Concurrent Technologies Corporation will promote Jo O'Saben to Vice President and Chief Financial Officer and Jay Bleehash to the newly created Vice President and Chief Administrative Officer role, effective January 4, 2027, [citybiz](https://www.citybiz.co/article/929938/concurrent-technologies-corporation-names-jo-osaben-cfo-and-jay-bleehash-cao-as-john-klein-retires/) reported. The appointments follow the planned retirement of longtime CFO John Klein, who leaves his full-time position on December 31 after more than 33 years with the Johnstown, Pennsylvania-based nonprofit research and development organization.

## How Concurrent Technologies Split the CFO Job

[Concurrent Technologies Corporation](https://akta.pro/company-profiles/0005mk8/concurrent-technologies-corporation) is dividing Klein's existing responsibilities between two executive positions, separating financial management from broader administrative and operational support functions. The restructuring is intended to strengthen financial oversight, align enterprise services with strategic priorities and maintain leadership continuity as the organization advances its research and technology development programs.

O'Saben currently serves as Executive Director, Controller and Treasurer and brings more than 30 years of finance and accounting experience within CTC. As CFO, she will lead the Office of the Chief Financial Officer, overseeing finance, accounting, financial planning and analysis, treasury and risk management. She holds a Master of Science in Organizational Leadership from Geneva College and a Bachelor of Science in Economics from the University of Pittsburgh.

Bleehash will take responsibility for several enterprise support functions under the new position, including talent strategy, corporate communications and brand strategy, information technology, contracts and acquisition, and facilities and security. He currently serves as Executive Director of Talent and Brand Strategy and Chief Ethics Officer, and previously worked at the organization as Manager of Human Resources from 1993 to 2008 before moving into senior leadership positions at Bayer Corporation. He returned to CTC in 2024.

"Announcing this transition early and structuring it carefully ensures continuity for the organization," Klein said. "I have great confidence in Jo, Jay, and the entire leadership team to carry this work forward and continue driving mission success."

## Klein's Three-Decade Run at Concurrent Technologies

Klein joined CTC in 1993 as a business and financial analyst and subsequently advanced through the organization's financial leadership ranks. During his tenure, he helped oversee financial operations, organizational growth and business planning across CTC's research, development and technical services activities. Following his retirement from full-time employment, Klein will remain with CTC in a part-time advisory capacity through the end of the organization's fiscal year, or longer if needed, to support the transition.

Christopher Hamilton, President and CEO of CTC, said: "John has been a cornerstone of CTC's success for more than three decades. His steady leadership, financial expertise, and unwavering integrity have helped guide the company through significant growth and change."

## Earlier Leadership Changes at Concurrent Technologies

Hamilton became president and CEO effective June 29, succeeding Ed Sheehan, Jr., GovCon Wire reported in June 2026. In May 2026, Hans DeViso was appointed VP of the Engineering & Advanced Manufacturing Division, succeeding Timothy Tibbits, who retired after 18 years, according to akta.pro [company records](https://akta.pro/company-data). The same records show Hamilton brought 30 years of defense industry experience from Parsons Corporation, including Counter-UAS program leadership.

## When the Concurrent Technologies Appointments Take Effect

The new executive appointments take effect January 4, 2027, following Klein's departure from his full-time role at the end of December.
