Covid-19 Update

Covid 19

The well-being of our clients and clinicians is our top priority.  Due to the ongoing health risks associated with the Covid-19 pandemic, all counseling, parenting, and social-skills services will continue to be provided via telehealth (phone and video) sessions only. Our online platforms are secure and PHIPA-compliant, and telehealth services have been found to be an effective alternative to in-person sessions. We are committed to supporting the mental health of our clients through these challenging times. Please phone or email to book a telehealth session.
