Exhibit 99.3

January 14, 2020

Dear Valued Client,

As you may have seen, CTG today announced that it has received a new unsolicited proposal from one of its shareholders, Assurance Global Services LLC (AGS), to acquire the Company for $7.00 per share in cash. A copy of the press release we just issued in response is attached.

As the CTG Board of Directors did with AGS’ prior proposals, consistent with its fiduciary duties and in consultation with its advisors, the CTG Board will carefully review and consider AGS’ new proposal to determine the course of action that it believes is in the best interest of the Company and CTG stakeholders. The Board expects to respond to the AGS proposal in due course, and we will update you following this review.

Until then, please be assured that today’s news will have no impact on our operations or how we conduct business with you. We remain focused on meeting and exceeding your needs. You can continue to expect the same high-value IT solutions and services that you have come to rely on from CTG.

I understand that you may have questions about this announcement. Please reach out to me at Filip.gyde@ctg.com, or our CFO, John Laubacker, at john.laubacker@ctg.com.

You have been an important part of CTG’s success and we look forward to continuing and building our relationship. Thank you for your business and continued support.

Sincerely,

Filip J. L. Gydé

President and CEO
