The owner of a medical spa in western North Dakota was arrested this week after police discovered she had been performing medical procedures without any license at all — and, according to investigators, using one of her employee’s credentials to do it.
Kendra Cain, the owner of Royals Medical Spa in Watford City, was taken into custody Sunday following an investigation by the Watford City Police Department. Authorities say Cain falsely represented herself as a registered nurse and performed procedures she was not legally qualified to carry out.
The case came to light after a series of complaints were made about the business, which opened in September 2025 and abruptly shut its doors on January 22. According to reporting by McKenzie County Farmer, police confirmed they launched an investigation after concerns were raised by clients — including one registered nurse who ultimately alerted law enforcement.
Investigators say Cain had no medical license of any kind on record, including no nursing certification. Despite that, police allege she used a staff member’s nursing license to schedule patients, prescribe medications, and perform medical procedures — a move that forms the basis of multiple criminal charges.
An IV bag has the Coastal Infusions brand, a new local business in Corpus Christi, at AADI Home Health & Hospice Wednesday, Dec. 6, 2023.
When officers executed a search warrant at the med spa on January 22, they found a patient treatment area containing a used IV bag, tubing, syringe, needle, bandage, and an open sharps container. Police also observed what they described as fresh blood on the floor near the IV setup.
The next day, investigators interviewed a patient who was also a nurse. She told police that while receiving IV treatment at Royals Medical Spa, she had to coach Cain through the process of inserting the IV. According to the patient, Cain left a tourniquet on her arm for too long, causing her hand to turn purple. She also reported seeing air in the IV tubing — a potentially life-threatening situation that could lead to an air embolism.
Police say the patient warned Cain about the risk at the time.
Cain was arrested and charged 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 appearance is scheduled for March 26.
