I had a 5 star diving experience with Alexey. As a first time diver I was a bit nervous, however He was incredibly knowledgable and professional which helped put me at ease. He has over 20 years experience and nearly 1000 dives. During the entire class he explained everything, answered all questions and was very patient. He helped me learn to be comfortable with the equipment and get used to breathing under the water. At times I would get nervous and he never pressured me or my Husband to go beyond what we felt comfortable doing. We ended up doing 2 dives 45 minutes each! We loved the entire experience and saw many beautiful sea creatures & typography ! While at the Cenote I did observe other instructors and many were not so patient. We are extremely happy with Dive Guru and hands down recommend them to anyone considering scuba. If you are nervous and want someone that takes safety seriously and will go at your pace this is the place for you. They love scuba and will help you love it too!
