Welcome to Triello Counselling Services

My integrated educational and career journey in the field of mental health has spanned 20 years and I have been registered as a psychotherapist with the College of Registered Psychotherapists of Ontario since 2016. Prior to entering private practice, I maintained a long-standing career with an accredited social services agency supporting children, adolescents, parents, and families to achieve greater mental wellness. I have also held positions providing clinical services in both inpatient and outpatient healthcare settings.


I possess particular knowledge and experience in infant, child, and adolescent mental health and development. I am passionate about enhancing mental wellness by providing children, youth, parents, and families with support and strategies to maintain optimal family functioning and parent-child relationships. I have gained extensive experience treating anxiety and related disorders, emotion regulation challenges, depression, OCD, self-esteem concerns, ADHD, relationship difficulties, self-harming behaviour and traumatic stress.


My practice is informed by attachment, development, and trauma-based approaches. My training and experience comprises the frameworks of Cognitive Behavioural Therapy, Dialectical Behaviour Therapy, Interpersonal Therapy, and Child-Parent Psychotherapy. I have also gained specialized training in Trauma-Focused Cognitive Behavioural Therapy as well as Perinatal mood and anxiety disorders.


I strive to pay special attention to the nourishment of the therapeutic relationship by demonstrating a warm, compassionate demeanour. I utilize a collaborative, strengths-based approach that is tailored to fit with the desired outcomes of the individual and geared toward helping individuals discover and honour their own strengths and abilities in the midst of obstacles.

My Specialities Include:

  • Infant, Child, and Adolescent Mental Health and Development

  • Family Counselling

  • Relationship Difficulties

  • Stress & Anxiety

  • Depression
