T.R.E.E.S. is a small owner-managed organization that prides itself on establishing close interpersonal relationships with its clients and the surrounding local community. Because we only have a handful of staff at the Hosting Center, our services are personalized and we offer our guests a feeling of being “at home”. Our on-site managers are professional biologists themselves and their familiarity with the local flora and fauna allow for a high quality learning experience. Their passion for biology is contagious and they have passed this on to the local staff, enhancing the experience for anyone engaging in biological studies at the center. Furthermore, because of the accessible location and proximity to a small village, we engage with our local community and allow guests to be immersed so that they can get a real taste of Central American culture. Everyone who has visited our center attests to the fact that the T.R.E.E.S team works hard together to make sure guests are always comfortable, happy, and experiencing Maya Mountain biodiversity first-hand.
