James BurnettIn his role as Director of Public Relations for Kane Communications Group, James brings his experiences as a storyteller and relationship builder to a point.

Public relations done right involves thought leadership. It involves telling clients’ stories in any and every format and style that makes them relatable and demonstrates the benefit of their service or product. Yes, there are press releases and media advisories. But understand the sky’s the limit. Also, think narrative written features, blog posts or social media entries, podcasts, even speeches and public convening.

James’s 21 years in communications work includes 16 years as an award-winning journalist for major news outlets including the Milwaukee Journal Sentinel, the Miami Herald, and the Boston Globe. At the Journal Sentinel, James was part of a team that won a National Headliner Award for reporting on urban redevelopment in Milwaukee. At the Herald, James co-authored an investigative story recognized with an Associated Press Sports Editors Award because it may have helped exonerate a college baseball player accused of a crime. And at the Globe, James was a writer in the paper’s Pulitzer Prize-winning coverage of the aftermath of the 2013 Boston Marathon Bombings. He has also been a magazine and broadcast contributor to O: The Oprah Magazine, U.S. News & World Report, CNN and NPR.

Born and raised in Southeastern Virginia – with a detour to Sicily as a child, James first moved to Milwaukee in the fall of 1998 to write for the Journal Sentinel. After 14 years away in South Florida and Boston, he and his wife and children moved back to Milwaukee to be near family in 2018.

When he is not in family-man mode or being a so-so gardener, you can find James walking his black lab Leo at any number of North Shore parks, playing basketball at the Jewish Community Center, volunteering with his son’s Cub Scouts troop, or working on his version of the great American novel.

In his professional and personal lives, James insists that relating to and accepting as many people and as many types of people as possible is the key to effective communications.

Dana has been working in the field of Montessori education for the past five years. Before transitioning to Montessori, Dana worked as a traditional K4 teacher at a private school on the south side of Milwaukee. As she explored different educational philosophies, Dana was intrigued by the Montessori Method, as it is so different than traditional educational practices. The more she learned, the more she wanted to know. Dana enrolled in AMI Primary training course at the Montessori Institute of Milwaukee in 2012.

Soon after, Dana began working as an Assistant in a Children’s House in Cedarburg, WI at an AMI Montessori School.

Dana loved working in a Montessori Children’s House classroom, and watching the children follow their interests and inspire each other. One of Dana’s favorite quotes about Montessori education is: “The secret of good teaching is to regard the child’s intelligence as a fertile field in which seeds may be sown, to grow under the heat of the flaming imagination. –Maria Montessori”
