testing capacities to quickly identify unusual resistance and look for potential sources of resistant organisms in health care facilities. The Texas laboratory supports rapid identification in an effort to prevent antibiotic resistance, and Kubin has co-written several papers on this work. She studied immunology, focusing on gene regulation, at the University of Texas, Austin, where she received bachelor’s, master’s, and doctoral degrees.

For the next two decades, she worked as a surveillance specialist and supervised a team whose responsibilities included the monitoring and reporting of STIs, including Neisseria gonorrhoeae. Lightheart is currently Michigan’s statewide provider liaison, calling attention to antimicrobial resistance, especially as it relates to Neisseria gonorrhoeae, in the medical community.
Christian John Lillis
Christian Lillis lost his mother, Peggy, to a community-acquired C. diff infection in April 2010 after she was unnecessarily prescribed a broad-spectrum antibiotic.

In 2007, Joanna Sandager’s, B.S.N., R.N., family packed the car and drove her to the College of William & Mary to start her freshman year. But a few weeks after school started, an antibiotic-resistant staph infection put all that in jeopardy. Sandager contracted MRSA in a small cut in her leg. Her mother had recently seen a news broadcast about MRSA outbreaks in Virginia and urged her daughter to go to the emergency room. Thanks to her mom’s quick thinking, Sandager was promptly admitted to the hospital and treated with vancomycin. The infection had spread so fast that for a few days doctors considered amputating her leg. Fortunately, her treatment was successful without amputation, but the rest of her first year away from her family was spent in and out of the hospital and student health center receiving intravenous antibiotics as the infection recurred.
Sandager is a recent graduate of Virginia Commonwealth University’s School of Nursing and works as a registered nurse in Norfolk, Virginia. She feels lucky that the antibiotics available 10 years ago were successful in treating the infection, but worries about the future for her patients. She is passionate about preserving the antibiotics we have and encouraging lawmakers to protect and expand funding to spur the development of new drugs to tackle the superbugs we will face in the next decade.

Zach Withers co-owns and runs Polk’s Folly Farm, a small family-run operation in the eastern foothills of the Sandia Mountains in central New Mexico that specializes in heritage breed hogs. He also raises a small flock of laying hens and ducks and a few head of cattle. The farm diverts well over a million pounds of food waste from the landfill each year to feed its animals and uses deep bedded wood chips to absorb animal waste and food waste, which is then composted and used as soil amendment. Polk’s Folly Farm has planted a quarter-acre of apple trees and hopes to continue transforming the property into a silvopastoral food forest. It also has a small brick-and-mortar retail outlet a few miles from the farm where it does much of its own processing and sells products from a growing number of other farms and ranches. Withers’ goal is to develop an agricultural model that is specifically adapted to the ecology of its place, truly regenerative, and socially as well as economically sustainable. The farm uses antibiotics only on the very rare occasion that one of its animals gets sick and workers are unable to heal the animal using natural remedies or by addressing the underlying management issues causing the illness.
