Kathryn Coulter Mitchell, deputy undersecretary for the Department of Homeland Security Science and Technology Directorate, will join the Cybersecurity and Infrastructure Security Agency as its new chief of staff.

She is slated to replace Kiersten Todt, who has decided step back and serve as senior adviser in order to continue her career in the private sector, CISA announced Tuesday.

Coulter Mitchell worked in both the private and public sectors for 15 years before being part of DHS. She became director of policy for an association with over 350 government contractor members. She also authored a communications strategy for the Federal Emergency Management Administration.

In her new role, Coulter Mitchell will take over Todt’s responsibilities including strategic planning and implementation, and resource allocation.

CISA Director Jen Easterly commended both Todt and Coulter Mitchell for their accomplishments. “Kiersten’s contributions to this Administration cannot be overstated – helping to transform CISA into America’s cyber defense agency, while spearheading a number of CISA priorities including collaboration with industry, corporate cyber responsibility, the stand up of our Cybersecurity Advisory Committee, and the co-creation of our People First culture,” Easterly said.

The two-time Wash100 awardee also welcomed Todt to the organization, saying “she brings the perfect combination of experience and expertise to the job, and I look forward to working with her as CISA grows and matures as an agency.”

Ronald Rowe, current assistant director of the U.S. Secret Service’s intergovernmental and legislative affairs office, is set to become deputy director in the coming months.

He will succeed Faron Paramore, who has held the role since March 2021 and will retire from the agency after a more-than-three-decade career, USSS said Tuesday.

In his present post, Lowe works with USSS partners at the federal, state and local government levels to carry out the agency’s protection and investigation duties.

The 24-year Secret Service veteran previously served as chief of staff to the now-retired James Murray and as deputy assistant director protective operations office.

His other previous assignments included work as coordinator of the National Special Security Event for a 2016 agency operation, a senior policy adviser to the White House’s intellectual property enforcement coordinator and a portfolio manager in the Office of the Director of National Intelligence.

Earlier in his career, the University of Maryland in College Park alum served as a city police officer in West Palm Beach, Florida.

Matthew Heideman has been elevated to president and general manager of Xage Security Government LLC.

In a LinkedIn post published last week, Heideman announced his promotion from his previous position as vice president of Xage’s U.S. federal arm.

Prior to joining Xage in 2022, Heideman served as director of strategic partnerships and growth at D2iQ, a role in which he worked to expand the company’s public sector business and help clients drive their infrastructure and application modernization initiatives and embrace Kubernetes. 

Earlier, he spent more than eight years as a Department of Defense business sales and delivery executive at IBM, where he managed a project portfolio and a profit and loss center valued at $40 million.

Heideman’s other previous positions include program manager and business development lead at Deloitte and business development manager at Lockheed Martin. He began his government contracting career two decades ago as a technical recruiter at TEKsystems, where he held multiple roles of increasing responsibility over nearly six years.

Andrea Marr has joined Cadmus as its new Energy Services Division lead, succeeding Terry Fry, who previously held the position.

As part of this leadership transition, Fry will assume the role of executive vice president and head of global energy strategy at Cadmus, the Arlington, Virginia-based company announced on Tuesday.

“I’m delighted Andrea is bringing her exceptional experience, leadership capabilities, and strategic insight to our energy services division,” said Ian Kline, president and CEO of Cadmus.

He also shared his excitement for Fry’s future efforts to diversify Cadmus’ work to support global utility and public sector clients with energy and decarbonization projects.

“Together, these two appointments enhance our ability to grow our impact and deliver for our clients,” Kline said.

Marr has a long history of leading business units centering utilities as well as commercial and industrial clients. Informed by a background in clean energy economy, she brings a unique point of view on urgent decarbonization challenges and the future of the electric grid.

Prior to joining Cadmus, Marr was vice president of industrial energy at Willdan Energy Solutions, a position in which she developed and conducted a strategy that drove the enterprise into new markets and boosted performance and delivery within her department.

Earlier, she served in the U.S. Navy, and in 2013, she was honored by the White House as a Champion of Change for her energy work as a veteran.

“Cadmus is home to some of the best talent collaborating with industry-leading innovators on today’s most pressing energy issues. I’m excited to be joining the Cadmus leadership team as the firm continues to grow and innovate,” Marr commented.

Marr’s appointment follows multiple executive leadership changes made by Cadmus last year. In March 2022, the firm selected Paul Lynch as chief operating officer. Cadmus also hired Robert Cherry as vice president of mergers and acquisitions and Aidan Barrett as M&A associate to position itself for future expansion.
