Gwen is really determined, disciplined yet patient when it comes to teaching. With his thorough teaching, I was prepared to overcome any problem. He breaks down harder questions into simple analogies that will stick in your head for a long time. Concepts became way simpler. One particular thing that helped me during the Instructor Exam is basically “What would Gwen do to teach and solve this skill?” I put myself in his shoes and try to think like him. The outcome, I’m a PADI Open Water Scuba Instructor as of today.

I would like to say that having you as an instructor for my MSDT course was an amazing experience. Your skills and knowledge are exemplary. You made me feel very comfortable giving my dive briefings, and gave me many suggestions on how to keep them organized. You also made it fun for me. If I ever come across anyone who wants more training I will absolutely send them your way. I will be returning for more training with you as soon as i can. I give you 5 stars. Thank you for all you taught me. Dive on !

My IDC was in April 2019 From start to finish Gwen help me the whole entire IDC. I had issues with certain parts of the written exam, Gwen never stopped helping. Until I was confident enough and had the right knowledge to pass that part of the exam. also he had spent a lot of time prepared me for being an instructor and making sure all my underwater skills were perfect. I very much enjoyed my IDC and would highly recommend using Gwen for there IDC, last I would like to thank Gwen for all he did.
