Smile Outreach International

Our Story

Smile Outreach International was born out of the founder, Dr. Mark Costes’ passion to utilize his skillset and those of his professional colleagues, to alleviate some of the pain and suffering that billions of people endure due to untreated dental disease.

In fact, according to the World Health Organization, it is estimated that 3.5 billion people worldwide are affected due to the lack of access to dental care. Smile Outreach International will provide dental surgeries and services to underserved populations throughout the third-world several times per year on an annual basis. The mission will be designed on a first come first serve basis for each project. These services are provided through a network of incredible volunteer licensed professionals and additional support teams.

The organization is funded through various methods, including individual donations, corporate donations, mission sponsors, and fundraising events. The money we raise goes directly to dental supplies, equipment, facilities, and mission logistics for all services and projects!

Our Core Values

Compassion: We deeply care about the pain and suffering caused by untreated dental concerns and we want to help those in need.
Collaboration: We rely on a network of volunteer licensed professionals and sponsors to provide dental care and recognize the power of teamwork and coming together.
Access: We believe that access to dental care is a basic human right and are committed to making it available to those who can’t readily access care around the world.
Transparency: We are open and accountable in all our activities and operations, including fundraising, finances, and mission projects.
Impact: We strive to make a lasting impact on the communities we serve by providing effective and efficient dental care services.

We’re always looking for new volunteers and supporters who share our values and want to help make a difference in the world. Please feel free to reach out if you’re interested in learning more about our organization or getting involved!

Our Vision

Our vision is to build a sustainable and scalable model for providing dental care to underserved populations, one that can be replicated and expanded to reach even more people in need.
