A former dental assistant at a Chandler, Arizona pediatric dental practice, Deion Garcia, was sentenced on July 17, 2026 to 40 years in prison followed by lifetime supervised probation for sexually abusing three young patients, ages 4 and 6, during dental procedures between 2022 and 2024. The practice's owner, Dr. Walter Villanueva, was separately indicted in May 2026 on a felony charge of failing to report suspected abuse, and the Arizona State Board of Dental Examiners has barred him from personally treating minors since early 2025.
What are the key facts of the case?
The case centers on Kidiatric Dental and Orthodontics, a pediatric practice near Arizona Avenue and Chandler Heights Road in Chandler. Here are the verified numbers, each with its named source.
- 40 years plus lifetime probation: the sentence handed to Deion Garcia, 29, in Maricopa County Superior Court on July 17, 2026, for one count of attempted child molestation, one count of sexual conduct with a minor, and two counts of attempted sexual exploitation of a minor.

- 3 victims, ages 4 and 6: children abused during routine dental procedures, including X-rays and treatment under anesthesia, according to prosecutors. Source: FOX10 Phoenix, July 17, 2026.
- 1 felony indictment for the practice owner: Dr. Walter Villanueva was indicted on May 6, 2026 for allegedly failing to report a 2022 complaint that a parent brought directly to him. Source: azfamily.com, May 6, 2026.
Why wasn't Garcia stopped after the first 2022 report?
Because, according to prosecutors, the practice did not escalate an initial complaint to police. A mother told Dr. Villanueva in 2022 that Garcia had inappropriately touched her 6-year-old daughter during an X-ray exam, but Villanueva allegedly never contacted law enforcement, according to azfamily.com's reporting on the May 2026 indictment. Garcia was not arrested until 2024, after the parents of a second 6-year-old reported inappropriate touching to Chandler police. That investigation led detectives to photographs connecting Garcia to additional victims, including a 4-year-old who had been treated under anesthesia.
What discipline has the practice owner faced?
Dr. Villanueva has not been criminally charged with abuse himself, but he has faced two separate consequences. In a consent agreement reported in February 2025, the Arizona State Board of Dental Examiners required him to employ chaperones for all minor patients at his Chandler and Gilbert offices and barred him from personally treating anyone under 18 until Garcia's criminal case concluded, according to ABC15 Arizona's coverage of the board order. Board President Dr. Anthony Herro did not mince words about the failure of supervision.
"This is about as heinous and horrific as it gets. Although Dr. Villanueva didn't commit these acts, in my mind, he was complacent with it." Dr. Anthony Herro, President, Arizona State Board of Dental Examiners
Separately, Maricopa County Attorney Rachel Mitchell addressed Garcia's sentencing directly, framing it as a betrayal of the trust parents place in dental staff.
"This defendant was trusted with the care of vulnerable children during routine dental procedures, and he exploited that trust for his own sexual gratification." Rachel Mitchell, Maricopa County Attorney, quoted by KTAR News, July 17, 2026

Is the practice still open, and is the dentist still facing charges?
As of Garcia's July 2026 sentencing, Dr. Villanueva's failure to report case remained an open felony matter in Maricopa County, and his license restrictions from the dental board's 2025 order were still in effect. Parents with current questions about the status of a specific practice or provider's license should check directly with the Arizona State Board of Dental Examiners, which publishes disciplinary actions and license status for every licensed dentist in the state.
What should parents ask before a child's next dental visit?
Parents should ask whether staff are ever alone with a child during exams or sedation, whether the office has an open-door or observation-window policy for treatment rooms, and whether a parent may stay in the room. A child abuse prevention trainer quoted by azfamily.com noted that Arizona law sets a low bar for dental staff to act: "reasonable belief, which is the lowest standard," is enough to trigger a legal duty to report suspected abuse. Parents can also check a dentist's disciplinary history through the state dental board and look up reviews and verified details for pediatric practices, such as Oak Mountain Pediatric Dentistry in Birmingham or other listings on this directory, before booking a first visit.

Frequently asked questions
Was Kidiatric Dental and Orthodontics itself charged with a crime?
No. The practice as a business was not criminally charged. Garcia was criminally convicted and sentenced as an individual, and Dr. Villanueva was separately indicted for failing to report suspected abuse and separately disciplined by the state dental board.
Is Dr. Walter Villanueva still facing charges?
Yes, based on reporting through Garcia's July 2026 sentencing, Villanueva's felony failure to report case filed in May 2026 was still active in Maricopa County court, and his license restrictions remained in place.
What is a mandatory reporter in dentistry?
Dentists and dental staff are mandatory reporters under Arizona law. They must notify law enforcement or child protective services when they have a reasonable belief a child has been abused, a legal standard a child abuse nonprofit trainer described as the lowest bar in the law.
How can parents check whether a pediatric dental office is safe?
Ask about chaperone policies, whether parents may stay in the treatment room, and check the state dental board's website for any disciplinary history tied to the dentist or practice before a first visit.
