For a groundbreaking offering in the treatment of substance use disorders, ChristianaCare’s Family Medicine residency program team received a Wellness Hero Award in the 2024 Delaware Lt. Governor’s Wellness Leadership Challenge.


ChristianaCare was recognized for creating “a comprehensive program designed to address the pressing need for behavioral health services in Delaware.”



ChristianaCare’s Family Medicine residency established a substance use disorder treatment program in 2020 to identify and provide targeted substance abuse treatment to patients in need and, importantly, to train future providers in the specific and unique issues that patients with addiction often face in primary care settings.


“The purpose,” said James LaRosa, M.D., associate residency program director, “is to create an eager and competent workforce of providers ready to help this population.” LaRosa, an alumnus of ChristianaCare’s Family Medicine residency, is also lead for the Family Medicine substance use disorder treatment program.

“James was intentionally recruited to our program to carry the torch for this important work,” said Erin Kavanaugh, M.D., FAAFP, chair of Family and Community Medicine.


“He has taken the program and department to new heights, particularly in terms of grant-funded work and educational opportunities, all anchored in dedication to comprehensive patient care and improved outcomes.”


“Family medicine practitioners take a holistic approach so patients receive personalized and consistent care for better health and well-being for them and their communities,” said Anna Filip, M.D., FAAFP, director of the residency program. “With opportunities like the substance use disorder treatment program, we are preparing the next generation of doctors to treat the whole person.”


At the 2024 presentation, then-Lt. Gov. Bethany Hall-Long praised the program for “its impact on closing the gaps in treatment capacity for those with substance use disorders” and “taking measurable steps to expand access to care in our community.”


The primary goal of the program is to support patients through withdrawal, LaRosa said. Patients identified for the program via ChristianaCare’s hospitals and emergency departments are connected with the Family Medicine Department to open the door to primary care. The program also provides vital social supports for these patients through the robust ChristianaCare network.


“We utilize the services of our in-house social work, behavioral health and case management teams to help provide wraparound services to a population where those things are as crucial as the medical care,” LaRosa said.

Third-year resident Deanna Gorgei, D.O., said she chose ChristianaCare’s Family Medicine residency for its “forward-thinking and innovative leadership” who support residents in exploring their interests in the field. One of her interests in addiction medicine.


“Not only are residents like me getting this experience in how to treat different substance use disorders, but we’ve also gained exposure on how to set up a program like this,” she said.


“It’s been a huge part of my training and has shaped my interest going forward.”


Family medicine provides an especially effective setting to treat substance use disorders, in part because its providers are qualified to identify and treat comorbid conditions like hepatitis as well as a host of other illnesses and injuries.


“Since starting the program,” said LaRosa, “we have stabilized multiple patients’ chronic medical conditions, identified and treated a patient with bladder cancer, and cured 26 cases of hepatitis C.”


Combining care for substance use disorder with primary care, said Gorgei, is appealing for residents and fosters better patient experience and outcomes. “I like being able to have both opportunities,” she said. “It’s so beneficial to have addiction medicine rotate with routine primary care, because it is primary care.”

ChristianaCare Advances New Health Campus in Camden, Delaware to Close Care Gaps featured image

ChristianaCare Advances New Health Campus in Camden, Delaware to Close Care Gaps

ChristianaCare has taken another major step to expand access to high quality care across Delaware by submitting a Notice of Intent to the Delaware Health Resources Board to develop a new health campus in Camden. Like the Georgetown campus announced in February, the proposed campus will include a health center and a neighborhood hospital and is part of the $865 million statewide commitment announced last July. “For many people in central Delaware, getting timely emergency or specialty care can still mean long drives or long waits,” said Janice E. Nevin, M.D., MPH, president and CEO of ChristianaCare. “We are investing in facilities that bring care closer to where people live. This campus reflects our commitment to ensuring every Delawarean, no matter their ZIP code, can count on timely, compassionate, high-quality care close to home.” Closing Care Gaps in Central and Southern Delaware The approximately 38,000‑square‑foot Camden campus will be located on the west side of Route 13, just south of Lochmeath Way. It is expected to open in late 2028 or early 2029 and will bring primary care, specialty care and outpatient services together in one location, supported by eight emergency department beds and eight inpatient beds. The project will create 83 new jobs for the community, including 60 positions at the neighborhood hospital and 23 at the health center. Kent and Sussex counties are both designated as Medically Underserved Areas by the Health Resources and Services Administration. At the same time, the region is growing quickly. By 2030, the population in central and southern Delaware is expected to increase by 8 percent, with residents aged 65 and older growing even faster, by 22 percent. Shortages in primary care, behavioral health and specialty services have forced many residents to travel long distances for care. The Camden campus will help change that by bringing essential services closer to home. Expanding Capacity on a Strong Foundation The Camden campus represents a $58.1 million investment and reflects ChristianaCare’s focus on access, coordination and community need. ChristianaCare already provides a broad range of services in Kent County, including primary care, specialty care, behavioral health, rehabilitation, home health, hospice and virtual care. The Camden campus will build on this foundation by increasing capacity and making care more convenient as demand grows. Partnering to Deliver Care Close to Home ChristianaCare is partnering with Emerus Holdings, Inc. on the neighborhood hospital component. Emerus is the nation’s leading developer of this model, with 49 acute care facilities across the country. “Communities are stronger when people can depend on care close to home,” said Vic Schmerbeck, CEO of Emerus Holdings, Inc. “We are proud to partner with ChristianaCare to deliver a neighborhood hospital that provides high quality care in a setting designed around the needs of the community.” Growing Access Across the Region The ChristianaCare Georgetown campus is planned for 20769 DuPont Boulevard at an estimated cost of $65.1 million. ChristianaCare is also expanding this innovative care model beyond Delaware. In July 2025, the system opened a neighborhood hospital at its West Grove Campus in southern Chester County, Pennsylvania. Additional campuses are planned in Springfield and Aston in Delaware County, Pennsylvania.

