It would be impossible for me to mention all the groups or even put pictures of each of them, so I put some different ones. I have guided educational groups, Elder Hostel, EF, Explorica, several universities, photographers, ornithologists, etc.

I love it, because I learn a lot, even more than I can teach them.
    Currently I am not guiding groups with any company, I am working on personal projects, although I do not rule out going back to the playing field, I still feel very energetic.
