Scuba Educators International (SEI) was formed when the YMCA decided to sunset its YScuba program after 50 years of service. SEI continues this tradition of excellence and quality in providing knowledge and skill-based courses for scuba divers.

SEI is international in scope with instructors in many US states and in numerous countries around the world with corporate offices located in Muncie, Indiana, USA.

SEI is poised to continue growing into a strong, innovative, and dynamic international scuba education program.
