Yes, I have been to Saviano's several times and have trained my daughter on the courts right next to the courts Kriek uses for the last 6 months. So I peek over and get lots of knowledge!!
Johan Kriek runs a very family like program, all the kids are very close. They work hard, mostly on Har Tru, sometimes on hard courts. The academy is relatively new and growing, the staff is getting better and better. Great people and a great area on the Gulf Coast.
Saviano is an amazing teacher, very personable and connects with the kids. He has put out some very talented players. The location is on the east coast, in Sunrise Fl.
Honestly, flip a coin because both Kriek and Saviano are top notch teachers and even better men. You can not go wrong at either location. I would say that as of this moment, Saviano has a little better caliber group of players than Kriek.
