Leena & Martyna are awesome freediving instructors that I have taught with so if I don't have what you are looking for reach out to them! @freediveohana.com
Javier Cantellops runs great dive boats and he's a lot of fun! He has two boats running scuba, snorkelling and freediving trips. I've been out on his freediving trips and they are great! @diveislandstyle.com
Maui Sporting Goods in Wailuku is a great place to get all of your freediving gear. I've bought a lot of gear there over the years and the prices are good and the equipment is durable. @https://www.mauisporting.com/Wailuku-store
