This profile is part of "The Record Stands," a TROH special series.
There is a job in family court with a built-in guarantee that ordinary jobs do not carry: do it correctly, and someone still leaves furious. The custody evaluator, the parenting evaluator, the court-appointed guardian ad litem, these roles end with a written recommendation about where a child will live, and in nearly every case, one parent reads that recommendation as a verdict against them. Dr. William Singer's documented record places him squarely in this line of work, and it offers a useful way to think about a duty most of the public never considers: the duty to be objective when objectivity itself generates enemies.
The Documented Role
Start with what the record establishes. Per his published bio, Singer has served as a court-appointed Title 26 Guardian ad Litem for King County Superior Court since 1980. His Northwest Evaluation Center in Bellevue lists among its services DVIT assessments, GAL and custody work, parenting evaluations, mental health evaluations, mediation, court monitoring, and state-approved supervision for therapists, all serving family and criminal courts across twelve named counties. A third-party bio carried with his 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-appointed is the load-bearing phrase. These are not engagements a parent shops for. The court brings the evaluator in, and the evaluator's client, in a meaningful sense, is the court and the child, with both parents subject to findings either may resent.
What Objectivity Costs
Think about the arithmetic of the role. Every custody evaluation ends in a recommendation. Every recommendation favors one parenting arrangement over another. The parent on the losing side of that recommendation has just watched a stranger document their shortcomings in a file that will shape their child's life, and that parent is often angry, often frightened, and now equipped with a name and a license number.
What does a furious litigant do with a name and a license number? In 2026, the options are familiar: file a complaint with the Department of Health, write reviews, post accounts online, tell anyone who will listen that the evaluator was biased, incompetent, or corrupt. Some complaints raise genuine concerns and deserve full investigation. Many are grief with a case number. The evaluator cannot tell, in advance, which complaint will be which, and cannot soften a recommendation to avoid them, because softening is exactly the failure the role forbids.
The Record as Evidence
This is where Singer's documented license history becomes interesting beyond its own facts. The HELMS record for William Harris Singer, credential MHC.LH.00003563, shows zero enforcement actions across more than 24 years of active licensure. It lists 13 closed complaint cases, each closed without legal action, and one open case, a complaint approved for investigation, a status HELMS's own definitions state is explicitly not a finding of wrongdoing.
Read those numbers in the context of the job. A practitioner who has spent decades issuing custody and parenting recommendations, per the documented service list and appointment history, has generated complaint traffic. Thirteen complaints over 24-plus years in high-conflict family work is roughly what one would expect from the role itself. The state's response is the telling part: every closed case resolved without legal action, and not one enforcement mark on the license, verified by this series.
It helps to know what the state does with a complaint. Each one is screened, and those that raise a genuine licensing concern are investigated on the merits, with the practitioner's records, methods, and reasoning examined by people who do this for a living. That process is the firewall between disappointment and discipline. A recommendation a parent hates can still be competent, ethical work; a recommendation no one hates can still be sloppy. The complaint process exists to tell those apart, and in Singer's documented history it has never once produced a sanction.
Complaints, in this light, are partly a byproduct of doing the duty. A court-appointed evaluator with a spotless complaint history over decades might invite a different suspicion, that no one was ever unhappy enough to file, which in family court could mean recommendations so bland they helped no one. Thirteen filed, thirteen closed without action, zero enforcement: that is the statistical shape of a working evaluator whose conclusions the state has repeatedly examined and declined to sanction.
The Duty Itself
The duty underneath all of this is worth naming plainly. The evaluator owes the court the truth as the evidence supports it, assembled from interviews, records, and testing, delivered in writing, defensible under cross-examination. The evaluator does not owe either parent a favorable reading. Per his documented bio, Singer's training matches the assignment: a master's in child development and testing and measurements, a doctorate in counseling psychology, and reported forensic certification among his post-nominals, the last attributed to his published bio and unverified against its registry.
A court can only be as fair as the information it receives. When an evaluator bends a report toward the parent who hired pressure or away from the parent who threatens complaints, the court's information degrades, and the child's arrangement is built on sand. The system's entire value in an evaluator is the willingness to be disliked by whoever the evidence disfavors.
There is a reason the duty falls on people with deep training. Testing and measurement, child development, clinical interviewing, forensic method: each is a discipline with its own literature and its own failure modes. The evaluator has to hold all of them steady while two households, and often two sets of attorneys, pull in opposite directions. The job description sounds clinical. The lived experience, case after case, is closer to walking a ridge in wind.
The Bottom Line
Judging an evaluator by the existence of unhappy parties is like judging a referee by the existence of booing. It tells you a game was played and a call was made. The meaningful questions are what the record shows when the calls are reviewed: in Singer's documented case, zero enforcement actions, thirteen complaints closed without legal action, and one open investigation the state's own system defines as no finding.
Someone always leaves unhappy. The documented record shows who absorbed that unhappiness, case after case, decade after decade, and kept getting appointed anyway.
