Decision is yours to make....
Very few kids are talented, for the rest is up to the instructors and the school. At TessaTennis my kids had over 7 jr. lv 1 instructors in almost three years of training there and no strategy in training. Parent's complain of the instructors luck of experience went in vain. I have moved my kids recently, after being advised by many parents, and I am very happy with the new place. At this new location they have very experienced intl. coaches and they are exposed to local&intl. tournaments. GL.
