Hello y'all. I am a one of the Sistem Tutoring tutors. I love tutoring, specifically middle school to college level Biology, Chemistry, and 9th grade Algebra. I've been tutoring since 2018 whenever I have some time between my school projects. At the moment I am in medical school at the University of Texas Rio Grande Valley so that I can be a doctor in about 2 years. Before this, I graduated with my bachelor's in Public Relations from the University of Texas at Austin. This year I have more time than normal, so I am taking advantage to have fun and tutor more students! I hope to see y'all soon in my class, and if you need me to tutor you in Spanish I can tutor all my subjects in Spanish as well.

I am a trained Musician, Martial Artist, and STEM Educator. I have a bachelor's degree in:
- Major: Music Performance
- Concentration: Education
- Minor: STEM
- Concentration: Calculus and Physics
With my diverse upbringing, I try to create at least 3 different ways of teaching the same topic; Intuitvely, Analytically, and/or Visually. If a student still does not understand the material, I dissect their preferred learning style and build the lesson on the student's foundation. This can take from minutes to entire sessions (depending on the student) to figure out but, I WILL figure them out nonetheless.
I pride myself on availability. If a student needs to ask a simple question, I prefer to have them (or their guardian) text and/or email me directly as to increase efficiency and ease for everyone.
I look forward to helping you!
