About Us

Little Medical School Wexford

Little Medical School (LMS) is deeply rooted in Founder Dr. Mary Mason’s love of family, medicine and education. In 1998, Dr. Mason wrote her first lesson plan and enlisted her medical residents to teach local teenagers. This passion for encouraging careers in healthcare culminated in the creation of LMS in 2010. Today, the company is a pioneer and leading developer of specialized curriculum and interactive resources for children aged 1-14.

We offer kids camps, after school classes, school tours, birthday parties, scout badge classes and special events that we can customize to fit your needs.


Imagination: We believe children need to dream and have opportunities to discover.

Nurturing: We create environments to learn and explore while building self-confidence.

Service: We realize love of medicine requires a commitment to helping others.

Passion: We are energized by our desire to share our love of learning and health.

Innovation: We engage all by merging entertainment and education.

Role-playing: We realize the power of one-on-one AND group interaction.

Educational: We develop unique curriculum to highlight career options.

While all seven values above form the foundation of why we exist and how we conduct business, our most important function is to INSPIRE a greater understanding of health and career options.
