“What lies behind us and what lies before us are tiny matters compared to what lies within us” ~ Henry Stanley Haskins
Before becoming a therapist, Leah spent 17 years in the classroom. That experience continues to shape the way she understands people today: we don’t all think, learn, communicate, cope, or experience the world in the same way—and good therapy should make room for those differences.
Leah works with adolescents and adults who may be struggling emotionally, trying to better understand how their brain works, recovering from difficult experiences, or feeling frustrated by strategies that don’t seem to work for them.
She also has a particular interest in supporting first responders and healthcare professionals navigating the unique demands of high-responsibility and helping professions.
Her style is gentle and empathetic, but refreshingly honest, and she brings warmth, curiosity, and practicality to her work with clients.
Leah has experience supporting clients with:
Leah starts from a simple belief: people are doing the best they can with the resources available to them.
Therapy, then, isn’t about identifying everything that’s “wrong.” It’s about understanding what’s happening, recognizing the strengths and resources you already have, and figuring out what else might help.
Leah takes a strengths-based and individualized approach, adapting therapy to the person in front of her rather than expecting the person to adapt to therapy.
This is especially important in her work with adolescents, neurodivergent clients, and individuals with learning differences, where the way someone processes information or experiences the world can be an important part of understanding what they need.
Leah takes time to understand how you think, what you’ve experienced, what’s already working, and where you’re getting stuck.
From there, therapy becomes a collaborative process of building on existing strengths and developing new ways to approach the challenges you’re facing.
Her years in education have made Leah particularly aware that progress can look different from one person to another. She brings patience and flexibility to the process, along with the willingness to be honest when something isn’t working and curious about what might work better.
This same individualized approach informs her work with first responders and healthcare professionals. Leah recognizes that people who spend their working lives caring for, protecting, or supporting others can face significant emotional demands of their own—and may not always find it easy to make space for them.
Above all, Leah wants clients to feel heard, respected, and understood while developing greater confidence in their own ability to navigate life’s challenges.
Leah provides individual therapy to adolescents ages 12+ and adults, including individuals navigating mental health concerns, neurodivergence, learning differences, difficult life experiences, and periods of significant stress or change.
She has a particular interest in working with first responders and healthcare professionals.
Leah understands that helping professions can carry unique demands, including exposure to difficult situations, high levels of responsibility, occupational stress, and the challenge of caring for yourself while being responsible for the care or safety of others.
Her background in both education and psychology can also be particularly valuable for adolescents and adults navigating ADHD, autism, learning differences, or situations where emotional and learning-related concerns overlap.

Leah holds a Bachelor of Arts from the University of Waterloo, a Bachelor of Education from York University, and a Master of Psychology from Adler Graduate Professional School in Toronto.
Before entering psychology, Leah spent 17 years teaching in Simcoe County. She later transitioned to private practice, where she provided psychological services to remote Indigenous communities across Ontario, Nunavut, and Québec.
These diverse experiences have shaped her appreciation for each person’s individual circumstances, strengths, and ways of understanding the world.
Leah is currently completing the multi-year registration requirements to become a Psychological Associate with the College of Psychologists and Behaviour Analysts of Ontario (CPBAO) and practices under the supervision of Dr. Andrea Guthrie, C.Psych.
If you—or your teen—could benefit from a therapist who brings together experience in psychology, education, neurodiversity, and learning, or you’re a first responder or healthcare professional looking for a space to focus on your own well-being, Leah may be a good fit.
