Ob Hospitalist Group Celebrates 20 Years of Advancing Maternal Care Nationwide

GREENVILLE, S.C., Nov. 10, 2026 /PRNewswire/ -- Ob Hospitalist Group (OBHG), the nation's largest and only dedicated provider of OB/GYN hospitalist services and a leader in comprehensive women's health solutions, is celebrating its 20th anniversary, marking two decades of expanding access to safe, high-quality obstetric services for women and families across the United States.

Founded in 2006 by OB/GYN Chris Swain, MD, OBHG began with a simple but transformative vision: ensuring every expectant mother has access to timely, expert care when she arrives at the hospital, regardless of the time of day. What started as a single program with four OB hospitalists has grown into a national network of more than 2,100 clinicians partnering with over 320 hospitals across 42 states.

At the heart of OBHG's evolution is Dr. Swain's pioneering introduction of the nation's first 24/7 obstetric emergency department (OBED), a model that helped redefine how hospitals respond to obstetric emergencies. By establishing a continuous on-site clinical presence, the model helps ensure timely assessment and intervention for patients while strengthening collaboration with community OB/GYNs and supporting the broader labor and delivery team.

"Twenty years ago, OBHG was founded on the belief that every woman deserves access to safe, expert maternity care, no matter when or where she needs it," said Lenny Castiglione, chief executive officer of OBHG. "What began as one physician's vision has grown into a nationwide network of dedicated clinicians and hospital partners committed to making that belief a reality. This anniversary is a celebration of the people and progress that have defined our first two decades, and an opportunity to look ahead to how we can continue making a difference for mothers and their babies."

Over the past 20 years, OBHG has expanded its approach to maternal healthcare to address the evolving needs of hospitals and health systems, clinicians and patients. This includes prioritizing collaboration between certified nurse-midwives and OB clinicians, an approach proven to improve maternal outcomes.

Beyond OB hospitalist programs, the organization has developed flexible Maternal Health Access Solutions to support hospitals in rural and underserved communities, helping close gaps in access to full-scope obstetric care and maintain essential obstetric services locally. OBHG also connects patients with specialized care through Obtelecare, its maternal-fetal medicine telehealth platform. Additionally, OBHG's subsidiary OBstat extends this workforce support, placing OB/GYN clinicians, OB hospitalists and maternal-fetal medicine specialists in locum tenens and contract positions at hospitals nationwide. Together, these solutions help hospitals strengthen maternal safety, support their clinical workforce and maintain essential obstetric services in their communities.

That commitment is reflected in OBHG's measurable impact on access to care. According to its 2025 Maternal Health Impact Report, OBHG clinicians provided 36,278 prenatal visits to patients in maternity care deserts and supported more than 3,000 deliveries in high-need communities between August 2024 and July 2025. OBHG's recently published white paper, Safer Births, Stronger Systems, further highlights the organization's leadership in advancing the evolution of obstetric care, demonstrating how the OB hospitalist model helps improve maternal safety, strengthen care delivery and ensure patients have access to timely, high-quality care.

As OBHG celebrates this milestone, the organization is also looking toward the future of maternal health and the partnerships needed to address persistent challenges in care delivery. As a leader in the maternal healthcare industry, OBHG is bringing together experts from some of the nation's leading health systems, clinical associations and patient advocacy organizations during its National Clinical Leadership Meeting, November 9–11, held in conjunction with its 20th anniversary celebration. The gathering reflects the relationships and influence OBHG has built across the maternal health community and its commitment to bringing diverse perspectives together to shape the future of care.

The meeting's featured panel, "Leading Voices in Maternal Health," will include representatives from the President of the American College of Osteopathic Obstetricians and Gynecologists (ACOOG), the Preeclampsia Foundation, the American College of Nurse-Midwives (ACNM) and March of Dimes, which recently entered a multi-year partnership with OBHG to bring awareness to the prevalence of maternity care deserts in the United States and solutions to improve access to care. 

"Over the past 20 years, we've seen firsthand what is possible when hospitals, physicians, certified nurse-midwives and maternal health advocates work together with a shared commitment to improving care," said Dr. Lisa Bukovac, chief clinical officer of OBHG. "Bringing together so many respected leaders from across the maternal health community is a testament to the progress we've made and the importance of continued collaboration. As we look to the next 20 years, we're focused on building on that foundation to help more hospitals deliver safe, sustainable maternity care and ensure more families can access the care they deserve."

As OBHG enters its third decade, the organization remains committed to the vision that inspired its founding: advancing maternal safety, supporting the clinicians who care for women and babies and helping hospitals provide high-quality maternity care to the communities that depend on them.
