About Trish Guise:
Coercive Control Expert
Trish Guise is the Founder and Principal of Forensic Coercive Control Solutions Inc. She is a forensic behavioral scientist specializing in coercive control, family violence, and post-separation abuse.
She holds a Master of Science in the Psychology of Coercive Control and has been qualified as an expert witness in this area by the Superior Court of California. Her work spans family, criminal, civil, workplace, and institutional matters.
In 2025, she was selected by Alberta Justice to develop and deliver training on coercive control and post-separation abuse to more than 160 justice professionals. She is also a Research Associate with the University of Salford and serves as a peer reviewer in this field.
About Her Work
Trish’s work focuses on identifying patterns of coercive control across documented behavior and communication.
In many cases, there is a large volume of information, including messages, emails, affidavits, and third-party records. Despite this, the situation can remain difficult to clearly explain or present.
This is often because coercive control is not identified through isolated incidents. It becomes visible when behavior is examined across time.
Her role is to bring structure to that information and identify whether the overall pattern is consistent with coercive control.
Working with Individuals and Professionals
Trish works with lawyers and other professionals to assist with the organization and analysis of complex material where patterns are not yet clearly defined.
She also works directly with individuals to support co-parenting, preparation for mediation, and understanding how patterns of behavior may be presenting within their matter.
Approach
Her work is structured, research grounded, and methodologically transparent, with a focus on clear pattern identification and accurate interpretation of documented evidence.
This work supports clearer understanding of complex situations and more informed decision making within legal and dispute resolution processes.
