Allsmiles by Sarah St. John, RDHAP LLC is a mission-driven mobile dental hygiene practice founded in 2019 by Sarah St. John, a licensed Registered Dental Hygienist in Alternative Practice (RDHAP). Born from a deep commitment to health equity, Allsmiles was created to serve individuals who are often overlooked in traditional dental care systems — including seniors, individuals with disabilities, those experiencing homelessness, and children in underserved communities.
As Sarah worked one-on-one with patients in mobile and home-based settings, the need for a broader, community-based solution became undeniable. Families, schools, shelters, and care facilities consistently expressed one shared concern: “We know oral health matters — but access just isn’t there.” In response to that gap, Project Allsmiles Inc., a 501(c)(3) nonprofit, was born.
Today, the LLC serves as the service arm that powers and supports the nonprofit's mission. Our clinical team, equipment, and mobile infrastructure originate from the LLC — but our reach and impact are magnified through the nonprofit’s community programs. Together, we operate with a simple, yet powerful belief:
No one should suffer from preventable dental disease because of where they live, what they earn, or the barriers they face.
By combining a private practice model with a nonprofit mission, we’ve created a sustainable, scalable approach to delivering preventive care directly to those who need it most. We’re not just cleaning teeth — we’re building bridges to health, dignity, and opportunity… one smile at a time.
