finding frank

Hello everyone!
I was recently in the Dominican for a holiday and met somebody named Frank. We left on pretty bad terms and I want to apologize. All I know is that he lives in Puerto Plata and works in Sosua at a gym as a personal trainer. I have been trying since I got home to locate him but have had no luck. So if anybody knows of who I'm talking about or knows how I could find out PLEASE email me. Thank you so much! I hope to hear from someone soon!
