Mery is an amazing instructor! She taught the whole course in perfect Spanish, and from day one, she made me feel safe, comfortable, and confident in the water. She was always patient, supportive, and made sure I was enjoying every step of the experience. You can really tell how passionate she is about diving, and that makes all the difference. Thanks to her, I didn’t just learn how to dive, I fell in love with it! I couldn’t have asked for a better instructor. Grazie di cuore, Mary! ❤️👌🏻🤙🏻