ChristianaCare Forms Joint Venture For Cardiovascular Ambulatory Surgery Center featured image

ChristianaCare Forms Joint Venture For Cardiovascular Ambulatory Surgery Center

ChristianaCare, Cardiovascular Physicians of Delaware and its partner organization, US Health Partners, have formed a joint venture to establish a new cardiovascular ambulatory surgery center in Newark. This new facility will be launched through the ChristianaCare Atlas ASC partnership. This is a pivotal moment showcasing the power of a local health system, strength of a national ASC management company, and expert community-based physicians working together to deliver a lower cost, easy-to-access model of care to our community. “The ChristianaCare Cardiovascular Surgery Center at Newark represents a deep partnership between ChristianaCare and community cardiovascular experts who are truly committed to caring for this region,” said Kert F. Anzilotti, M.D., MBA, chief physician executive and president of The Medical Group at ChristianaCare. “By working side by side with trusted community physicians, we are aligning expertise and decision making to strengthen heart care across the region and ensure it continues to evolve with the needs of the people we serve.” “By expanding access to outpatient heart care, we can reduce wait times, improve the patient experience and lower the overall cost of care—while using our hospital resources more wisely and preserving capacity for patients who need complex or urgent cardiac services,” Anzilotti added. “With over 30 years of providing cardiac care to Delaware residents, we are proud to collaborate on this center,” said Brian Sarter, M.D., president of Cardiovascular Physicians of Delaware. For patients, this is about getting the right care, in the right place, at the right time. Patients will receive specialized heart care in a focused setting designed for same day procedures, with a smoother experience, faster recovery and seamless coordination with hospital care if it’s ever needed.” “This joint venture brings together ChristianaCare and Cardiovascular Physicians of Delaware’s strong clinical leadership and a proven outpatient care model,” said Aaron Snyder, M.D., chief executive officer of US Health Partners. “Our aim is to build and run a center that is efficient, reliable and patient-focused from day one, so physicians can focus on care and patients can count on a high-quality same-day experience close to home.” Reducing the Cost of Heart Care Ambulatory surgery centers lower the cost of heart care by safely moving appropriate procedures out of the hospital and into a more efficient outpatient setting. Most patients return home the same day, while hospitals preserve capacity for complex and urgent cases. As reported in Ambulatory Surgery Center News, outpatient procedures performed in ambulatory surgery centers cost 30 to 40 percent less than the same care delivered in hospitals, improving access and efficiency as demand for heart care continues to grow. The move also frees up limited hospital resources to better care for people with more complex or urgent cardiovascular needs. Meeting a Growing Need for Heart Care Heart disease remains the leading cause of death in Delaware, and demand for cardiovascular care is rising. According to the Delaware Population Consortium, the number of New Castle County residents age 65 and older is projected to increase by 23 percent by 2035, increasing pressure on cardiovascular services. Forecasts show outpatient heart and vascular procedures could reach nearly 10,800 annually for New Castle County residents by 2029 and more than 24,000 across the broader region, according to health care analytics firm Sg2. At the same time, hospital operating room capacity remains limited. Cardiovascular Physicians of Delaware’s many decades of experience in Newark and across the state positioned the group as a natural fit for the collaboration. Focused on Same Day Cardiovascular Care Expected to open in late 2027, the nearly 9,000 square foot center will be located on the second floor of the HealthCare Center at Christiana, across from Christiana Hospital. The center will focus exclusively on outpatient heart and vascular procedures. Services will include diagnostic heart catheterizations, coronary and peripheral vascular interventions, ablation procedures, pacemaker/ implantable defibrillator implantations and other minimally invasive cardiovascular procedures. Hospital based cardiac care will continue to be available for patients who need inpatient treatment, emergency care or more complex services. Other Details The project will cost an estimated $9.3 million and is expected to create 14 full time jobs across clinical, administrative, leadership and support roles. The facility represents an additional investment beyond ChristianaCare’s previously announced $865 million commitment to Delaware, reinforcing the organization’s focus on expanding services and improving health outcomes statewide. Key features of the surgery center include two new cardiac catheterization/ electrophysiology labs, dedicated pre operative and post anesthesia care space and on site sterile processing and administrative areas. Atlas Healthcare Partners will manage and operate the center, while Cardiovascular Physicians of Delaware will provide clinical oversight and perform outpatient surgical cases. ChristianaCare and Atlas Healthcare Partners formed the joint venture in 2024 to build an ambulatory surgery center network across the Mid-Atlantic region.
