If you are looking for an SSI Scuba Instructor and SSI Scuba Certifications, consider an equivalent or advanced SDI (Scuba Divers International) / TDI (Technical Divers International) scuba certification.
Urban Manta NYC scuba shop owner Sandra Clopp has previously been an SSI instructor with Village Divers in New York City. Now she trains divers in beginner scuba, advanced scuba, and specialty scuba with SDI scuba courses and TDI scuba courses.
After Village Divers retired, Sandra sailed to new frontiers and launched the more advanced technical training for SDI scuba classes / TDI scuba classes.
