Get to know a few of the students, alumni and faculty in the Executive Program


Dr. Juan Rocca was a medical student at the University of Buenos Aires when he witnessed his first organ transplant—a mother giving a piece of her liver to her one-year old child. “It was an extremely moving experience,” he remembers. “After I saw this, I was hooked by the idea of transplant surgery, and I went looking for the best training I could find.” Dr. Rocca completed his surgical residency in Argentina and then traveled to the US for two transplant surgery fellowships—the first at Westchester Medical Center in Valhalla, New York, and the second at Northwestern University Feinberg School of Medicine in Chicago.

Though transplant surgery is individualized, Dr. Rocca recognizes that viewing his specialty through a public health lens will allow him to expand his expertise and contribute to the larger conversation surrounding prevention. “The patients that receive kidney transplants are very sick. They are on dialysis or they have cardiovascular disease, diabetes, hypertension—a lot of diseases that, from the public health point of view, are preventable. The same happens with liver transplant recipients and liver diseases resulting from alcohol abuse, viral hepatitis and obesity,” he says. “That’s the link between what I’m doing in transplant and one of the motivations for why I decided to come back to school.”

Dr. Rocca is currently balancing his career as a surgeon in the Abdominal Transplant Center at Montefiore with his studies in HPM’s Executive MHA program. He credits his cohort and professors for providing a unique learning environment. “It’s amazing to be back in the classroom,” he admits. “One of the main advantages of this program is sharing ideas with my classmates, who have different viewpoints on healthcare as a result of their backgrounds and expertise.” Dr. Rocca has found that the course content has direct applications in his practice, for example, in understanding the constraints his hospital administrators face. “Doctors and administrators tend to see things through different lenses,” he says, “and being exposed to other perspectives during class has had an immediate impact on my day-to-day work.” 

Another one of Dr. Rocca’s interests is fusing technology with public health. He is excited about the idea that future technological advancements will integrate surgical concepts in new approaches that can be standardized and shared all over the world. Dr. Rocca brings this mindset to his role as the Chair of the Clinical Policy Committee at the New York Center for Liver Transplantation (NYCLT). “The committee is always focused on the best way to improve the viability and utilization of organs—already a scarce resource. From the technological point of view, what we’re trying to do is improve organ utilization.” Dr. Rocca wants to be part of the movement that reconciles precision medicine with public health. “What I do is driven by technology,” Dr. Rocca says, “and technology is about finding creative ways to do things and spreading that advantage to others.”

Ricardo Rivera-Cardona entered the EXEC program eager to create new initiatives in healthcare for Puerto Rico. Mr. Rivera-Cardona is the Executive Director of the Puerto Rico Health Insurance Administration. In this role he manages the Government Health Plan (GHP) which serves 45% of Puerto Rico’s population with a 2.8 billion dollar budget. When he assumed the role in 2013, Rivera-Cardona had inherited a system in crisis. The agency had a projected deficit of 200 million dollars. In the last three years, Rivera-Cardona has streamlined the system, working to eliminate inefficiencies, and the organization is currently projecting a 60 million dollar surplus by the end of this fiscal year.

Since enrolling into the EXEC program, Mr. Rivera-Cardona has completed several courses which have been extremely useful in his effort to navigate challenges within the Puerto Rican healthcare system. One course, Issues and Approaches to Healthcare, has proven particularly informative. “The class provided a historical context for understanding how the US system works and the challenges and the political issues surrounding it,” Rivera-Cardona explains. “That gave me additional tools to do my job. In Puerto Rico, people are caught up in the moment, and they don’t step back to understand history, and that class taught me how to value history and to use history as a foundation in order to build a future.”

When Rivera-Cardona’s graduates from the EXEC program in 2017, he plans on moving back into the private sector. He knows that the skills he has acquired throughout his professional and academic career will help him transition smoothly into his next role. Mr. Rivera-Cardona sees opportunity to effect change in the future of healthcare. His experience eliminating the inefficiencies in organizations is a strength that he hopes to employ in his next role. “My life has been getting into challenges and then trying to turn them around, and that’s what excites me about healthcare.”

When Gina Villani was thirteen years old, her cousin died from leukemia. Villani was stunned by the disease and the swift and devastating impact it had on her family. This experience ignited her interest in medicine and drove her to pursue a career as a physician. There were no doctors in her family and no model of how to navigate the medical school applications and entrance exams. Villani’s parents were skeptical of her career choice, which only made her more resolute. “Because we didn’t have anyone in healthcare in the family and no one had ever been to medical school, we didn’t know the process,” Villani says. She applied to medical schools for four years in a row, and undeterred, kept retaking her MCATs. On her fourth attempt, she got a perfect score and was admitted to the State University of New York (SUNY) at Stony Brook. 

After medical school, Villani completed a residency in internal medicine at SUNY Syracuse and North Shore University Hospital. She did post-doctoral work in Hematology and Oncology at New York University Medical Center and Bellevue Hospital, and she worked at Montefiore in the Bronx during the height of the HIV epidemic, treating patients with HIV-related cancers. At North Shore, Villani treated patients without insurance, which sparked her interest in working with underserved populations. At North Shore, she also became a member of the Gynecological Oncology Group, studying the effectiveness of new drugs and drug combinations used to treat gynecological cancers. “It takes a lot to get people to understand what a clinical trial is,” she remarks. “It was a big accomplishment, being able to work with patients to help them understand the value of participating in clinical research.” 

As much as she valued working in a clinical setting and treating patients, Villani was eager to expand her career options. “I really like clinical medicine, but ultimately, I felt discouraged. I knew that I couldn’t keep doing it five and six days a week. I was really frustrated with the healthcare system overall.” Villani began to research her career options and decided to go back to school. She enrolled in Columbia’s EXEC program. “The program completely changed my career path,” she says, “I started to learn about the bigger picture, how the healthcare system works. It made me see that there were so many opportunities and alternatives to clinical medicine.” She also learned valuable management skills at Columbia. “I had always been a staff physician at a hospital, so management was sort of the enemy,” she jokes. She describes the relationship between the administration and the clinicians in her experience as two groups who didn’t understand each other’s roles and didn’t speak the same language. “Learning about management widened my view of the whole healthcare system.” 

After getting her MPH, Villani served as the Vice President of Health and Quality of Life for the National Urban League. There she worked on a pilot program in partnership with the Morehouse School of Medicine. The program, first implemented at the Urban League in Elyria, Ohio, paired African-American men from the community with health coaches. The coaches provided physical screenings, nutrition and fitness education to help instruct the men on ways to control diabetes and hypertension. The program was such a success that it has since been instituted in various Urban League sites around the country. 

In February of 2012, Villani was named CEO of the Ralph Lauren Cancer Center. The center was founded as a community-based facility focused on cancer prevention, diagnosis and treatment. This month marks the ten year anniversary of the center, and it continues to provide a space to treat underserved populations. Villani is proud to note that the center has expanded what is considered underserved, “It’s not just racial and ethnic minorities—it’s LGBT and the mentally-ill and other marginalized populations. We want to provide cancer prevention and treatment for those populations because they suffer disparities as well, so we’ve broadened who we are serving.” She explains that the center is not a place for large-scale clinical trials or experimental drugs. “The center’s goal is to stand as a model of how to provide cancer care in the community for underinsured, uninsured, disenfranchised people, and do it in a way that is financially responsible.” Because Medicaid pays so little for cancer care, underserved individuals don’t have access to quality care.
