I don't do any certifications as I'm not Instructor rated.
Two great shops with Instructors on the Lake though!
Central NH Divers in Meredith just past Funspot on your right (soon to be closer in Laconia/ Old Burgerking site) and Dive Winnipesaukee in Wolfboro.
Tell them I sent you please!!!
I can take you out for your 4 checkout dives (After classroom & Pool work), sightseeing, weddings, private charters, etc, etc, etc,
