About Us

We are here to support you on your journey to healing and wellness.

Triello Counselling Services provides direct psychotherapy and counselling to individuals with diverse mental health needs. We create an accessible space where individuals can access mental health services to achieve inner healing and discover their authentic selves. Our practice is exclusively virtual so that we can offer services to anyone across Ontario. 

 

We strive to maintain a client-centred and non-judgmental approach to helping individuals regain control in their lives and grow towards discovering their true selves and finding balance. We are true believers that therapy is not one-size-fits-all, that's why we take an integrative approach to mental health that utilizes evidence-based treatment modalities and prioritizes the needs of our clients.

 

Our team of therapists have experience and are compassionate psychotherapists dedicated to helping you on your journey of healing and discovery. Get in touch with us today to schedule your complimentary 15-minute phone consultation to see how our services help you.

Our Story

Triello Counselling Services was developed in 2020 with the vision of creating an accessible space where individuals can access mental health services to achieve healing, self-discovery, growth and wellness. 

  

Cassandra Tenneriello the founder of Triello Counselling Services had the opportunity to provide counselling services throughout the remote, isolated Indigenous communities of the James and Hudson Bay region. This experience has helped Cassandra better understand the importance of the interconnection of our physical, emotional, spiritual and mental wellbeing. In addition, Cassandra's time in Northern Ontario allowed her to gain insight into the barriers people living in remote communities face when trying to access mental health services.  This is why Triello Counselling Services provides exclusively virtual services to ensure accessibility to all Ontario residents.
