MILWAUKEE — The latest Milwaukee Health Department data reveals a troubling reality: about 1 in 10 Milwaukee children have been poisoned by lead, with the vast majority of cases traced to contaminated rental properties built before lead paint was banned in 1978.
For the past year, our Lighthouse special reporting team has been investigating the dangers of lead exposure and the obstacles many renters face in keeping their children safe from this preventable health crisis.
A family’s ongoing struggle
Aidan Branch was hospitalized twice as a toddler for extreme lead poisoning, and though he was too young to remember those frightening days, the effects continue to shape his daily life.

“I don’t want anyone else to go through what I’ve been through,” Aidan said.

Deanna and Aidan Branch
His mother, Deanna Branch, says the lead poisoning has left lasting damage that will affect her son for the rest of his life.
“After he was lead poisoned, he was diagnosed with ADHD, ODD. He still has behavioral problems and nervous things where he can’t sit still. He’s been that way since he was two,” Deanna Branch said.

Milwaukee children face lifelong impacts from lead poisoning in rental homes
The Branch family’s ordeal wasn’t limited to Aidan. His older brother was also poisoned in their old rental home, where a health department inspection found lead contamination on walls, windowsills, and in the water supply.
“Definitely, the lead paint was the number one factor. Eating those wood chips, playing in the window sills. The paint chipping off the walls,” Branch said.

Staggering numbers reveal widespread problem
Milwaukee Health Department data from the last four years paints a concerning picture of the scope of lead poisoning in the city. Of the 81,000 children age 5 and younger who have been tested, 9,000 were found to have concerning levels of lead in their blood.
Perhaps most alarming: inspections found that 88% of these poisoned children live in homes contaminated with lead paint.
“Lead paint, long story short, is highly concentrated, and a little bit of dust in a small child can send them straight to the hospital,” said Tyler Weber from the Milwaukee Health Department.

The problem stems from the city’s aging housing stock. Weber says Milwaukee has an estimated 255,000 housing units with lead paint because they were built before 1978, when lead paint was banned.
“Overtime as homes age, does the problem get worse?” Weber was asked.
“Yes. Absolutely, it gets worse. The older the home, the longer it goes without maintenance, the worse it is,” Weber said.
Children most vulnerable to exposure
UW-Milwaukee lead expert Amy Kalkbrenner explains why children face the highest risk of lead exposure and suffer the most severe consequences.

“They’re crawling on the floor. That’s where the tiny lead particles are. Or they’re putting everything into their mouth,” Kalkbrenner said.

Lead is particularly harmful to developing brains, making children the biggest concern for health experts.
Children’s Wisconsin tests thousands of kids annually for lead poisoning. Pediatrician Heather Paradis says the effects primarily impact a child’s ability to regulate behavior.

Dr. Heather Paradis is the medical director of the Integrated Lead Program at Children’s Wisconsin.
“Some of the behavioral problems that we see do mimic things like ADHD, so hyperactivity, impulsivity, difficulties with learning,” Paradis said.
Temporary fixes for a permanent problem
Having experienced the devastating effects of lead poisoning firsthand, Deanna Branch now volunteers to advocate for other parents facing similar situations. However, she often finds herself recommending temporary solutions rather than permanent fixes.
“I have to tell them, if you see paint chipping, you have to cover it with duct tape. If there’s dust particles on the window, use a bleach wipe or swiffer mop the floor so they won’t be exposed to the dust, just putting a bandaid on the situation, not addressing the root issue, having the lead paint out of the house,” Branch said.
“What most people don’t realize when a child is lead poisoned, it’s a lifelong thing,” Branch said.

See surveillance footage of slapping incident at Riverside High School

A former Milwaukee Public Schools paraprofessional received a deferred plea agreement for slapping a special education student.
Personnel records show the paraprofessional, Demitrios Visvardis, was accused of slapping another vulnerable student a year earlier.
Milwaukee Public Schools did not report the first incident to the police, according to department records.
When family members of a special education student voiced displeasure with a deferred plea agreement for former MPS paraprofessional Demitrios Visvardis in February, they were told it was fair given his lack of prior offenses.
Visvardis was charged with battery four months earlier in connection with an incident involving Shrone Dunn, 18, of Riverside High School.
“This ain’t nothing but a slap on the wrist,” Tyrone Dunn, Shrone’s father, said during the plea hearing. “We’re looking for justice.”
Milwaukee County Judge David Borowski assured Dunn of District Attorney Erin Karshen’s ability to fully prosecute based on what was known.
But records obtained by the Journal Sentinel through an open records request raise questions about Visvardis’s history, and how much was known before the plea deal was reached.

