What has been your biggest tennis moment so far in your career?
“I have two biggest moments. One is when I won a Bolivian Open, where it is supposed to be the best tournament for Bolivia. I was playing the second-best player in Bolivia Mauricio Estivariz. So I think that was a big tournament for me since I never actually won a national tournament. My second moment was to accept to come to the University of Iowa since it is a really good program and it has a great academics.”
What are your plans following graduation?
“My plans after graduation is two work at least for two years in the USA in engineering. Hopefully, I can get a job in a big city or somewhere in the South since I have never lived there. After that I will have to take a decision between keep working, going to graduate school or going back home Bolivia.”
