At first I thought picking a shop to get certified with would be difficult but once I talked to the guys at Virginia Scuba I was completely at ease. They have the longest list of certifications of any shop I've seen including shops on the ocean. They are the teachers of the teachers. I got my open water certification at the haymarket quarry this summer and they left me feeling confident to tackle Cozumel this winter. Not only do I recommend VaScuba, I literally trust my life with them.
