Our Therapists

Therapist, RSW
Patrick O'Halloran
Patrick specializes in helping people work through trauma, depression, anxiety, and addictions. He uses an informed, yet relaxed approach to help the therapy process feel accessible. This approach helps many individuals who are new to, unsure or uncomfortable with the idea of counseling.
He uses a combination of therapeutic techniques, knowledge of neurobiology, physical health, and our nervous system to help people identify and challenge behaviours, reactions, and patterns they want to change or improve. This approach often connects well with first responders, military, and health professionals.
He also frequently supports individuals in learning to healthily process and manage emotions as well as those struggling with shame, boundaries, relational conflict and low self-worth among other challenges.
​
Patrick has been trained in using various trauma therapy techniques, Polyvagal Theory, Internal Family Systems, EMDR, Emotion Focused Family Therapy, CBT, DBT, and Motivational Interviewing.
​
Patrick sees individuals aged 16 years and older.

Patrick is a registered provider for clients covered through Blue Cross and N.I.H.B.
