Aaron left us suddenly and far too soon on March 19, 2026. His infectious, ever-present smile will be deeply missed by all who knew him.

Aaron was born in Madison, Wisconsin on November 7, 1978 and moved to Whitefish Bay in 1986. He attended Whitefish Bay public schools graduating in 1997. Growing up, he was a dedicated athlete, playing baseball, track, and football. He continued his football career at the University of Wisconsin–Eau Claire, where he earned a degree in Human Resources and met his future wife and best friend Jamie; they married in August 2004. 

Following college, Aaron worked in Milwaukee at House of Harley and the Milwaukee Mile; In 2009 he moved with his family to Green Bay to begin a thirteen year career with the Green Bay Packers; which ultimately brought him back to the Milwaukee area (and Whitefish Bay) to open a new Milwaukee based office for the Packers. 

Aaron was a devoted husband and an exceptional father to Reggie (18) and Calvin (13). He was endlessly proud of his boys and happiest when spending time with them— he would do whatever they wanted, just to be together. He was beyond proud of Calvin’s theatrical talents, admiring his bravery on stage and was a built-in audience for Calvin’s daily comedy; they were always laughing. He loved watching Calvin run at track meets, and challenging his exceptional skill at yard games. He bonded with Reggie over sports, playing catch with some kind of ball or object whenever possible. He loved coaching Reggie in youth baseball and football and especially enjoyed watching as a proud parent Reggie's senior year of high school football. Aaron showed up for everything—every game, meet, and performance— cheering and clapping really loud.

Aaron was also a loving son to Jill and Rick Hart, and a loyal friend to many. He was known by all to be generous, optimistic and just plain fun. He was a good listener and always ready to help his friends.

Professionally, Aaron later founded Evergreen Partnerships, where he worked with businesses on brand navigation in sports. He was a board member for the Vince Lombardi Cancer Foundation and was engaged with several other organizations over the years as an active member of his community.

He was a regular guy who loved life—his family, music (especially the Grateful Dead), the outdoors, hiking, biking, grilling out, and tackling projects around the house. One of his favorite traditions was grilling with other dads at high school baseball games for The Blue Dukes, where he was involved in supporting youth sports.

Through their sons’ schools and activities, Aaron and Jamie built a wide circle of close friends in Whitefish Bay. His friendships spanned a lifetime, including the friends he grew up with who were like brothers, his college buddies and Dewey Street roommates, and fellow dads from Bay.

Aaron is survived by his wife of 21 years, Jamie; his sons, Reggie and Calvin; and his parents, Rick and Jill; along with aunts, uncles, cousins, in-laws, nieces and many dear friends. He was preceded in death by his grandparents, Bill Hart, Ellie Wruck, Helen Davidson, and Ed Davidson.

If you knew Aaron, you loved him. His voice, his laugh, and his spirit were larger than life. In honor of Aaron, go about your days like he would with enthusiasm, laughter and kindness. The world has lost a truly wonderful person, but his legacy will live on in the hearts of all who knew and loved him.

In lieu of flowers, a GoFundMe has been established for his sons, Calvin and Reggie at www.gofundme.com/honoring-aaron-harts-memory-with-love.

A celebration of life will be held Friday, May 15th, open house from 3:00 - 6:00 pm, at the Italian Community Center, 631 E. Chicago Street, Milwaukee; filled with stories, tears and laughter, just as he would have wanted.
