I've taken Stacey's cardio tennis class for 10+ years and I recommend both the class and Stacey as an instructor. The class is 90 min. of drills and skills practice and fun games to keep things interesting. She even gives healthy snack packs to the "winner." of each competition. She will give you suggestions on ways to improve your shots but she won't say "do this, do that." or " You're doing it wrong". I've taken classes with many instructors over the year and I keep coming back to Stacey's classes.
