If you are a PADI Instructor, Dive Center or Resort, you must log in through the PADI Pros’ Site.

PADI Members are licensed to use various PADI Trademarks and to conduct PADI training. Individual, dive center and resort Members are not agents, employees or franchisees of PADI. Member business activities are independent, and are neither owned nor operated by PADI. While PADI establishes the standards for PADI diver training programs, it is not responsible for, nor does it have the right to control, the operation of the Members’ business activities and the day-to-day conduct of PADI programs and supervision of divers by the Members or their associated staff.
