    Greg stands out as the star of this operation, earning consistent praise as a patient, knowledgeable instructor who excels at making nervous first-timers feel completely at ease. Reviewers highlight how he balances thorough safety training with fun, gives individual attention even to larger groups, and has a genuine passion for sharing underwater experiences. His team members, including Jen, Dray, Tony, and Captain Joe, also receive specific kudos for their teaching abilities and attentiveness. The setup works particularly well for beginners and families. Multiple groups mention bringing kids as young as 11, and parents appreciate the intimate boat size that doesn't feel chaotic or overcrowded. The Hawaii Kai location offers convenient free parking and nearby restaurants, plus relatively short trips to quality dive sites where guests regularly spot turtles, octopus, sharks, and abundant marine life. The photo packages are mentioned as worthwhile additions, capturing memories without you having to worry about equipment. Several reviewers specifically note this is their new benchmark for dive operations and have returned for repeat visits.

    Went with a group of 5 to Oahu for our open water scuba certification and we had a great time with Greg and team! It was our first certification experience (and first multi-tank dives) and we felt really supported with plenty of individual attention despite our group size. Greg was very patient and willing to be flexible with timing when our pre-dive training went a little over time and the boat charter had to be pushed back some. Captain Joe and Greg were very supportive and caring when members of our group experienced seasickness and needed assistance. Greg kept a balance between the practical training and having fun, so every dive was super enjoyable! We had great value and came out feeling prepared and excited for future dives
