Ernst & Young has appointed Christy Baumann as the Managing Partner of its San Antonio office, replacing the retiring Jeff Rummel. Baumann, who has 28 years of experience with the firm, aims to continue Rummel's mission of providing exceptional client service and driving regional growth.

Ernst & Young LLP has announced the appointment of Christy Baumann as the new Managing Partner (OMP) of its San Antonio office, effective April 1. This leadership transition follows the upcoming retirement of Jeff Rummel, who will conclude a distinguished 37-year career at the firm on June 30.

Baumann, a seasoned professional with 28 years of service at EY, steps into her new role with a clear mandate: to oversee nearly 1,300 professionals in San Antonio and continue advancing the firm’s mission of delivering exceptional client service. Her appointment reflects both continuity and innovation as EY positions itself for the next phase of growth in the region.

Continuity Through Transition

Jeff Rummel, who has served as San Antonio’s Office Managing Partner since 2020, played a pivotal role in guiding clients and teams through the unprecedented challenges of the COVID-19 pandemic. Under his leadership, the local EY office experienced significant expansion, more than doubling its headcount in just five years. Rummel’s tenure is marked by stability, resilience, and the strategic scaling of EY’s operations in the region.

“Jeff is an incredible leader in every regard, and I’m looking forward to building on the momentum he’s created in the city we both cherish,” said Baumann. Her appointment signals a seamless transition rooted in shared values and a deep understanding of the local business landscape.

A Career Built at EY

Baumann joined the firm in 1996 after graduating from Texas A&M University and has spent her entire professional career at EY. Before assuming the role of OMP, she served as an Assurance partner, leading large audit teams and advising clients across key industries that drive the economic engine of San Antonio and greater Texas. Her expertise and deep familiarity with the region’s business dynamics make her uniquely suited for the position.

Beyond her technical credentials, Baumann has played a central role in talent acquisition, leading recruiting efforts for the San Antonio office. She also maintains strong community ties, having contributed her time and leadership to organizations such as Junior Achievement, San Antonio Youth Literacy, and the Texas A&M San Antonio Foundation.

Vision for San Antonio’s Future

Baumann brings to her new role not only professional acumen but also a forward-looking vision. “We’re anticipating even more growth for San Antonio’s dynamic business environment, and we look forward to supporting the many local companies whose impact reaches around the globe,” she noted.

Her predecessor, Jeff Rummel, expressed full confidence in her leadership: “She has a long track record of delivering high-quality service for our clients, and her wide-ranging industry knowledge is precisely what’s needed as EY strengthens its investment in San Antonio and local businesses.”

With her appointment, EY continues to reinforce its commitment to the San Antonio market, leveraging institutional knowledge, local engagement, and a legacy of trusted leadership to chart the path forward.
