TPx Communications Appoints Don Joos as Chief Executive Officer

Joos brings to TPx a deep industry knowledge and a strong track record of transforming high-tech companies.

TPx Communications, the premier managed services provider, announced today that its Board of Directors has named Don Joos, a proven leader with more than 20 years of experience in the technology industry, as Chief Executive Officer, effective immediately. Mr. Joos succeeds Joe Cozzolino, who has served as interim CEO during the board’s search for a CEO. Mr. Cozzolino will continue to serve as Executive Chairman of the Board of TPx.

Mr. Joos brings to TPx a deep industry knowledge and a strong track record of transforming high-tech companies. Most recently, he served as the CEO of PGi, the world’s largest dedicated provider of collaboration software and services, and, like TPx, a portfolio company of Siris Capital Group LLC (“Siris”). Prior to joining PGi in 2017, Joos served as President and CEO of ShoreTel, driving the strategic transformation of the business from a pure hardware solution into one of the leading cloud communications providers.

Mr. Cozzolino said, “Don has an excellent track record of driving change, performance and results in high-growth, innovative technology companies, and is well-suited to drive TPx’s strategic and operational transformation and further its mission of delivering superior managed IT solutions. As Executive Chairman, I look forward to working closely with Don to help the team achieve its strategic objectives.”

Mr. Joos stated, “I am honored to be appointed to this role during an exciting time at TPx. My focus will be on accelerating TPx’s development, building on its industry-leading customer satisfaction, tremendous range of award-winning products, and its large, diversified customer base. TPx plays an important role in serving the fast-growing addressable market for UCaaS, CCaaS and managed IT services, including security, and is aligned to expand market share. I look forward to partnering with TPx’s leadership team and employees to drive the company’s next phase of transformation.”
