I like Coby. He is good at coaching both beginners and intermediate players. What I like him the most is he helped us build a modern tennis framework without overly fixating on little details. We are making progress while having fun.

My husband and I took Coby’s tennis class. We were all zero experience beginners. And Coby is being patient and instructive. Nice classes
