Psychological Testing & Evaluation Services

Comprehensive, Evidence-Based Assessments by Dr. Lucas Klein, Ph.D.

At Dr. Klein Psychology, we offer comprehensive and compassionate psychological testing services to help individuals, families, and professionals gain a clear understanding of mental health, personality, and cognitive functioning.

Every evaluation is written with precision, clarity, and care, ensuring that patients, parents, and attorneys understand both the evidence for or against a condition and the individual’s unique developmental or circumstantial needs.

We proudly serve all of San Diego County — including Rancho Bernardo, Del Mar, Rancho Santa Fe, Poway, Ramona, and surrounding areas — as well as clients in New York (NY), Connecticut (CT), Idaho (ID), and Oregon (OR), where Dr. Klein is licensed to practice.

Our Psychological Testing Services

Personality Testing

Gain insight into enduring patterns of thought, emotion, and behavior that shape relationships, work, and overall well-being. Personality testing supports therapy, self-understanding, and personal development.

Diagnostic Evaluations

When symptoms overlap or a clear diagnosis is uncertain, psychological testing can provide answers. These evaluations identify conditions such as depression, anxiety, ADHD, bipolar disorder, and trauma-related disorders, and they guide effective treatment planning.

IQ & Cognitive Testing

We offer intellectual and cognitive assessments to measure reasoning, memory, problem-solving, and attention. These evaluations are helpful for educational planning, developmental clarification, or workplace accommodations.

Forensic Psychological Evaluations

Dr. Klein conducts forensic evaluations for both criminal and civil court matters. These include competency and criminal responsibility assessments, psychological injury evaluations, and other court-relevant analyses. Reports are objective, comprehensive, and written to the highest professional standards.

PTSD & Veterans’ Evaluations

Our practice provides detailed PTSD evaluations for veterans and civilians. Each assessment examines the presence and impact of trauma-related symptoms, often used to support disability claims, legal proceedings, or treatment planning.

Leadership & Executive Evaluations

Designed for professionals and executives seeking to enhance leadership, management, and interpersonal skills, these evaluations highlight emotional intelligence, communication style, and opportunities for personal and professional growth.

Our Approach

Each psychological assessment is individualized and evidence-based. Reports are written in clear, accessible language, avoiding unnecessary jargon, and designed to inform treatment, decision-making, and understanding.

Many of our evaluations are requested by psychiatrists, psychologists, attorneys, and other professionals who rely on Dr. Klein’s thorough and balanced reports for treatment guidance and expert consultation.

We believe that effective psychological testing does more than diagnose — it provides a pathway to insight, clarity, and meaningful change.
