Jana Zollner


Jana Zollner started playing tennis at the age of 5 and started coaching in 2018. She played high school tennis Sophomore-Senior year and was the finalist in 2018 and the champion in 2019.

Jana became a certified PTR coach in April of last year and thanks the PTR Foundation for awarding her a scholarship for the Level 1 Certification course.

I’m excited to see what the future holds to be able to work with the PTR Foundation as a social media influencer!

Donating percent of his stringing services to the foundation – I own a small business, City Racquet Shop, located in San Francisco, CA. Tennis has been a passion of mine since 2007. I love learning the different factors that go into how a person can perceive a tennis racquet and figuring how I can personalize the racquet for that person. It is deeply moving to hear that the PTRF helps provide tennis for the under-resourced community, the special populations, grants, and many other individuals and organizations. I do hope my contributions help the foundations to further tennis for all. I do feel that when giving and helping others, the energy and karma will be looped around from one form to another.
