Deciding to seek therapy is an important step toward healing, personal growth, and meaningful change. If you are reading this page, thank you for considering the possibility of me guiding and supporting you on this journey of positive change. In working with you, I will help you navigate life obstacles by providing you with coping strategies ad a compassionate space to resolve your issues. I am pleased to present a summary of my education, the types of presenting concerns that I assess and treat, and how we would work together to help you determine if we might be a good client-therapist fit. 

I am currently in my final year of my PhD in Clinical & Counselling Psychology at the University of Toronto. At the Centre for Interpersonal Relationships, I am a resident working under the supervision of Dr. Lila Hakim, C. Psych. Here, I provide individual and couple therapy for adults presenting with a wide range of concerns and welcome people from all walks of life (e.g., different ages, genders, ethnicities, spiritual beliefs, and sexual orientations).

In terms of individual therapy, I see clients who are experiencing anxiety and depression and past or present relationship difficulties. I also support clients dealing with trauma or PTSD, and grief and loss, such as a relationship break-up, divorce, bereavement of a loved one, and the loss of a pet. I have extensive experience helping clients with life adjustment difficulties (e.g., starting college/university, relocation, retirement), occupational stress, and burnout.

Regarding couple therapy, I work with couples to address a diverse range of relationship issues, including improving their communication and physical/sexual intimacy, managing conflicts over parenting, extended family members and finances. I also support couples in managing challenging life situations in which one partner is afflicted with mental health difficulties or chronic illness.

During our initial sessions, I’ll ask you about your current life challenges and goals for therapy. Next, I’ll ask you to complete various self-report questionnaires and ask you to share your life history. This will help us understand what is causing and maintaining your difficulties. It will also allow me to systemically plan a treatment and select interventions that address your presenting concerns, unique needs, and treatment goals. 

In therapy, I use various treatment modalities, including psychodynamic therapy, emotion-focused therapy, attachment-based therapy, relational therapy, and mindfulness-based therapies. Furthermore, I believe in using an integrative approach to help people address a wide range of issues. This is a therapeutic approach in which a variety of techniques are combined to fit the unique needs of the individual client and allows for a personalized approach to treatment. Throughout the assessment and treatment process, I provide a non-judgmental, compassionate, and authentic space to help you feel comfortable discussing your problems and exploring your experiences, thoughts, emotions, and behaviours.

In my previous clinical positions, I trained in various settings, including hospitals, universities, and private practice. Specifically, I completed practicum placements at the Centre for Interpersonal Relationships, an outpatient unit at Toronto General Hospital, and the University of Waterloo’s Health Services. I have also worked in private practice in Aurora and Barrie for over six years under the supervision of registered psychologists. At these sites, I collectively treated adults and adolescents and provided individual and group therapy. I also conducted assessments for a wide range of mental health difficulties (e.g., anxiety, depressive, eating, post-traumatic stress, and personality disorders).

In addition to my past clinical work experience, I have had various research, teaching, and supervision responsibilities. Specifically, I have published a peer-reviewed manuscript in Eating DisordersFor my PhD dissertation, I am examining how people can manage occupational stress proactively and adaptively and have presented my findings at a national research conference. I have coached graduate students in various cognitive behavioural therapy (CBT) certificate courses and provided CBT supervision to Master’s students at the University of Toronto.
