Psychodiagnostics

What Psychodiagnostics does

Psychodiagnostics is a privately held psychology practice headquartered at 10 Sycamore Avenue in Ho Ho Kus, New Jersey, with a second location at 218 Lorraine Avenue in Upper Montclair. Founded and operated by Dr. Steven C. Hertler, a licensed psychologist in New York and New Jersey, the practice specializes in psychological assessment, formal diagnosis, and mental health consultation across six domains: personality, mental illness, behavioral disorders, developmental disabilities, intelligence, and academic/learning disabilities. Its clinical methodology is built around a six-step differential diagnosis framework and the use of standardized, norm-referenced instruments including the Wechsler Intelligence Scales, Stanford Binet, NEPSY, Rorschach methods, continuous performance tests, and the Wisconsin Card Sorting Task, combined with customized test-battery construction and personalized narrative reporting. Specialized offerings extend to MENSA intellectual assessment, ETS SAT/GRE accommodations testing, independent child study team evaluations, custody/competency/guardianship evaluations, and trauma/PTSD assessments.

The practice operates a sales-led, fee-for-service model billed directly or through accepted insurance plans including Cigna, United Health Care, United Behavioral Health, Oxford, Blue Cross Blue Shield (PPO), Optum, and Qualcare. It serves three customer segments: individual patients and families in New Jersey and New York, other psychological and psychiatric practices that contract for complex assessment work, and schools/agencies requiring independent evaluations. The practice generates demand through an educational content website, Zocdoc online scheduling, and professional referral networks anchored by Dr. Hertler's concurrent institutional roles as principal diagnostician at Newark Beth Israel Medical Center Children's Hospital, district psychologist for East Newark School, and consulting psychologist for Psychological Group of Northern New Jersey. Total clinical staff is approximately three individuals.

Psychodiagnostics has no institutional funding, no parent company, and no disclosed external ownership structure. The business is founder-operated with revenue mechanics entirely dependent on Dr. Hertler's clinical capacity, supported by a licensed social worker and an early development specialist. Distribution is regional across NJ/NY, with two physical office locations and supplemental digital channels; pricing is not publicly disclosed and varies by insurance arrangement.

Core offering

Psychodiagnostics is a private psychology practice that performs comprehensive psychological assessments across personality, mental illness, behavioral disorders, developmental disabilities, intelligence, and academic/learning domains using standardized and norm-referenced instruments combined with observation and history. It delivers formal differential diagnoses via a six-step methodology, provides narrative reports that describe the examinee rather than the test, and offers consultation, second opinions, and treatment planning guidance.

Product overview

Psychodiagnostics is a private psychology practice offering three core services: Psychological Assessment, Psychological Diagnosis, and Mental Health Consultation. Assessment services measure six primary domains: personality, mental illness, behavioral disorders, developmental disabilities, intelligence, and academic/learning disabilities. The practice specializes in differential diagnoses distinguishing between closely related conditions, comorbid presentations, and rule-outs. Specialized assessment offerings include gifted/talented evaluations, MENSA testing, ETS accommodations (SAT/GRE), custody and competency evaluations, and trauma/PTSD assessments. Services are provided by Dr. Steven C. Hertler along with a licensed social worker and early development specialist. The practice serves New Jersey and New York residents with two office locations in Ho Ho Kus and Upper Montclair, New Jersey.

Scale indicators1 record

Recent moves1 record

Expansion highlights5 records

Broad incumbents

• Lifestance Health: Public outpatient mental health platform operating hundreds of clinics across the US with thousands of clinicians. Comparable because it delivers the same outpatient psychiatric and psychological assessment/therapy services Psychodiagnostics provides, but at vastly greater scale and via employed-clinician (rather than owner-operator) model.
• Mindpath Health: Outpatient psychiatric and mental health practice group operating across multiple US states with employed clinicians. Comparable because it offers the same assessment, diagnosis, and therapy services as Psychodiagnostics but with a multi-clinic, multi-state footprint.
• Talkiatry: Tech-enabled psychiatry practice group with hundreds of psychiatrists delivering assessment, diagnosis, and medication management across multiple US states. Comparable as a scaled outpatient mental health practice that competes for the same diagnostic-referral pipeline Psychodiagnostics serves.

Emerging players

• BetterHelp: Largest online therapy platform serving millions of users via subscription-based telehealth. Comparable because it competes for the same mental health patient pipeline Psychodiagnostics targets, though at a vastly lower price point and without the in-person assessment specialization.
• Octave: Mental health practice group offering therapy, psychiatry, and couples counseling in select US markets with an employed-clinician model. Comparable because it bundles assessment-adjacent outpatient services under one brand, directly competing for the same patient segment Psychodiagnostics serves.
• Talkspace: Public online therapy and psychiatry platform offering assessments and ongoing treatment via telehealth. Comparable because it competes for the same self-pay and insurance-funded patient population seeking mental health services, though via a fully digital rather than in-person delivery model.
• Two Chairs: Therapy practice group combining employed clinicians with a hybrid in-person/telehealth delivery model in select US metros. Comparable as a private-practice-style outpatient mental health operator pursuing the same differentiated, high-touch care positioning as Psychodiagnostics.
• Cerebral: Telehealth mental health platform providing therapy, medication management, and ADHD assessment. Comparable as a tech-enabled competitor pursuing the same ADHD/learning disability assessment referrals Psychodiagnostics relies on, but at national scale and lower price points.

Others

• Headway: Marketplace and practice-management platform that helps independent therapists and psychologists accept insurance and grow their caseloads. Comparable as an enabling infrastructure layer that could either threaten Psychodiagnostics by aggregating competing clinicians or serve as a scaling path for its own growth.
• Lyra Health: Mental health benefits platform contracted by employers to deliver therapy, coaching, and assessment services to employees. Comparable because it controls the employer-sponsored referral channel that increasingly determines where patients seeking assessments are routed — a direct threat to Psychodiagnostics' traditional referral pipeline.
