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.

June 2, 2020:

COMDH COVID -19 IPAC enhanced measures to prevent the spread have been implemented.  The full document can be emailed to you at your request.

In addition, the Ontario Ministry of Health is recommending In Home Care as a "modification" in receiving dental care as an alternative to a clinic setting. In Home Care is being considered a safer approach in preventing the spread.

Check out the article featured in Oral Hygiene Magazine where our Dental Hygienist Josie advocates for mobile dental clinics and changes to government funded dental programs.

November 30th, 2017:


Josie Costantiello along with 3 other health care providers spoke about their collaboration in treating someone with complex health issues and developmental disability, in the safety of their own home at the Health and Wellbeing in Developmental Disabilities, a conference by the University of Toronto. What do 4 health care providers, one a Registered Nurse who facilitates medical and dental care, a Behavioural Therapist with Surrey Place, a Nurse working at a Diabetes clinic and a Registered Dental Hygienist have in common? Their compassion for others and their need to break down barriers to accessing much needed medical and dental care, even when someone refuses to leave their home.

We take the time to get to know you, your child or client(s) even BEFORE meeting you/them in person to achieve the best treatment experience

A detailed questionnaire will be provided for us to find out what you, your child's or client's "likes and dislikes" are, to be able to customize each appointment to achieve success with you, your child or client(s). For any behavioural, anxieties, non-verbal challenges, we use ABA techniques and create a calm atmosphere to aid in the receiving of our preventative dental treatment 

We will do what we can to take the time to make you, your child or client feel comfortable, so that more can be achieved at each future visit in the comfort of their own home
