She subsequently completed an APPIC-approved pre-doctoral internship at South Florida Evaluation and Treatment Center, a forensic psychiatric facility serving individuals committed by the courts as Incompetent to Proceed or Not Guilty by Reason of Insanity. During her internship, she conducted forensic psychological evaluations, competency assessments, violence risk assessments, malingering assessments, and evaluations involving serious mental illness and complex clinical presentations.

Dr. Pleshchuk has more than a decade of professional experience with the California Department of Corrections and Rehabilitation. She served as a Staff Psychologist at California Substance Abuse Treatment Facility and State Prison, Corcoran, and later as a Senior Psychologist Specialist and Senior Psychologist Supervisor at California State Prison, Sacramento, and Mule Creek State Prison. In these settings, she provided psychological assessment and treatment to individuals with significant mental illness, extensive criminal histories, aggressive or violent behavior, and complex behavioral and psychiatric needs.

At California State Prison, Sacramento, Dr. Pleshchuk served as a Senior Psychologist Supervisor within the Psychiatric Services Unit, a highly specialized setting that housed some of the institution’s most psychiatrically impaired and behaviorally challenging incarcerated individuals. Her responsibilities included psychological assessment, crisis intervention, risk assessment, treatment planning, behavioral intervention, interdisciplinary consultation, and clinical supervision. She provided consultation regarding disruptive and aggressive behavior, completed crisis and self-harm assessments, addressed threats involving identifiable individuals, and worked collaboratively with mental health, medical, and custody personnel. As a Senior Psychologist Supervisor at Mule Creek State Prison, she provided clinical and administrative leadership to multidisciplinary teams and served as a department-wide psychology consultant. She supervised and mentored psychologists and other mental health professionals, participated in quality-management initiatives, developed and implemented treatment programs, addressed aggressive and disruptive behavior, and helped ensure compliance with professional, regulatory, and institutional standards.

This extensive correctional experience has provided Dr. Pleshchuk with a unique understanding of the intersection between mental illness, behavior, criminal conduct, institutional environments, and public safety. Her work has included individuals with serious mental illness, personality disorders, substance use disorders, histories of violence, sexual offenses, and other complex clinical and forensic presentations.

Forensic Practice

Dr. Pleshchuk founded RPK Forensic Psychological and Consultation Services, Inc. in 2020. Her current forensic practice includes evaluations of adults and juveniles for Competence to Stand Trial and Represent Self, Mental Health Diversion, Violence Risk, Criminal Responsibility, PC 288.1, and general diagnostic evaluations. She also conducts psychological evaluations, provides treatment recommendations when appropriate, prepares forensic reports, and provides expert witness testimony. Every evaluation is conducted with an emphasis on objectivity, scientific integrity, and clear communication, providing opinions grounded in psychological science that assist attorneys and courts in making informed decisions.

Dr. Pleshchuk has served on criminal expert panels for numerous California counties, including Sacramento, Amador, San Joaquin, Placer, Yolo, Stanislaus, Nevada, and Solano Counties. She also provides forensic evaluations through the State of New Hampshire Office of Forensic Evaluators and has completed evaluations for the California Department of State Hospitals and Alta California Regional Center. Her forensic work includes both adult and juvenile matters, including juvenile competency, diagnostic, and risk assessments.

Dr. Pleshchuk also serves as an Expert Reviewer for the California Board of Psychology, evaluating cases involving complaints or grievances against psychologists and conducting fitness-for-duty evaluations in matters involving license reinstatement. This work gives her experience evaluating not only psychological assessments but also professional practice, ethical considerations, and adherence to applicable standards.

In addition to her forensic practice, Dr. Pleshchuk works as a psychologist in the Emergency Department for Kaiser Permanente, where she evaluates children, adolescents, and adults presenting with acute psychiatric concerns and determines appropriate levels of care, including whether psychiatric hospitalization is indicated. This ongoing clinical work allows her to maintain current experience in psychological assessment, diagnosis, crisis intervention, and the evaluation of acute mental health conditions.

Specialized Training and Expertise

Dr. Pleshchuk has pursued specialized education in adult criminal and juvenile forensic assessment. She completed a 145-hour Criminal Forensic Assessment Certificate and a Juvenile Forensic Assessment Certificate through Palo Alto University and completed training as a Neurocriminology Informed Professional through the American Institute for the Advancement of Forensic Studies. She is currently working on her Threat Assessment Certificate through Palo Alto University (to be completed in Fall 2026). Her forensic experience encompasses psychological assessment, competency evaluations, criminal responsibility, violence risk assessment, diagnostic evaluation, malingering and response-style considerations, juvenile forensic assessment, mental health diversion, and other psychological questions arising within legal proceedings.

Expert Witness, Consultation, and Work Product Review

Dr. Pleshchuk provides expert witness services and works with attorneys on both the defense and prosecution sides. Her role is to provide an objective, independent, and scientifically grounded professional opinion rather than to advocate for a particular legal outcome. She also provides litigation consultation and Work Product Reviews. When an attorney’s client has received an unfavorable psychological evaluation from another professional, she can independently review the underlying work product, examining the methodology, psychological testing, interpretation of findings, use of diagnostic criteria, application of research and professional standards, and the evidentiary basis for the conclusions. When appropriate, a Work Product Review may provide the foundation for a rebuttal report or further consultation. The purpose is not simply to disagree with another expert, but to determine whether the opinions expressed are reliable, complete, and adequately supported by the available evidence.

Education, Mentorship, and Professional Development

Dr. Pleshchuk has also served as an educator and mentor within the field of psychology. She has taught forensic psychology at the graduate level as an Adjunct Professor and has provided clinical supervision and professional mentorship to psychologists. In her current practice, she has supervised a registered psychological assistant and mentored licensed psychologists. Her commitment to education reflects her broader approach to forensic psychology: combining rigorous psychological science, clinical experience, forensic methodology, and an understanding of the legal system to address complex questions presented in legal proceedings.

Dr. Pleshchuk brings to each case extensive correctional experience, specialized forensic training, clinical practice, psychological assessment expertise, and experience working directly with attorneys, courts, mental health professionals, and other professionals involved in the legal system. Her approach is grounded in objectivity, careful consideration of the available evidence, professional ethics, and scientifically informed forensic practice.
