Hi! I'm Gabrielle. In high school, I was a high achieving student. I earned the title of valedictorian and was awarded a National Merit Scholarship. This gave me access to a full ride at the University of Florida, where I fell in love with science and became a Chemical Engineer. I have spent 3 years as a pharmaceutical engineer and recently scored a 99% MCAT, earning me a spot in the USF Morsani College of Medicine Class of 2030. One of the reasons that I love tutoring is that I experienced the hardship of trying to learn STEM material. I am not a naturally gifted student - it was only through working with others, practicing, and talking through the subjects that I was able to succeed. I have put in the effort to get where I am and know that, with the same dedication, you can succeed in your studies as well! I hope to share the lessons I've learned as a scientist. If you think we would align, don't hesitate to schedule a session. I look forward to meeting you soon!
