"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.  The blue hole is magnificent  The beauty of the island is unspoiled, the locals are open and genuinely friendly .  Can't wait to return for another class!"

"Once again, many thanks for your help, guidance and patience.  It was a great experience.  I also can't thank you and Tiziana enough for your hospitality."

"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."

"I was a bit apprehensive at first when my girlfriend said she wanted to go freediving in the Bahamas. After visiting your Vertical Blue website and reading your bio, I became intrigued. I figured worst case we would have a relaxing vacation on Long Island in the Bahamas (wherever that was). It turned out much better due to your patience and ability to work at our level."

"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."
