OBHG Taps New Leaders to Tackle US Maternal Health Crisis

GREENVILLE, SC – January 20, 2026 – Ob Hospitalist Group (OBHG), the nation's largest provider of obstetric hospitalist services, has appointed two new executives to its leadership team, a strategic move designed to steer the company through a period of intense growth. The appointments of Aaron Cho as Chief Financial Officer and Matt Jenkins as Chief Growth Officer come as the company confronts soaring demand from hospitals grappling with a deepening national crisis in maternal healthcare.

OBHG, which partners with over 300 hospitals across 42 states, is positioning itself as a critical part of the solution for a healthcare system under strain. With these new leaders, the organization aims to scale its model of providing dedicated, in-house OB/GYN physicians to hospitals, a service that has become increasingly vital.

Navigating a National Healthcare Challenge

The demand for OBHG's services is not occurring in a vacuum. It is a direct response to the alarming state of maternal health in the United States, which faces the highest maternal mortality rate among high-income nations. Compounding the issue are the expanding "maternity care deserts"—regions lacking any obstetric care providers. More than a third of U.S. counties now fall into this category, leaving millions of women without local access to essential prenatal and delivery services.

This crisis is largely fueled by a confluence of economic and demographic pressures. A persistent and worsening shortage of OB/GYNs, projected to create a deficit of over 5,000 specialists by 2030, has left many communities vulnerable. This is exacerbated by widespread staffing shortages of nurses and anesthesiologists, which cripples the ability of hospitals, particularly in rural areas, to maintain safe and financially viable labor and delivery units. Consequently, over 100 rural hospitals have shuttered their obstetric services in the last five years, forcing expectant mothers to travel greater distances for care, which is often linked to poorer health outcomes.

It is within this challenging landscape that OBHG's model has found fertile ground. By embedding nearly 2,000 clinicians directly into hospitals, the company offers a lifeline to institutions struggling to provide consistent, 24/7 maternal care, aiming to improve safety, reduce physician burnout, and restore access where it has been lost.

A Strategic Leadership Overhaul

To manage this expansion responsibly, OBHG has brought in seasoned executives with proven track records in high-growth healthcare environments. Aaron Cho, the new CFO, arrives from Eyemart Express, where he was instrumental in guiding the national optical retailer through a successful sale and integration. His experience managing financial strategy for private equity-backed organizations is seen as crucial for navigating OBHG’s next phase of mission-driven, scalable growth.

Joining him is Matt Jenkins as Chief Growth Officer, who brings over 15 years of experience from healthcare services organizations. Most recently, Jenkins held senior development leadership roles at SCA Health, a division of UnitedHealth Group's Optum. At SCA Health, he was deeply involved in multi-market expansion efforts and deploying significant capital to expand care access, working closely with health systems and physician partners. This background directly aligns with OBHG’s goal of aggressively but thoughtfully scaling its model to meet the relentless demand from hospitals.

These appointments mark a significant transition for the company. Outgoing CFO Kevin Krenzke and outgoing CGO Marc Kerlin, both of whom have been with OBHG for more than a decade, are remaining with the organization to support a smooth handover. This move signals a planned evolution, leveraging the foundational work of its long-serving leaders to launch a new chapter of growth.

"OBHG was founded to ensure hospitals and communities have access to high-quality maternal care, and that mission continues to guide our growth," said Lenny Castiglione, Chief Executive Officer of OBHG. "As demand for our offerings increases, it's critical that we scale in a way that preserves clinical excellence and long-term value. Aaron and Matt bring the leadership we need for this next chapter, and we are deeply grateful to Kevin and Marc for more than a decade of leadership that helped build the foundation we have today."

Scaling Solutions for Broader Access

OBHG's strategy extends beyond simply placing more doctors in more hospitals. The company is actively developing a suite of services tailored to the specific needs of its partners. Its core OB hospitalist programs establish a constant presence of board-certified OB/GYNs, ensuring that every expectant mother who arrives at the hospital is seen immediately by an experienced physician, a critical factor in preventing medical emergencies from becoming tragedies.

Furthermore, the company is innovating with programs like Maternal Health Access Solutions (MHAS), which provides clinic support and call coverage to bridge care gaps in underserved communities. This initiative directly targets the problem of maternity care deserts by bringing expertise closer to patients. Complementing this is Obtelecare, a maternal-fetal medicine platform that leverages telemedicine to connect high-risk patients with specialists, regardless of their location.

The effectiveness of this multi-pronged approach is reflected in the company's rapid expansion and its growing roster of hospital partnerships, from urban medical centers to rural facilities like UPMC Western Maryland, which recently partnered with OBHG to revitalize its in-house OB/GYN coverage. With its new leadership, OBHG is poised to accelerate the deployment of these solutions, executing a disciplined strategy focused on performance, partnership, and expanding access to high-quality maternal care across the country.
