I had the awesome opportunity to take part on presential toxicology lessons with Guillermo. He has a way to teach in which information is fun, easily digested and quick to remember. Adding to that, he always made an effort to find specific scenarios regarding my major.

I received toxicology lessons from Guillermo when I was in my fourth year of medical school and I can say he’s definitely one of the best tutors that I have met in my academic life. His classes were dynamic and fun. He is attentive to his students’ needs and is always open for suggestions. I can’t recommend his teaching services enough. Don’t miss the chance to become a toxicology savvy with Guillermo!
