Jeffrey Seckendorf Curriculum Vitae

Jeff learned to dive in 1990 in preparation for assisting with a series of underwater filmmaking workshops in the Caribbean. He went on to dive extensively in the warm waters around the Virgin Islands and the [very] cold waters of upstate New York lakes. After a long career in the film industry, Jeff co-founded Unified Team Diving, a global Scuba training and certification agency and Scuba equipment manufacturer. In 2020 Jeff purchased the training company outright, renamed it UTD Scuba Diving, LLC, and separated it from the equipment company.

Jeff has traveled the world as a diver: Egypt, Spain, Italy, France, Mexico, Dubai, the Caribbean, and domestically in all four corners of the country. He’s been in the caves in Mexico, Florida, and Europe, is trained on the MX-Series of rebreathers, and is a UTD Instructor Trainer.

Jeff has been teaching adults all his life. He spent two decades on the faculty of the International Film and TV Workshops and the Rockport College and eight years as the owner of One On One Film Training, a mentoring/consulting company working with emerging film directors. Jeff is a Certificated Flight Instructor and spent many years teaching and competing in competition aerobatics.
