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.

I am a Client Advisor with J.P. Morgan’s Private Bank in Milwaukee. In my role, I focus on helping high net worth clients address their complex wealth management needs. Leveraging the resources at J.P. Morgan, I can address all aspects of financial planning, including banking, credit, estate planning, philanthropy, and wealth transfer.

Prior to the Private Bank, I worked at both Stark Investments and Racon Capital, spending much of my career as a macro analyst and product specialist respectively. Both experiences laid the foundation and provided a framework for my current work.

But my career actually started as a teacher. I was trained in Canada, spending time as a researcher prior to moving to Milwaukee, focused on the micro-interactions that take place in the classroom. During my time in the field, I published numerous articles and a spelling text book, Nelson Spelling 2.

I was born in Toronto, Canada. I have a B.A., B.Ed., and M.Ed. from the University of Toronto. In 2000, I made Milwaukee my home and currently reside in Cedarburg with my family. All three of my children have attended Montessori schools.

Head of School

“We shall walk together on this path of life, for all things are part of the universe and are connected with each other to form one whole unity.” ― Maria Montessori

Hello PMA Family! I am elated to serve as your new Head of School to support children, families, staff, and community stakeholders in achieving the highest level of excellence in our Montessori Educational Method.

As a 27-year veteran educator, I take pride in facilitating a learning environment that boasts a belief in diversity; differentiation; technological advancement; standards-driven curriculum; clarity of instruction, high expectations; and, a wealth of knowledge to provide multiple ways of knowing and interacting with each other, our community, and world. Additionally, I aim to nurture effective, caring educators who possess patience, respect, empathy, dedication, and rapport building skills to encourage strong family partnerships.