Visvardis has no prior criminal record, but documents in his personnel file at Milwaukee Public Schools reference a 2024 accusation that he struck a special education student.
In a December 2025 letter filed after a disciplinary hearing, MPS hearing officer Natalie Fluker said the November 2025 incident involving Shrone Dunn was “the second time in a year that [Visvardis has] been accused of slapping a vulnerable student.”
The letter references findings made by hearing officer Gary Johnson during disciplinary proceedings related to the 2024 incident.
Earlier incident also involved slapping
According to the December letter, another Riverside High School staff member expressed concern to Principal Jeff Lasky after witnessing Visvardis slap an intellectually disabled student on October 10, 2024. As with the incident involving Dunn, review of security footage confirmed the allegations.

Visvardis physically kept the student on a vent near an exit on the first floor of the school building despite the student’s multiple attempts to get up, according to the letter. Describing the footage, Johnson wrote, “The student appears to scream and you turn and slap him on the face. You then exit the hallway.”
Visvardis apologized for the incident, stating it was the worst thing he’d ever done.
Milwaukee Public Schools failed to report prior incident
According to the MPS employee handbook, the district generally follows a progressive discipline model that depends on the behavior and frequency of occurrences.
Johnson found the first incident to be “especially egregious, considering the unnecessary and excessive force” used on Student A and recommended a departure from the progressive discipline model. The departure meant Visvardis would be issued a three-day unpaid suspension and required enrollment in a course in nonviolent crisis intervention.

The school district did not directly respond to questions from the Journal Sentinel about whether the police were notified of the incident in 2024. It also declined to say whether Student A’s parents were informed or what steps were taken to protect the student following the incident.
“The safety of our students is our highest priority,” Stephen Davis, a media relations manager at Milwaukee Public Schools, told the Journal Sentinel in an emailed statement. “We cannot discuss the details of any personnel matter, and the current administration would not be able to speak about how a prior case was addressed in 2024.”
But according to Milwaukee Police Department records, no report associated with Visvardis exists since January 2021 beyond the report on his arrest on November 13, 2025. That’s the day after Riverside cameras captured footage of Visvardis slapping Dunn “with an open hand to the left side of face,” according to police records.
Review hearing scheduled for this week
Visvardis is due back in court on Thursday, June 4.
According to the deferred prosecution agreement obtained by the Journal Sentinel, he will be eligible to seek employment in a “school, group home or any other place of employment where he would interact with other vulnerable people” this month, given successful completion of an anger management treatment program.

Meanwhile, the Dunn Family has filed a lawsuit against the City of Milwaukee, Milwaukee Board of School Directors, and Visvardis.

MILWAUKEE — This Fourth of July marks the 250th anniversary of the signing of the Declaration of Independence, which created the United States of America.
In honor of that milestone, the Milwaukee County Historical Society is launching a new exhibit, “We the People: Milwaukee Stories of Immigration, Citizenship, and Community,” on June 12.
What You Need To Know
The exhibit showcases the real people who came from all over the world for a better life. The people, who over time, helped shape our country into what it is today
The experience comes with audio recordings from people who immigrated to Milwaukee, and their children
A big part of Milwaukee’s history is the Great Migration of African Americans from the rural South to the Midwest in the mid-20th century. That is documented in We the People
Overall, the team at the Milwaukee Historical Society hopes the new exhibit reminds people of our similarities and shared home, as our nation turns 250
“This is the perfect opportunity to maybe tell a story that isn’t always told,” said Ben Barbera, executive director and president of the Milwaukee County Historical Society. “We can’t necessarily talk about the founding fathers. There weren’t many Revolutionary War battles here. But we can tell a story that is essential to the country.”
That story showcases the real people who came from all over the world for a better life — people who, over time, helped shape the country into what it is today.

The story starts with those who were here first.
“The Indigenous populations of Wisconsin, because without them being pushed out and forced out, we wouldn’t have immigration come to this space,” said Olivia Hoff, community programs manager for the Milwaukee County Historical Society.
The exhibit features photos and artifacts dating back centuries.
“This is a sewing kit that was made from clothing that was worn by people who came here from England,” said Janean VanBeckum, curator of the exhibit. “They were Puritans being persecuted. They came in, settled on the East Coast, and then their family moved here.”
Families from Germany, Poland, Italy and Ireland followed. Decades later, there was a surge of immigrants from Latin America, Asia and parts of Africa.

“When you start the exhibit, you get an identification card of an immigrant,” said VanBeckum. “It’s based on real immigrants, but not any particular person, and you can go around and choose your own adventure to kind of see what happens to your immigrant’s life as they move through the process of coming here and either becoming a citizen or not becoming a citizen.”
The experience includes audio recordings from people who immigrated to Milwaukee and their children.
“This is the humanistic story,” said Hoff. “It really generates empathy too because you are hearing it from the people themselves.”
The exhibit also highlights people who came to the Milwaukee area from within the United States. A major part of Milwaukee’s history is the Great Migration of African Americans from the rural South to the Midwest in the mid-20th century. That history is documented in “We the People.”
Overall, the team at the Milwaukee County Historical Society hopes the new exhibit reminds people of their similarities and shared home as the nation turns 250.

“People can realize that everyone has a similar scope of their life and that we all may be struggling to fight some of the same battles, and that by working together, creating a civic discourse, we can be less divided.”
