About Nikki


I believe there is good in everyone. I also trust in the power of unconditional positive regard and I aim to provide you with a safe, judgement-free place to explore who you are and who you want to be. Recognizing that everyone responds differently to therapy, my approach is eclectic, integrative, and collaborative. I also know that life, people, and the issues we experience are complex, and so I view things holistically, incorporating your strengths and values into therapy wherever possible. Our past and our present can affect us deeply, but we can also draw on them to improve our future. Overall, I believe that therapy is not a one-size-fits-all solution to our problems, and you do not need to be “fixed.” As your therapist, I am here to walk alongside you on your healing journey, and to help shape therapy into whatever you need it to be.


I work with clients aged 11+, providing a secure, affirming, collaborative space for you to explore and make sense of your thoughts, emotions, and experiences. As a therapist, I blend tools and ideas from a variety of evidence-based therapies to help you reach your goals in a way that is effective for you. My main specialties include Schema Therapy, DBT, parts work, ACT, and EFIT, but more fundamentally, I approach all of our work together from a client-centred and trauma-informed stance.


If you have any questions or want more information on how I do individual therapy, please feel free to book a free 15-minute phone consultation with me, using the link on this page. You are also welcome to book a session if you feel ready to do so. I am here to help in any way I can!


Therapy with Nikki


Our first session is normally pretty relaxed—we’re just getting to know each other! I’ll ask a few key questions about what brings you to therapy, who is in your support system, what coping skills you use, and, of course, what your goals are for therapy. I’ll also ask about your hobbies and any cultural or religious values that you might hold dear, because I believe these things can be therapeutic in and of themselves, and I will incorporate them wherever they might be helpful.



Don’t worry if our first session feels like a great big trauma dump! That’s totally normal and can be helpful for both of us as we get to know each other and work together towards achieving your goals.
