Sarah Marquette

Clinical Director and Registered Psychotherapist - Qualifying

Hello, I am Sarah, the creator of Guiding Compass Psychotherapy and Wellness and a Registered Psychotherapist (Qualifying) with over 25 years of experience supporting people across the lifespan. I offer a safe and supportive space for healing and growth in the heart of Port Perry. I specialize in helping children, teens, adults, couples, and families navigate anxiety, trauma, relationship challenges, and the complexities of neurodivergence with compassion and understanding.

Using evidence-based approaches such as Dialectical Behaviour Therapy (DBT), Psychodynamic Therapy, and Emotionally Focused Therapy (EFT), I tailor each session to meet your unique needs and goals. My work focuses on helping you uncover patterns, strengthen emotional resilience, and create meaningful, lasting change.

Whether you’re feeling overwhelmed, stuck in unhelpful cycles, or simply ready to explore a deeper sense of self, therapy offers a chance to reconnect—with yourself and others. Together, we’ll work toward clarity, confidence, and inner peace, guided by your own values and strengths.

You don’t have to face life’s challenges alone. Let’s take the first step toward healing, connection, and authentic living—one guided compass point at a time.

Olivia Hahn

Registered Psychotherapist - Qualifying

As a Registered Psychotherapist - Qualifying, I provide a warm, collaborative space where adults, teens, and couples can explore life’s challenges and work toward meaningful change. My background — which includes experience in both the military and helping professions — has shaped my deep respect for resilience, adaptability, and the courage it takes to seek support.

I work with clients navigating anxiety, depression, trauma, self-doubt, and relationship challenges. My approach is warm, collaborative, and nonjudgmental, creating a space where you can be truly heard and supported. Grounded in Cognitive Behavioural Therapy (CBT) and Person-Centred approaches, I tailor each session to meet you where you are. Together, we’ll identify unhelpful patterns, build coping strategies, and develop self-awareness to create greater balance and fulfillment.

My goal is to support you in discovering your strengths, building resilience, and living a life that feels authentic and aligned with your values. Whether you’re adjusting to life transitions, seeking emotional clarity, or striving for healthier relationships, I’m here to walk alongside you with compassion and understanding.

I look forward to helping you navigate your journey toward healing.
