Do you want to join TNT's guide corps?

Does falling asleep to shooting stars or waking up with morning dew on the outside of your bivy sack bring a smile to your face? Do you practice mindfulness meditation and yoga? Have you ever taught it? Do you have your WFR and any experience leading groups in the outdoors? Any other special outdoor talents, certifications, or group leadership experiences? Have you ever worked with people affected by cancer? If you feel like you're a good fit to either be a mindfulness or wilderness guide and you're interested in learning more about joining our guide team, please send a note to Ms. Vanessa Hood, Lead of Trek Logistics and amazing human being extraordinaire: [email protected].
