  • I often tell Brian how confident we are working with Celtic. 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.
