A North Dakota medical spa owner has been taken into custody following revelations that she was operating without a valid medical license.

Kendra Cain, who owns Royals Medical Spa in Watford City, was arrested on Sunday after an investigation by local authorities. As reported by the McKenzie County Farmer, the Watford City Police Department discovered that Cain was not licensed to carry out the procedures promoted by her spa. The police alleged that Cain used a staff member’s credentials to book appointments, prescribe medications, and perform medical interventions.

The investigation was reportedly prompted by a tip-off from a registered nurse who alerted authorities to Cain’s suspected illegal activities.

According to the McKenzie County Farmer, Royals Medical Spa began operations in September 2025 but abruptly shut down on January 22. Local police confirmed that they launched an investigation after receiving multiple complaints about the business.

Authorities accused Cain of posing as a registered nurse qualified to perform various medical procedures. However, investigators discovered that she had no record of holding any medical license, including a nursing license. Allegedly, Cain exploited a staff member’s license to execute tasks that legally required certified documentation.

Upon executing a search warrant at the spa on January 22, officers found a patient treatment area with a used IV bag, tubing, a syringe, a needle, a bandage, and an open sharps container. The police also noted the presence of fresh blood on the floor near the IV setup.

The next day, police spoke to the Royals patient who was also a nurse. She told police that while she was receiving treatment at the med spa, she had to “coach” Cain as she inserted an IV. The patient claimed that Cain allegedly left the tourniquet on her arm for too long, causing her hand to turn purple. She told police that while the IV was inserted, she observed air in the tube, which she noted could result in an air embolism that had the potential to cause fatal complications.

Police arrested Cain and charged her with reckless endangerment, unauthorized use of personal identifying information, deceptive writings, and practicing as a nurse without proper certification. After being booked into the McKenzie County Correctional Facility, she was released from custody. Her next court date is scheduled for March 26.
