Brian Kelly Motz, the Frederick, Maryland dentist who owns Monocacy Valley Dental, was sentenced on May 15, 2026 to three years in the Frederick County Adult Detention Center after pleading guilty to two counts of second-degree assault involving domestic violence and admitting he had violated probation in an earlier harassment case. The cases involved three different women he had been in relationships with, and the sentencing followed a fresh arrest that occurred while he was on home detention awaiting trial.1Yahoo News.

The May 2026 Sentence
Judge Joanie Raymond Brubaker imposed ten years on each assault count with all but 18 months suspended, and two years and nine months on the probation violation with all but 18 months suspended. The active portions run consecutively, producing a three-year jail sentence, with 167 days of credit for time already served. After release, Motz faces five years of supervised probation and must complete a domestic violence prevention program.1Yahoo News. Frederick Dentist to Serve Nearly 3 Years
From the bench, Judge Brubaker noted that Motz had failed an earlier attempt at a domestic abuse program and had once shown up to a court hearing intoxicated. She warned that without treatment he would “leave a wake of victims,” and told him, “You’re not good for anyone until you fix what’s going on inside of you.” Motz gave a brief apology.1Yahoo News.

The Assault Cases Behind the Plea
In November 2025, Motz was charged with eight counts of second-degree assault. The accuser, a woman he had been in a relationship with, described physical abuse spanning September 2024 to October 2025, including choking, punching, kicking, and harassment.2Yahoo News.

After posting bail in January 2026, Motz was placed on private home detention with GPS monitoring, allowed out only for work, legal appointments, and probation meetings.3Yahoo News.

On March 22, 2026, the same woman reported that after a verbal altercation at his home, Motz threw her cellphone at her when she returned to retrieve it, striking her eyebrow and drawing blood, then dragged her into the house and hit her with both hands. A responding Maryland State Police trooper observed injuries consistent with her account. Motz was charged with second-degree assault and false imprisonment, and Judge Scott Rolle ordered him held without bail, saying home detention had not been effective and that Motz was a danger to the community.4Yahoo News.

The Protective Order and Countercharges
The woman in the assault cases obtained an interim protective order on October 21, 2025, followed by two temporary orders. On December 5, 2025, the court granted a final one-year protective order for domestic violence, ordering Motz not to abuse, threaten, or contact her, barring him from her residence, and requiring him to surrender all firearms to the Frederick County Sheriff’s Office. He appealed on December 10, 2025, but the appeal was dismissed on January 7, 2026, by Judge Scott Rolle after Motz failed to appear.2Yahoo News. Updated: Frederick Dentist Accused of Assault
Motz separately filed charges of his own against the woman, alleging forgery, a theft scheme, and theft of roughly $7,000 from his business account. His attorney called her abuse allegations “retaliatory,” tied to Motz’s decision to repossess a vehicle he had bought for her and to pursue a civil suit over the money. The state declined to prosecute the charges Motz brought.5DrBicuspid. Trial Postponed for Dentist Accused of Assault
The Earlier Cases
Motz’s criminal record began in Washington County, where he faced charges tied to his conduct toward an ex-girlfriend, Roxanne Sours. The two dated from July 2020 through an on-and-off period ending in January 2022. On April 7, 2022, both Sours and a Maryland State Police senior trooper delivered letters to Motz telling him to stop contacting her. He was charged with misusing a phone to make repeated calls to annoy and harass, misdemeanor harassment, and a felony count of identity information fraud. The fraud charge stemmed from a $1,589.99 Affirm Financing loan for Netgear equipment taken out in Sours’s name, with Motz’s cell number listed on the application.6Herald-Mail Media.

On March 23, 2023, Motz entered an Alford plea to the phone misuse charge before Judge Mark D. Thomas, receiving probation before judgment, a $500 fine, and one year of supervised probation. The harassment and fraud charges were placed on the stet docket. Judge Thomas ordered no contact with Sours or her family, banned Motz from her home and workplace, and required a mental health evaluation and any recommended treatment. He had no prior criminal record at the time.6Herald-Mail Media. Maryland Dentist Brian Motz Accused of Harassing Ex-Girlfriend Gets Probation
A second harassment case followed in Frederick County involving his ex-fiancée. In April 2025, Motz pleaded guilty to misusing a phone to repeatedly call and harass her. A grand jury had indicted him on four additional counts, including electronic communication with intent to harass, repeated harassment, cocaine possession, and unauthorized use of a credit card; the state dropped those under the plea agreement. He was sentenced to 90 days in jail and five years of supervised probation, and began serving the jail time on April 25, 2025. His sentencing memorandum had argued against incarceration on the ground that he was the sole owner of Monocacy Valley Dental and that closing it would cost 12 employees their income and health benefits.7Yahoo News.

Dental License Status
As of June 2025, the Maryland Board of Dental Examiners website showed no public disciplinary actions against Motz’s license, and the board declined to say whether any investigation was underway. Around that time, Monocacy Valley Dental posted a “leave of absence” while he served weekend jail time, with plans to resume normal hours on June 17, 2025.7Yahoo News.
