WHAT WE DO
Our Services
Our wide range of evaluation types reflects the complexity of the cases we see. Each assessment is investigative, designed to examine context, history, and behavior from multiple angles to produce well-founded, defensible conclusions.
Child Custody Evaluations
Provides an objective assessment of each parent’s capacity, behavior, and family dynamics. Using a thorough, investigative approach, the child custody evaluations we produce present substantiated findings to support decisions made in the child's best interest.
Risk of Harm/Threat of Harm/Safety Evaluations
When concerns of safety or harm are raised, our psychological evaluations focus on what can be supported, not assumed. We examine behavior, history, and context to identify whether risk is present and whether the findings are defensible in court in child custody cases.
Competency Evaluations
Mental capacity and criminal responsibility evaluations assess an individual’s ability to understand proceedings and participate meaningfully in legal matters. Through a structured, objective process, we examine cognitive and psychological functioning to provide well-supported conclusions for court consideration.
Parenting Capacity Assessments
Parenting capacity assessments examine more than surface-level interactions. We evaluate patterns, history, and decision-making to determine a parent’s ability to meet a child’s needs, producing findings grounded in evidence rather than assumptions.
Pre-Adoption Evaluations
Pre-adoption evaluations assess readiness and suitability through a structured process. We examine background, functioning, and stability to ensure that decisions are informed, well-supported, and aligned with the child's long-term well-being.
Professional Testimony
Professional testimony extends the evaluation into the courtroom. Dr. Gransee presents his findings with clarity and precision, translating complex psychological data into objective, defensible statements that withstand cross-examination and are respected by both courts and attorneys.
Other Evaluations Offered:
Hardship Evaluations (I-601) \ Immigration Evaluations \ Lethal Weapons Certification (Act 120/Act 235)
OUR Process

Extensive Reference & Review
Through document analysis and collateral interviews, we provide a multi-source, multi-perspective evaluation. This is an investigative process that builds a complete picture, going beyond individual opinions to reach evidence-based conclusions.

What To Expect
Preparing For Your First Psychological Evaluation?
The forensic psychological evaluation consists of two main components: a clinical interview and psychological testing.
Our practice uses a team approach for all of our cases. Our team is comprised of Dr. Gransee as the lead clinician. He conducts the interviews for the report, supervises the processing of all information for the case, and writes the report, including conclusions and recommendations. In addition to Dr. Gransee, there are two master's-level clinicians, trained and supervised by Dr. Gransee, who comprise the research team. One clinician is assigned the task of making all collateral calls, except the main call. The other clinician is assigned to the documents and is responsible for collecting, summarizing, and reviewing the documents with Dr. Gransee. As part of this team approach, Dr. Gransee will meet with the research team during the process to confer on the case and obtain their clinical impressions. Dr. Gransee compiles all the information obtained by the research team and includes this information in the final report.
