Jonah, Instructor

Hello, my name is Jonah Meyers! I am currently a junior student at Polk State Collegiate high  school, where I am currently taking college math courses such as statistics and pre-Calculus.  Along with this I am progressing toward an associate's degree in chemistry at Polk State and plan  pursue premed in college to eventually become a surgeon. Through my entire educational  journey so far, I have learned to enjoy math and its real-world applications. I look forward to  helping your student to help better understand math and help them make sense of the  complexities of it.



 Andrew, Instructor   

Hello! My name is Andrew! I am a senior at George Jenkins Highschool, where I am one of the Co-Presidents of the Math Club. My love for math has grown in various classes, such as AP Physics and AP Calculus AB, and continues to grow in AP Calculus BC and AP Statistics. My passion for the subject has moved me to pursue a degree in Engineering Physics at Florida Polytechnic. I look forward to instructing your child and setting them on a path to love and understand math!                                                     

Gabrielle, Instructor

   Hi! My name is Gabi Risko, and I’m currently a junior in the Biology program at Florida Southern College. In high school, I scored a 5 on every AP test I took, including AP Calculus AB and AP Statistics. Along with my job here at Mathnasium, I also hold positions at FSC as a TA, animal care technician, and writing tutor. I am also an honors student, and I am involved in a research project involving primates. My main love in life is science, but I recognize math as a necessary building block for Biology and other STEM degrees. I hope to help students become more competent and comfortable with math in order to achieve their goals, even if the goals aren’t directly math-related.
