MA., Ph.D (candidate), R.P(Q), CCC
Navigating the ups and downs of life in 2021 has never been more difficult. During this last year especially, ... identifying what is “normal” or makes sense for you can seem like an impossible task. Perhaps you are a young adult who just graduated, is starting a new career, or even thinking about starting a family. The simultaneous pressures of meeting ends meet living in a large city like Toronto, while also figuring out your purpose and life trajectory is difficult. Adulthood introduces many changes both good and bad. Perhaps there is a bittersweet aftertaste in your mouth as you reminisce about the joys of being carefree as a child or teen juxtaposed to the demands of “adulting”. While you may find that you are now in charge and control of all your decisions, the confusion and frustration in navigating your relationships, building meaningful connections, and planning for your future can be overwhelming. Even though you may be trying your best, it can sometimes feel as though you have no idea what you are doing, or that you are simply just getting by. Growing up is quite often coupled with anxiety and hopelessness. To quote the words of one of my favourite authors, Dr. Brene Brown, she explains that “only when we are brave enough to explore the darkness will we discover the infinite power of our light.” The decision to look for therapy and seek help is no easy task. It requires a lot of courage and the ability to dig deep and be vulnerable. As a therapist, it is my firm belief that the most important aspect of therapy is the therapeutic relationship between my clients and I, and therefore, my primary aim is to co-create a safe, collaborative, and non-judgemental space for you to explore whatever is coming up for you in session. I describe my practice as person-focused, strengths based and anti-oppressive and trauma-informed. I customize treatment depending on the client however I borrow tools from CBT, DBT, mindfulness, psychodynamic therapy as well as critical theory. I’m also a firm believer that therapy is a very spiritual space and encourage my clients to bring forward what gives them meaning, or what allows their own personal light to shine brighter. I have experience working with many clientele including children, youth, adults, couples and families and welcome people from diverse backgrounds to reach out. I completed a bachelor's in health science from the University of Ottawa and a Master of Arts in Psychotherapy, Counselling and Spirituality specializing in Couples and Family Counselling from Saint Paul University. I am also currently completing my Ph.D. in Interdisciplinary Social Research where my project is looking at youth homelessness prevention, interventions and increasing access to justice to other vulnerable populations. I hope that if you think we will be a good fit that you can reach out and allow me to accompany you on your journey.
