on the Master Class...
"The Vertical Blue master class program offers exactly what it advertises: individualized instruction to the student's level of ability. The program offers the best and well-rounded freedive instruction with the highest caliber instructors you can find anywhere to date."
"This course gives the student the complete program they need to become a better diver with yoga, mental training, technique, diet, and training plans. That is what I was looking for; I wanted a plan and I got that and so much more. I now know what I can do everyday to enhance my performance with physical and mental exercises. The instructors were exceptional and it was a privilege to receive such valuable advice and support offered with a patient and a positive attitude. I would recommend this course to anyone who seriously wants to become a better freediver because I believe it offers the best results."

on the Stage...
"Would just like to chime in and say that I had the privilege of training with William for one of his freediving courses. I can wholeheartedly recommend his course and really can't say enough about how educational, relaxing and fun the experience was. The location is beautiful and the diving site is completely unique. From yoga, to theory, to plunging into the abyss, it's just plain fun."
"William is a champion that has elevated to a superhuman level. To attain his feats of freediving he has trained both his body and mind - and he shows you how, selflessly noting where his ideas differs from others in the sport. His spirit and focus is contagious.
"We did the stage course with Vertical Blue and it was a fantastic learning experience! Everyone received plenty of individual in water instruction, which was very much tailored to each student's ability. The instruction itself was very clear and everyone improved in leaps and bounds! The theory component was really interesting. We learned not just the "what" but the "why" - which gave us a much deeper understanding of the physiology and practice of freediving. The theory was always very clear and presented in a logical fashion. This is definitely the course for people who want to gain a deeper understanding of the theory and practice of freediving. We were really pleased with the depth we achieved during the course and we feel much more confident in ourselves now to practice safely, effectively and to continue to reach new depths."

on the Introductory class...
"The intro to freedive class at Vertical Blue was beyond my expectations. William is a skilled, complex, personable and patient instructor. The class was tailored to each individual skills and abilities and each of us got personal attention. Just watching William dive was a privilege. The sun rays filtering thru the deep blue of the water gave me a sense of peace never experienced before. Can't wait to return for another class!"
"I just wanted to send you a quick e-mail to tell you thank you for the class. It was a lot better than I had hoped. It really opened my eyes and was one of the best things that I've done. I don't plan on shattering any records any time soon, but I do plan on training further."
"The course was very organized and both the practical and classroom sessions were structured well for beginners. It was amazing to me how much just a few simple breathing elements and relaxation techniques helped us improve. I was surprised by how much mental strength is required for the Apnea exercises. The classroom sessions were very well presented and you explained everything very well."
