Analee Delgado

Tennis professional - PTR Certified 10 & Under, usta tournament director

better size.png

Talent & work ethic earned Analee multiple scholarships to train at tennis academies as a junior, but from age 13 she realized her dream was to coach.

Her life-long passion for the sport is contagious.

As a toddler, she accompanied her father to the courts, where she watched him take lessons. From the sidelines, the interested four-year old would trace the shape of whatever stroke he was learning. Shortly thereafter she was enrolled in classes of her own.  

Many junior players aspire to beat a rival, or win a trophy, but to understand coaching principles from such an early age has been a huge advantage in her teaching career. 

Analee has been coaching since playing for St. Peter's University (five years ago). Analee has a great eye for developing sound strokes & recognizing what her students need to focus on, all while making tennis fun.

She lives in Bellville, NJ.
