Pros
I have worked at various universities and in consulting, but the best people with whom I have worked in my career have been at Osa Conservation. They are people of strong character and integrity who are committed to doing positive, science-driven, conservation-oriented work in Costa Rica and more broadly throughout Latin America. Osa also hires many Costa Ricans and has a strong record of building and sustaining conservation partnerships with local landowners and farmers in Costa Rica. They have an incredible field station and conservation campus on the Osa Peninsula in Costa Rica. The Osa Peninsula is one of the wildest places left on Earth and experiencing the unique ecosystems and wildlife inspired me to continue working in conservation for the rest of my life/career. Although I was a remote employee based in the US, they paid for my flight from the US and room/board for me and my wife for a few days on their campus. I also had an excellent interview - the people on the other end were well prepared with thoughtful questions and it was clear they had actually read my application and looked at my resume. As a prospective employee, they treated me like a real person worthy of respect. That's saying a lot these days!
Cons
Small organization with limited resources; Osa should not be compared to large international conservation nonprofits
