Michelle Thomson

Director & Principal Psychologist

B.Sc (Hons), M.Psych (Forensic), MAPS, MAAPI

Michelle is the Director and Principal Psychologist at Port Phillip Psychology, with over 30 years of experience supporting individuals and couples through complex and deeply personal challenges.

She works with adults and couples navigating issues such as infidelity, loss of trust, intimacy concerns, and ongoing conflict. Michelle is known for her ability to create a safe, non-judgemental space where clients feel understood and supported—especially when dealing with sensitive or difficult topics.

Michelle’s approach is direct, practical, and action-focused. She works collaboratively with clients to not only understand what’s happening, but to identify clear, realistic steps forward. Clients often value her honest feedback, structured guidance, and focus on creating meaningful change rather than staying stuck in patterns.

Michelle draws on a range of evidence-based therapies, including:

  • Cognitive Behaviour Therapy (CBT)
  • Acceptance and Commitment Therapy (ACT)
  • Emotion Focused Therapy (EFT)
  • Solution Focused Therapy (SFT)
  • The Gottman Method for couples therapy (Levels 1, 2 and 3 trained)

This integrative approach allows her to tailor therapy to each client’s needs, combining insight with practical strategies that can be applied in everyday life.

Michelle is highly experienced in working with:

  • Infidelity and betrayal
  • Pornography and sexual addiction
  • Sexual and intimacy concerns
  • Communication breakdown and relationship conflict
  • Blended families and life transitions

For over 17 years she has focussed her work on sexual addictions, infidelity and betrayal.  Michelle brings a high level of skill and experience to this difficult field, starting over 30 years ago completing her Masters thesis on the intent and public perceptions of sexual offenders. Over the subsequent years she has researched why people act out, it’s impact on partners and families and developed strategies to address these issues with both individuals and with couples.  She has a particular interest in supporting partners who are struggling to process their partner’s behaviours.

With a background in forensic psychology, Michelle brings both depth and practical insight to her work. She is passionate about helping clients move through crisis, gain clarity, and create meaningful, lasting change in their relationships.
