"coach Marvin is the definition of salt of the earth. He is always busy but will always stop to talk, catch up or help. He is kind and patient but passionate and is able to motivate others because of his passion. He speaks quietly but carries a big stick, but a nice one:)"

"I've been using Marvin's dive shop, Sea Sport Divers, for at least 15 years - for tank rentals, boat dives, and equipment repair, and I can't say enough good about the service I've received, so he's hiring good people and training them well. Marvin himself is the master of repair - I trust him completely with equipment that my life depends on."
