Texas Oncology Expands Role of Jason Shook to Chief Operating Officer and Chief Financial Officer

Shook’s new role includes oversight of finance, operations, and administration to support delivering leading-edge cancer care to patients.


DALLAS (Jan. 25, 2021) – Texas Oncology announced today the promotion of Chief Financial Officer Jason Shook to an expanded operational role as both chief operating officer and chief financial officer. In this new role, Shook will oversee the operational and administrative needs of Texas Oncology’s practice and service lines while maintaining responsibility for overall financial management, including financial planning and analysis, tax, treasury, accounting, and reporting.

J. Ernest Sims, who previously served as chief operating officer and managing director at Texas Oncology, will maintain the position of managing director with responsibility for physician recruitment, governance, and strategic planning while continuing to shepherd the growth of the Texas Oncology Foundation.

“As the practice experiences significant growth, we will look to proven leaders like Jason and Ernie to apply their considerable management expertise to guide us,” said Steven Paulson, M.D., president and chairman of the board, Texas Oncology. “We are strengthening our organization for a dynamic and challenging future in healthcare and oncology care with a leadership structure that supports and fosters our focus on providing leading-edge care to patients.”

Shook joined Texas Oncology as chief financial officer in 2018 after serving as vice president and chief financial officer for The US Oncology Network and Practice Management business within McKesson Corporation.

“The beginning of a new year often brings important transitions, and I am pleased to start this year on a positive note with exciting new goals and challenges in taking on the expanded role of chief operating officer for Texas Oncology,” said Shook.

As the practice continues to adapt to the dynamic environment of the COVID-19 pandemic in 2021, Texas Oncology remains committed to implementing operational changes to support and prioritize safely caring for patients who need cancer treatment. These adjustments include regular assessment of appointment protocols, screenings processes, telemedicine use, and more to ensure Centers for Disease Control and Prevention (CDC) guidelines are followed in every aspect of its operational response to COVID-19.
