Meet Josie

Josie Costantiello is a Self-Initiated Registered Dental Hygienist with a passion for treating persons with special needs including persons with Autism Spectrum Disorder (ASD), Mental Health Conditions, Developmental Delays and Dual Diagnosis, more importantly, breaking down barriers to obtaining preventive dental care within the community.  Josie's dental industry experience began in 2004, where she started her career at the Mount Sinai Hospital Dental Department, became Clinical Director with the Special Olympics in 2015 and currently works as a Clinical Instructor in the Durham College Dental Hygiene clinic.  Josie received additional training from the Geneva Centre in Toronto, where she learned ABA (Applied Behavioural Analysis) techniques in a dental setting and gave her profound knowledge on how to cater each dental experience to meet the needs of persons with ASD or other various mental, neurological and/or behavioural challenges.  Josie has formed relationships with different organizations such as Surrey Place, Kerry’s Place, Geneva Centre, Community Living, Reena, Griffin Centre, Christian Horizons, Montage Support, Several Mental Health group homes, Addiction Recovery Programs, Homeless Shelters, and has opened doors to many individuals who require in-home/on-site customized dental prevention. Josie facilitates referrals to dental clinics within the community or hospital setting for further dental treatment outside of dental prevention.  Josie has 3 family members with varying Special Needs and has made it her mandate to service those who are vulnerable and have had challenges obtaining dental care, in a compassionate and caring manner.

Opening Hours

Due to COVID -19 mandatory closures of all small businesses deemed non-essential by government officials, COMDH has been temporarily closed since March 16th, 2020 and continues to follow government updates on when small businesses will resume.  We hope to resume by the end of May 2020 based on government advisory and will continue to take all necessary precautions to ensure a continued safe and preventative approach to providing preventative dental care.  We are still available to help our patients navigate through any dental emergencies that arise during this pandemic shut down phase. Please call or email to contact us for any assistance.

We look forward to being able to serve our community based patients in the near future. Take care of yourselves and each other.
