I have extensive training and experience in clinical psychology, forensic psychology, and spirituality and ministry, and apply a range of specific interventions proven to create relief and positive change for particular issues.
I seek to restore optimal life functioning in all its dimensions at school, work, and home. The tools we employ come from cutting-edge science, the healing power of the personal therapeutic connection, and historical spiritual practice. I collaborate expectantly and with commitment with those who seek healing from trauma, renewal in their relationships, freedom from destructive behavior patterns, stability in thought and mood, clarity in purpose and values, and a sharper life-focus.

Having completed dual specializations in Forensic Psychology and Clinical counseling, I trained in the psychodynamic approach.
You’re feeling fragile? We all get that way. We often don’t credit the hard work we’re doing, while focusing on perceived flaws. How relieved would you feel to let that all go, or be kinder to yourself? I’m not going to lie; it can be uncomfortable to share the most vulnerable parts of yourself with a stranger. But we won’t be strangers long. You’ll talk and I’ll listen. I’m curious and non-judgmental. You’ll find that I’m a nurturing and calming presence, and despite my professionalism I’m not afraid to joke and laugh with you. The relationship is central to our work.

Forensic Psychology Therapists

How does forensic psychology work?

Forensic psychology works by providing those in the legal system with expert information about psychology and behavior that they wouldn’t otherwise have. Forensic psychologists do this through a range of services—conducting psychological assessments for court cases, assisting police officers with investigations, providing expert opinion, helping with mediation, and providing mental health care to victims or perpetrators of crimes.

Can a forensic psychologist help with child custody cases?

Yes. In the event that it’s needed, an attorney or judge may appoint a forensic psychologist to provide an assessment and recommendation. This process involves multiple interviews with the child, the parent (or parents), and sometimes others. The psychologist assesses the parent’s mental health, strengths and weaknesses, and parenting practices to understand what’s in the child’s best interest. They then complete a report with recommendations based on their assessment.

Do forensic psychologists help solve crimes?

In some cases they do. For example, criminal profiling involves collaborating with law enforcement officers to construct a profile of a perpetrator based on psychology, personality, and behavior as suggested by the crime in order to focus the investigation. They may also offer expert input on subjects related to a case such as deception, false confessions, and the reliability of testimony based on eyewitness accounts.

How long do people typically work with a forensic psychologist?

The length of time an individual works with a forensic psychologist depends on the relevant service. For example, if a forensic psychologist is conducting a psychological assessment for a court case, this may take one to two sessions to complete (although they can be more extensive). If the forensic psychologist is providing therapy to someone accused or convicted of a crime, treatment may last for several months or more.
