"I cannot say enough wonderful things about this company. Honestly, Dervin (the owner of the company) and his group of drivers and tour guides were the best part about our trip to Costa Rica. They were very knowledgeable about the area, and very professional, but also super friendly and fun. They all went out of their way to make sure that we were taken care of , safe, and that we were happy with our experiences. I will absolutely use Yellowfin every time I visit Costa Rica. Thank you !!"

"My family of four, along with my sister and her family and our parents stayed at the Villa Corazon del Mar this summer for a week. We were greeted at the airport by Greavam. He and Pepe brought all twelve of us to eat and to the grocery store prior to getting to the villa. Each day Greavam or Dervin was with us or organizing our activities. Some things that we did include horseback riding, Lazy Lizard catamaran and snorkeling, jet ski rentals, watching sea turtles lay eggs in Playa Ostional, and the canopy tours/ mud bath/ and hot springs in Rincon de la Vieja. We even ate supper with Drevin, his wife, Anna, and children (Daniel, Allen, and Catalina) and Greavam on our way back from watching the Ridley sea turtles laying eggs....which only happens four days twice a year. This shows that the reviews are "spot on" when it reads that these guys treat you like family. Both men taught all of my family things that we will always remember. We were all truly impressed with Yellowfin Sporting Charters services, but more importantly with the hospitality that these wonderful people have shared with us!!!"

"I had an amazing trip to Costa Rica and owe a big thank you to Dervin for the experience! Dervin was very accommodating of our large group and very knowledgable about the country. He answered all our questions and was very informative! He took us to local hang outs off the beaten track so we could experience the real Costa Rica! He took us out on a catamaran and even brought us fresh shrimp because we had request it. He takes the time to get to know his clients and customizes trips for you! I can't say enough good things about Dervin and Yellowfin Sportfishing! Choose Dervin next time you are in Costa Rica, You will not be disappointed!"

"Thanks to my dad and friends, I've been dealing with Mr. Dervin ever since I went to Costa Rica for the first time! I'm 18 and have known him for about 7 years and nothing I could say about him could match up to how truly amazing he really is! Such a genuine guy, and the service he provides is ABSOLUTELY AMAZING. You're basically royalty with Mr. Dervin! He's very adventurous and any activity we encounter he takes care of us always. He recently set up a very important project for my school in Maryland and I've had nothing but outrageous results. Mr. Dervin's the man to go to; I wouldn't chose another tour guide or staff for anything else! I just got back from vacation, (with Dervin tagging along thank goodness), and another amazing vacation came out of it! Mr. Dervin is your go to man! You won't regret it!"
