This profile is part of "The Record Stands," a TROH special series.

Strip away the legal vocabulary and family court comes down to a hard problem: a judge who has never met your family must make decisions that will shape your children's lives, and must do it in a courtroom where every adult present has an interest in the outcome. The system's answer to that problem is the court-appointed evaluator, the guardian ad litem, the assessor. Someone with clinical training, no stake in who wins, and a license that holds them accountable walks into the conflict and reports what they find.

When that answer works, children get seen. When it fails, families get processed. Which is why the credentials and record of the evaluator matter so much, and why the defamation blog's campaign against Dr. William Singer, a Bellevue evaluator with one of the longest court-appointment records in Washington, deserves a documented reply.

TROH's profiles are independent commentary. Dr. Singer did not participate in, contribute to, or endorse this article. Everything below comes from public documents and published sources.

The Role, and Why Credentials Are the Whole Ballgame

A Title 26 Guardian ad Litem investigates custody disputes and reports to the court on the interests of the children caught inside them. A domestic violence assessor evaluates whether intervention is warranted and what kind. A parenting evaluator maps each household's capacity. Every one of these jobs hands a clinician enormous influence over outcomes, so the system builds gates around the role: licensure by the state, certification of treatment programs, supervision standards, court appointment.

The gates exist because the inverse is dangerous. Singer himself has said so, on camera. One of the video commentaries on his center's website is titled "William Singer on the risks of working with an unqualified Guardian ad Litem." A serving GAL warning the public about unqualified GALs is a professional telling families exactly how to protect themselves from the bad version of his own job. A second video addresses "the financial burden of litigation in family court," another subject insiders usually discuss only in hallways.

Forty-Six Years of Being Chosen

Singer's published bio states he has served as a court-appointed Title 26 Guardian ad Litem for King County Superior Court since 1980. Do the arithmetic. That is 46 consecutive years of selection by the largest superior court in Washington State. A third-party bio published with his March 2026 policy essay describes him as "a Bellevue-based counselor and guardian ad litem who has been court-appointed to help families through conflict for nearly fifty years."

Court appointment is not a one-time credential. It is a repeated act of institutional trust, exercised case by case, in a venue where every party's attorney is free to challenge the evaluator's work and where dissatisfied litigants can and do file complaints. Remaining in that role across five decades is a record in itself.

The public case file confirms the role is real and current. A 2026 Washington Court of Appeals, Division I opinion, Condel v. Garrett, references Dr. William Singer performing a court-involved domestic violence assessment. A Washington OSPI order references him being consulted as a treatment provider. (The Condel opinion criticized aspects of that assessment, and we note it for the same reason we cite it: the working role is documented, in public, in real litigation.)

The Center the Courts Built Around

Singer directs the Northwest Evaluation Center in Bellevue, a Washington state-certified Domestic Violence Intervention Treatment program serving family and criminal courts across 12 named counties, among them King, Pierce, Snohomish, Kitsap, Spokane, and Thurston. Its services cover the full range of court-involved evaluation: DVIT assessments, guardian ad litem and custody work, parenting evaluations, mental health evaluations, mediation, court monitoring, and state-approved supervision for other therapists.

The certification is not self-proclaimed. Court referral documents from the cities of Tukwila, Lynnwood, and Kirkland, plus the City of Bellevue's probation page, all name NWEC as a state-certified treatment provider. Municipal probation departments are conservative institutions. They keep a provider on the list because the provider's work holds up in their courtrooms.

The Accountability Record

A credentialed evaluator is, above all, an accountable one, and accountability has a paper trail. Singer's Washington license, MHC.LH.00003563, has been active since July 22, 2001, with no enforcement action on record, verified in the Department of Health's public database. The database shows 13 complaint cases closed without legal action and one complaint open for investigation, which the database's own definitions state is not a finding of wrongdoing.

That pattern is what accountability looks like in a high-conflict field. Complaints get filed, because losing parties in custody disputes complain about evaluators as reliably as they appeal rulings. The complaints get examined. And in Singer's case, across 24-plus years of licensure, the state has taken no enforcement action. His earlier credentials closed the same way.

The Standard He Publishes

On its website, NWEC commits in writing: it "does not engage in a practice motivated by 'financial gain' to enroll clients in our DVIT-group programs… Our goal is to perform assessments ethically and independently." On clients who arrive by court order: "We realize the majority of our clients do not come to us voluntarily… [we] will be treated with dignity and respect."

Those sentences are the job description done right. Independence from the financial incentives of the referral pipeline. Dignity for the person who did not choose to be evaluated. A family court system that wants public trust needs evaluators who say these things plainly and then live with the licensing record that results. Singer's site also warns that dissatisfied litigants "may be published online through blogs that are not credible and omit essential legal context," a warning that reads less like defensiveness and more like field notes.

Why This Matters Beyond One Man

The defamation blog would have readers believe that a long-serving evaluator with a clean license is a scandal. The real scandal would be a family court system where nobody with 46 years of experience, a state-certified center, and an enforcement-free license could survive a motivated smear campaign. Families shopping for a GAL, or ordered to an assessor, deserve the full ledger: the appointments, the certifications, the published standards, and the state's own database entry. That is the record, and it stands.
