A Space to Pause, Reflect, & Grow

I’m Kate Mostar, a Registered Social Worker supporting individuals, couples, and families through mental health challenges, relationship transitions, and family reorganization. I provide counselling in Squamish and virtually across British Columbia.

Have you ever felt like you're simply getting through each day on autopilot? Maybe your mind is constantly racing, your nervous system always seems to be on high alert, or you find yourself putting everyone else's needs before your own without really knowing how to ask for what you need. Perhaps you keep finding yourself in the same relationship patterns, feeling disconnected from yourself, or wondering why certain situations affect you so deeply.

Therapy offers an opportunity to slow down, make sense of these experiences, and better understand the patterns that have shaped the way you think, feel, and relate. I work with youth, adults, couples and families using a warm, collaborative, and practical approach, I help clients develop greater self-awareness, strengthen their relationships, and move from automatic survival patterns toward responding with greater intention, confidence, and choice.

About Kate

A warm, practical, and compassionate approach to counselling

I’ve called the Sea to Sky corridor home for over 10 years and feel incredibly grateful to live and work in such a beautiful and connected community. When I’m not working, you’ll usually find me outside hiking, biking, or trying to keep up with my dog, Jude. Spending time in nature helps me feel grounded, regulates my nervous system, and reminds me of the importance of slowing down and being present in my life.

I believe that healing often begins when we feel truly seen and understood. My role is to provide a safe, supportive relationship, where clients can develop insight into how their experiences have impacted their lives and explore new ways to interact with their world.

My Background & Experience

I hold both Bachelor and Master of Social Work degrees and have spent the past 13 years supporting youth, adults, and families across a variety of settings, including community mental health, child protection, crisis services, and alternative school environments.

In addition to my private practice, I work with Vancouver Coastal Health’s Youth and Young Adult Mental Health Team, supporting individuals experiencing moderate to severe mental health concerns including trauma, anxiety, depression, OCD, eating disorders, suicidality, and substance use.

My clinical experience has provided me with a broad understanding of how mental health challenges, trauma, relationships, and family systems intersect. Being present with individuals and families through some of life’s most difficult transitions has shaped my approach to counselling, with a focus on understanding each person within the context of their relationships, experiences, and strengths.

Supporting Individuals & Families Through Change

My areas of focus include anxiety, depression, ADHD, trauma, eating disorders, relationship difficulties, family conflict, and major life transitions.

I also bring diverse experience supporting families navigating separation, divorce, and family reorganization. Through my work in child protection, I have supported families experiencing high-conflict dynamics, mental health and substance misuse, communication breakdown, parenting challenges, and significant changes in family structure.

I understand that separation is not simply the end of a relationship—it is a major transition that impacts identity, attachment, parenting roles, and the way families function. My goal is to help individuals and families adjust to these changes with greater understanding, communication, and mutual respect.

My Therapeutic Approach

My approach is warm, down-to-earth, and practical. I strive to create a space where individuals feel deeply understood and seen while offering honest reflection, gentle challenging and incorporating evidence-based interventions. Together we will tailor sessions to fit your unique needs using EMDR, CBT, DBT, and Emotion-Focused Family Therapy (EFFT).

ADHD & Neurodivergent Support

As someone with lived experience of ADHD, I understand the realities of navigating a world that is not always designed for neurodivergent minds.

Alongside counselling, I offer ADHD Coaching and practical strategies that are tailored to individual strengths, challenges, and goals. My focus is not only on managing symptoms, but also on education, self-compassion, and developing strategies that work within the context of each person’s life.

My Philosophy

I believe many of our deepest wounds occur within relationships—and that healing often happens there too. Therapy offers a space to understand the experiences that shaped you, recognize the patterns that may keep you stuck, and move from simply surviving toward being more present and engaged in your own life. My hope is to support you in creating healthier relationships with yourself, others, and the world around you.
