About

At GEG, we serve people who work long, unusual, or unpredictable hours. We help companies where fatigue and caffeine use are the norm. Through our workshops and consulting, we teach people what to drink and how to think for every Level of Fatigue. This ensures that when fatigue does happen, it’s less likely to hurt the employee or those they serve.


GEG founder Danielle Robertson Rath (the “GreenEyedGuide”) has nearly 20 years experience researching caffeine and energy drinks, plus 10 years experience in Risk Management across multiple industries including Food/Bev, Supplements, Manufacturing, and IT Consulting.

What We Do

At GreenEyedGuide, our goal is to help people who work long, unusual, or unpredictable hours know what to drink and how to think for every Level of Fatigue.

Here’s how we do that:

1) Empower those in Health Services with the latest research on caffeine and energy drinks
2) Educate caffeine consumers on how to maximize caffeine’s benefits while minimizing its side-effects
3) Enable companies to manage fatigue in the workplace, from boredom to burnout and everything in between
