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.
