Costanza's Philosophy

“I have a purpose behind my coaching to always stay on a growth trajectory.”

“All my students matter to me. They are important to me.”

“Team work begins with trust, confidence and feeling safe.”

“The player must become the primary problem solver.”

“I believe in meaningful work, intense concentration without distraction, and self-discipline. You must practice intensely to play intensely.”

“I also believe that getting lost sometimes is good.”

“No matter what it is, people play differently when they’re keeping score.”
