"We relied on Kevin (well known taxi driver) to get us to the best ferry to still make it to Tortola that day. We prearranged to have him meet us. The last known number I have for him is 340-643-0025. I’m sure others here can chime in on whether he’s still around."

Yes that is his number, just saw him a couple weeks ago. I've always used his service.
I have found its good practice on every island we visit to try and use the same driver. It cuts out the fear of getting gouged or worse.
