I have been PADI certified for 22 years, and signed up for a "fun dive" at ATI divers. I was suprised at the professionalism of this outfit run by Andy. Even with my experience, Andy wanted to insure I was familiar with high altitude diving. I have been on too many dives where the dive masters do not care about... More

I feel a little bad not giving this place 4 or 5 stars like the other reviewers, but I just feel like it's giving the wrong impression. I took my husband to do the altitude specialty course with ATI partly due to the great reviews I'd read on Trip Advisor. And don't get me wrong - the company itself is... More

I went to Lake Atitlan both for its beauty and also because I was interested in trying out altitude diving just out of curiosity. A handful of people tried to persuade me otherwise, saying that there's nothing to see in the lake, that it's polluted etc. and basically saying it's not really worth diving at Atitlan. Despite all the discouragement,... More

I was on Lake Atitlan for a month while working for a medical aid program. During that time, I decided to take up scuba and saw that ATI divers was offering an Open Water course on the lake with flexible scheduling. My instructor, Andy Morgan was excellent. He made sure I was comfortable with all skills and allowed me to... More

I was very impressed with my experience with ATI divers. My instructor, Andy Morgan, was exceptionally professional and trustworthy. He tailored the class to my needs and skills, and addressed my concerns in such a way as to make me feel comfortable and at ease. The location at Lake Atitlan, Guatemala, is beautiful and provides for interesting dives, with reasonably... More

I was staying on Lake Atitilan looking for something different to do and found Andy and Ati Divers on line. I did a one day Altitude Diver Specialty with Andy and it turned out to be my favorite day in Guatemala. I learned a lot and was able to make two really unusual dives at altitude. Andy was an excellent... More

Lake Atitlan is a great place to learn scuba, as without all the distractions of not wanting to disturb coral or fish, you really concentrate on diving skills. Andy is an amazing teacher, patient, calm, humorous, intelligent, and focused on safety. I took this class to help get over my fear of drowning, and after I left, I went to... More

I spent five days at La Iguana Prdida. This was during a tropical storm and I still had a great time. The staff was so friendly and welcoming. The meals where scocialble and tasty. I took the ati diver cource and I don't regret it. Andy, the instructor, is great. He really knows his stuff. Even though the visibility was... More

During my time at (Beautiful!) Lake Atitlan, this spring (2010), I was fortunate enough to dive with Andy at least 7 times. After doing 1 fun dive with him in March, I had such a good time with him, I decided to get my advanced open water certificate with him. The price was right ~ Cheap! ~ and he is... More
