GLENDALE — A Milwaukee County man who worked at Illume Cosmetic Surgery and MedSpa in Glendale has been charged with multiple counts of stalking and capturing an intimate representation without consent, according to Glendale police.
Prosecutors say Mark Blake, 51, was taken into custody by police on Wednesday, June 3, after executing a search warrant at the clinic and his home, according to a criminal complaint filed Sunday, June 7.

Alleged affair
The charges allegedly stem from accusations from an employee, identified in the complaint as MCF, who worked at the clinic’s Glendale location and told investigators on April 6 that she believed her boss, Blake, had been stalking her for around a year.
According to the complaint, the employee allegedly admitted to having been in a relationship with Blake but ended things in March 2024.
Initial alleged incident
Around a year later, the employee claimed to have found an Apple AirTag inside her car at the end of her shift. Prosecutors say she discovered it underneath a floor mat on the front passenger side of her car after receiving a notification about it from her iPhone.
She told investigators that she believed Blake had placed it during the workday after getting ahold of her keys from her work locker. The employee then claimed to be able to link the AirTag to Blake using the Find My app on her phone, which she said she confronted him about through text.
According to the complaint, Blake initially denied placing the tag before allegedly apologizing and stating that he was “worried about her life decisions.”
Prosecutors say the employee initially did not report the incident, believing that the behavior would stop.
Stalking allegedly continues
However, the employee allegedly became suspicious that Blake was still tracking her after she claims that, in early April 2026, he made comments indicating he was tracking her whereabouts and even questioned a co-worker about whether she was in a relationship with a co-worker, identified in the complaint as RJJ.
Court documents allege that Blake used an old iPhone 8 that he allegedly gave MCF in 2024, when she was in need of a phone for a vacation, to continue tracking her whereabouts.
In May 2026, prosecutors say investigators allegedly linked the AirTag to Blake after an examination revealed it had been bought as part of a four-pack from an Apple Store at Bayshore Mall using a credit card allegedly belonging to Blake.
Investigators also allegedly spoke to another employee who backed up the concerns, stating that Blake seemed to be “very interested in her personal life,” initially believing that MCF and Blake were having an affair.
The employee also allegedly told investigators that Blake and RJJ used to be friends and had even coached baseball together, and believed that Blake was upset because he thought MCF was in a relationship with RJJ.
Illume issues statement
In response to the allegations, Illume said a law enforcement search focused on the suspect’s conduct involving a recording device used on the premises. In a statement, Illume Cosmetic Surgery and MedSpa said the suspect has been placed on administrative leave.
“The alleged actions being investigated by law enforcement are utterly reprehensible and completely incompatible with our core values. We hold our team to the highest ethical standards, and this inexcusable conduct will not be tolerated,” Henry Behrendt, chief executive officer of Illume Cosmetic Surgery and MedSpa, said in a memo to staff obtained by TMJ4 News.
In a statement to TMJ4 News on Sunday, the company wrote, “We continue to cooperate fully with the police and other appropriate authorities. The privacy, safety and trust of our patients and employees is of paramount importance to Illume. This is an evolving situation, and we will continue to respond proactively to protect the safety and privacy of our patients and employees as more information becomes available to us.”

Court records show Blake made his initial appearance in court Monday, June 8, where a judge set his cash bond at $7,500.
His preliminary hearing is scheduled for June 18.
