Terry Nooner (Owner) has a PhD in physiology for starters. 4 of us took a beginner course from him 29 years ago. We referred four other couples to him and two of those people were poor swimmers and frightened by the idea! He was so kind, reassuring and patient with them that they had no trouble certifying and are now avid divers. We've all been on multiple trips with him and his crew (organized by his shop) and everyone has nothing but great things to say about Terry and the arrangements made for the trips. He's honest, caring, helpful, knowledgeable, fun and funny. Everyone that I've met that works for him is cut from the same cloth. I've talked with lots of divers who've used other shops and instructors and I've heard a lot of complaints! Not so for St Croix Scuba. No matter where you live in the Minneapolis/St Paul metropolitan area, it's a short trip across the river to Hudson WI and well worth the drive. Do yourself a favor and go see Terry!
