Meet Josie

Josie Costantiello is an Independent 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, her mission is to break down barriers to obtaining preventative 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.  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 Kerry’s Place, Community Living Toronto, Reena, Christian Horizons, Montage Support, Several Mental Health group homes, Addiction Recovery Programs and has opened doors to many individuals who require in-home/on-site customized dental preventative care. Josie alongside her Dentist partner, facilitates referrals to dental clinics within the community or hospital setting for further dental treatment outside of dental preventative care.  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.

Complex Needs - Josie is experienced in providing preventative dental care for persons with complex needs such as  Progressive Multiple Sclerosis, Cerebral Palsy, G-Tube,  Tracheostomy.  All case acceptance based on current and past medical history review, as well as medical clearance by physician(s) when deemed necessary.

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
