Celtic is a full-service advertising and public relations agency based in Milwaukee's Historic Third Ward.

We help our clients engage with customers by building strong, meaningful brands that deliver powerful results.

  • What truly sets Celtic apart is their ability to know the client industry and to ultimately become a part of the client team. Celtic does not simply supply a product – they participate in the process, take ownership, and most importantly they provide the professional guidance that only comes from years of experience and a commitment to excellence.

  • They “get” us, and work right alongside us, demonstrating a genuine dedication to our mission and strategic objectives. They always bring their practiced and objective eye to our marketing, advertising, social media and media relations activities. And that ensures we can effectively tell our story to all audiences. Celtic’s counsel and expertise is invaluable to Milwaukee Irish Fest.

  • For the last eight years, I’ve had the opportunity to work with Celtic on numerous projects including PR, videos and website development. They have been part of many of our strategic planning sessions and a key player in communication in our industry. Celtic plays an important role in representing our company and I would highly recommend them for all of your communication needs.
