Why AB&C’s Team Is the Advantage Healthcare CEOs Need Right Now
Healthcare CEOs are under extraordinary pressure. Workforce shortages, cultural strain, rising competition and shifting patient expectations are reshaping what it takes to lead a health system. Solving these challenges requires more than a marketing partner—it requires people who understand how hospitals actually work.
At AB&C, our differentiator isn’t just our integrated marketing and talent acquisition model. It’s the people who built it. AB&C’s unified approach integrates patient marketing, employer branding and workforce strategy into one coordinated engine for growth. Our managing directors, Maria Mongelli and Shawn Kessler, as well as our healthcare experts have spent significant portions of their careers working in hospitals before joining AB&C.
Maria Mongelli, Managing Director, Health
Maria brings 30 years of healthcare marketing and communications experience, shaped by more than a decade working inside the Children’s Hospital of Philadelphia and Crozer Health. That firsthand experience has given her a deep understanding of how brand, culture, reputation and patient experience are formed within the realities of hospital operations.
At AB&C, Maria has built and leads the agency’s healthcare division, partnering with health systems across the country to clarify their brand, grow patient volume and strengthen market position. Her work spans such major organizations as MedStar Health, AtlantiCare, Cooper University Health Care, Phoenix Children’s, Bronson Healthcare, Mary Washington Healthcare, Nemours, HCA, Trinity Health and Rutgers Cancer Institute.
Maria is known for bringing a strategic yet pragmatic approach to healthcare marketing, building systemwide initiatives, aligning leadership around brand strategy and helping organizations communicate with authenticity in moments of growth and change.
Shawn Kessler, Managing Director, Recruitment
Shawn brings 25 years of recruitment marketing and employer-brand leadership, beginning his career at Geisinger, where he led physician recruitment marketing and gained an inside view of how workforce challenges shape clinical operations. His early exposure to the realities of staffing, culture and organizational performance informs his approach to workforce strategy today.
Since joining AB&C, Shawn has built and grown the agency’s Recruitment marketing division into one of the country’s leading healthcare-focused practices. He has partnered with health systems nationwide—including ChristianaCare, Kaiser Permanente, WellSpan Health, Guthrie Clinic and Blue Cross Blue Shield of Rhode Island—to develop employer brands, reduce vacancies, improve retention and build more resilient talent pipelines.
Shawn is also the author of Built to Attract, a practical guide for healthcare leaders on how culture, brand and employee experience fuel talent attraction and engagement. His work centers on helping organizations turn their culture into a competitive advantage—connecting who they are with the people they need to succeed.
Nikki Laska, Healthcare Account Director
Nikki brings 20 years of hands-on healthcare marketing and communications experience, shaped by her roles across such major organizations as MedStar Health, CVS Caremark, Virtua Health and the Maryland Department of Health. Her work has spanned systemwide marketing leadership, public health communications and high-stakes operational messaging, giving her a clear understanding of how healthcare organizations function on the ground.
Nikki has a rare ability to see how brand, culture and workforce truly intersect inside clinical environments. She understands the nuances of communicating with physicians, frontline staff and administrators, as well as the communities they serve, and she brings that operational awareness directly to her work at AB&C.
At AB&C, Nikki works across both the Healthcare and Recruitment marketing divisions. Her crossover role is essential to this model, ensuring message consistency, brand accuracy and strategic alignment across patient-focused campaigns and employer-brand initiatives. She serves as the connective tissue between the two disciplines, helping clients present one cohesive story to both the patients they serve and the workforce they need to attract.
Tara Moore, Associate Managing Director, Recruitment
Tara brings nearly 30 years of combined healthcare and recruitment marketing experience, including 15 years at Geisinger, where she gained a deep understanding of how patient access, frontline workflows and staff experience shape the overall health of an organization. That early exposure to the operational side of care delivery informs the way she approaches workforce strategy and client engagement today.
For the past 16 years at AB&C, Tara has been a key member within the Recruitment division, guiding clients through complex hiring challenges. Her work spans recruitment marketing and employer brand development, always grounded in an understanding of what candidates and employees experience on the ground.
As AB&C’s diversity specialist, Tara also plays an essential role in helping organizations elevate their DEI efforts. She provides thoughtful guidance on creating a culture where people feel valued, supported and empowered—an approach that strengthens both recruitment and retention.
Nancy D’Argenio, Associate Managing Director, Public Relations
Nancy brings more than two decades of experience in communications, storytelling and media relations. She began her career in radio broadcasting before moving into healthcare public relations. That early newsroom exposure strengthened her instincts for identifying compelling stories, understanding audience behavior and knowing exactly what makes the media pay attention.
Nancy went on to spend more than 13 years at Nemours Children’s Health, where she led a wide range of PR efforts for one of the nation’s leading pediatric health systems. Her work included local and national media relations, issues and crisis communications, clinical storytelling, executive visibility and the management of high-profile special projects. She has secured coverage across major outlets and is known for finding the most meaningful way to elevate a story.
Since joining AB&C, Nancy has become a key member of the healthcare team, helping organizations strengthen their reputation, communicate with clarity and share the stories that define who they are. She also plays a critical role in issues and crisis communications, helping organizations navigate sensitive situations with clarity, accuracy and confidence. Nancy excels at translating complex clinical topics into human-centered narratives that resonate with patients, communities and the media.
