Training & Experience

My Commitment

I provide multiculturally competent, diversity-sensitive, scientifically informed psychotherapy and counselling techniques in an accepting, supportive, honest, and encouraging therapeutic environment. In-session you will experience genuine, empathetic, non-judgemental therapeutic exploration of whatever it is that may be troubling you. Working together with each client from a holistic, biopsychosocial, Person-Centred perspective on health and wellness, it is my goal to help you achieve a state of higher wellbeing and grow into the best version of yourself, beginning at the core with your thoughts and feelings.

Education & Experience

I hold a Master’s degree in Counselling Psychology, a B.A. (Honours) in Psychology, and a Nutritionist Diploma. I specialize in helping those suffering from anxiety, phobias, depression, relationship issues, diversity-related concerns (cultural, racial, religious, gender identity, sexuality), professional/academic-related stress, relationship issues, sex therapy, and body-image-related concerns and behaviours.

My Approach

I work with clients from a Person-Centred foundational theoretical orientation of empathic understanding, authentic communication, and unconditional positive regard to offer empirically supported psychological tools and techniques. I have additional certifications and training in CBT, DBT, and Solution-Focused therapy, as well as postgraduate education and experience using ACT techniques and mindfulness-based strategies. I offer clients the best-practice interventions of these psychotherapeutic modalities through treatment plans tailored specifically to each individual client based on their presenting problems, personal preferences, experiences, and worldview.

Before joining the team at Newmarket Therapy Centre, I worked with a community policing centre in Vancouver’s Chinatown to address and remediate a variety of sociocultural and psychological concerns. I then moved back home to Ontario where I worked as a therapist in the counselling services office of a public university.

Nutrition Counselling

In addition to psychotherapy services, I also provide nutritional counselling to my clients. You can learn more about integrating nutritional counselling as part of your treatment plan by checking out my Blog on “Nutrition and Cognitive Functioning.” You will learn about the impact nutrition has on your mood, including the role of inflammation.
