PADI Course Director Gwen Grellier

He teaches the PADI IDC (Instructor Course) in English and French. He has a passion for instructing divers and has a lot of experience to share.

Gwen is from Britany, France. He has started his professional career 12 years ago in Greece, where he completed his Divemaster internship. He then traveled to Corsica, France to become an Instructor. In order to expand his experience and grow his career, he decided to learn more about cave diving and went to Mexico to become Full Cave Diver. He has been exploring the underwater world in Spain, Vietnam, Dominican Republic, France, Thailand, Belgium, Mexico, Canary Islands, Croatia, and across the United States... he has taught hundreds of courses in the process.

“To be part of the Dive Professional Community is something! Some days you teach or guide on the boat, some you are helping customers in the shop. Each day is something different and exciting."

Today Gwen is a Course Director working for the best 5 Star IDC Dive Center in Central Florida. Gwen believes that working at Seminole Scuba has such an enriching opportunity.  It has been opportunity for him to share his passion for the profession and pass that on to divers eager to become dive professionals.

The education at Seminole Scuba is unparalleled. We offer training in several languages, with a vast amount of experience to share with our candidates. To become a PADI Divemaster or Instructor is a big step in a diver's development and there is no doubt that at Seminole Scuba we make sure each step is being done in the proper way.

There are dive professionals trained by Seminole Scuba working across the globe. We know that our passion and reach is extensive and take such pride in knowing the untold numbers of divers enjoying the underwater world started right here, in Lake Mary, Florida.

I've just completed my Divemaster and IDC with Gwen at Seminole Scuba. 
When you complete your training with Gwen you are not only a much better diver for it, but you are truly prepared to teach the ART of Scuba. He was relentless in instilling real world teaching and techniques. He did not approach the IDC as a way to pass the IE, but rather the fine details of what it takes to instruct new and developing student divers. He pushed me to be better, never letting “good enough” be enough. As an administrator in public education, one of the things that stands out for me in working with Gwen, is that he is also a student.  He imparts his vast knowledge of diving, but still continues his own growth. During one of my workshops he complemented by presentation and said he learned a new strategy from me. This is what it takes to be a leader, a knowledgeable and yet growth oriented individual with a passion for his craft.

IDC July 2020 + MSDT Prep
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.

DM July 2020 and inspiring for ICD.
Gwen was fantastic, patient, fun approachable and at the same time  he wants to make sure that you learn, he is not going to let you pass just because. Gwen took his time to go over what ever I felt unsure about. He tried different techniques to help me to succeed, feel confident and trust myself and the knowledge that I just stuffed in my brain. I personally deeply dislike exams, specially the written ones. But Gwen inspired me in a way that one afternoon after our practice dive I went  straight for it without my usual nervousness and I passed with flying colors. I truly hope that I would be able to do my ICD preparation with Gwen, and I recommend hem to anyone who wishes to grow in scuba. Thank you Gwen
