Children and Teen Mental Health, ADHD & Autism
Kassandra Smalley
MACP, Registered Psychotherapist (Qualifying), BASc, CYC
You’ve been holding a lot for a long time.You might feel stuck in patterns you don’t fully understand, even when you’re trying to do things differently.
Maybe you feel overwhelmed, anxious, or stuck in patterns that are hard to break, especially in your relationships, your family, or how you see yourself. You might notice that certain reactions or emotions feel bigger than the situation, and you’re not always sure why.
For some, this shows up in parenting, trying to support your child while managing your own stress, self-doubt, or emotional load. For others, it shows up in people-pleasing, difficulty with closeness, or feeling disconnected from yourself.
I support individuals navigating anxiety, relationship patterns, and life transitions, with a focus on maternal mental health and neurodivergent individuals, including ADHD and autism.
My approach is attachment-informed and trauma-aware, focused on helping you better understand long-standing patterns and build more supportive ways of relating to yourself and others.
A core theme in my work is understanding how early experiences shape how we relate to ourselves and others.
This often shows up as:
Anxiety, overwhelm, and self-doubt
People-pleasing and difficulty with boundaries
Relationship patterns and attachment-related concerns
Maternal mental health, including pregnancy, postpartum, and early parenthood
Navigating neurodivergence in an affirming and supportive way
Therapy with me is collaborative, paced, and responsive. I value emotional safety, reflection, and developing insight that can be applied meaningfully to everyday life.
At its core, my work is about creating space, space to slow down, make sense of your experiences, and move forward with greater clarity and self-trust, especially during times of stress, transition, or change.

Neurodiversity-affirming support
Many of the people I work with have spent years feeling misunderstood, working hard to keep up, or wondering why things seem harder for them than they appear for others. I provide neurodiversity-affirming therapy for children, teens, and adults with ADHD, autism, and other developmental differences. Many of the individuals I work with are navigating anxiety, emotional regulation challenges, social difficulties, burnout, masking, low self-confidence, or feeling misunderstood by the people around them.
Over the past decade, I have worked across schools, treatment centres, social services, and healthcare settings supporting neurodivergent individuals and their families. This experience has taught me that there is no one-size-fits-all approach. Every person has unique strengths, needs, and ways of experiencing the world.
Many neurodivergent individuals have spent years trying to fit into environments that were never designed with their needs in mind. Over time, that can be exhausting. Together, we focus on understanding how your brain works, building on your strengths, developing practical strategies, and creating a life that feels more manageable and authentic to you.
Maternal Mental Health
Pregnancy, postpartum, and early parenthood can bring significant emotional, physical, and relational changes. While these experiences can be meaningful and rewarding, they can also leave you feeling overwhelmed, anxious, isolated, uncertain, or unlike yourself.
I support individuals navigating pregnancy, postpartum adjustment, fertility challenges, pregnancy, parenting stress, and the many transitions that come with becoming a parent. For some, this may be the first time they are slowing down long enough to notice how much they are carrying. For others, becoming a parent can bring up questions about their own childhood, relationships, and experiences of being cared for.
My approach recognizes that parenting does not happen in isolation. Our support systems, relationships, expectations, and early experiences often shape the way we experience pregnancy, parenthood, and caregiving.
Therapy can provide a space to process these changes, make sense of what you're experiencing, and identify what you need during this stage of life. You do not need to have everything figured out to reach out for support.
Understanding Patterns & Relationships
Much of my background has been working with children and youth, which has given me a strong understanding of how early emotional environments and relationships can shape the way we relate to ourselves and others over time.
Sometimes these patterns show up in relationships, in the way we respond to stress, or in the expectations we hold about ourselves and others. You might notice them as people-pleasing, difficulty setting boundaries, self-criticism, perfectionism, relationship challenges, or feeling stuck in ways that are difficult to understand.
Often, these patterns developed for a reason. They may have helped us cope, stay connected, or navigate difficult situations earlier in life. The challenge is that what once helped us can sometimes continue to show up long after it is needed.
Together, we slow things down and make sense of where these patterns come from, how they continue to show up in the present, and what might need to change. From there, we focus on building greater self-awareness, emotional flexibility, and more intentional ways of relating to yourself and others.
Whether I am working with a child, teen, adult, caregiver, or parent, I view people within the context of their relationships and life experiences. Understanding those connections is often an important part of creating meaningful and lasting change.

The Person Behind the Therapist
My path into this work has not been linear, but it has always been rooted in a deep respect for people’s lived experiences and a belief that support should be compassionate, accessible, and human.
My experiences in various roles within the helping-profession has shaped my understanding that emotional well-being is influenced not only by individual experiences, but also by relationships, environments, and access to care.
These experiences have given me a lasting understanding of how emotional environments, especially those marked by stress, inconsistency, or unmet needs, can shape how we relate to ourselves and others later in life. This foundation that continues to inform my work with the individuals I support.
