Lessons
Every player starts somewhere different. Sessions are shaped around your level and how often you can get on court.
$80/hour
Or 5 lessons for $375, 10 for $700, paid in person.
One-on-one for juniors and adults alike. Stroke and serve mechanics, footwork, the slower, softer balls young beginners learn on, and a practice plan you can actually work on between sessions.
30-minute lessons
$45/30 minutes
One-on-one, focused on one part of your game.
$110/hour for two — $55 each
The same lesson, split between two players of a similar level. You each pay less than a private, and the pairing gives you live rallies and points to work through rather than feeding alone. Bring a friend, a sibling, or a doubles partner.
Bring a friend who's new to me and you both get $10 off your first semi-private lesson.
$45/hour
Straight hitting rather than instruction, for players who just want a reliable ball to work against. Sessions run 60 minutes or longer.
Per group, quoted by size
Small groups on one court, working through drills and live-ball games with enough rotation that everyone keeps hitting. Cost depends on how many of you there are.
Giving tennis as a present? Any private lesson, package or hitting session can be a gift.
About
I've been coaching for three years. I started as a Junior Pro at LifeSport Libertyville, then joined the Pro Staff of Grip N Rip, the junior program at Newport Beach Tennis Club.
I'm certified by the RSPA, the Racket Sports Professionals Association (formerly the USPTA), and approved under USTA Safe Play: background-checked and SafeSport-trained.
Most of my work is with developing juniors — getting the fundamentals right early so progress keeps compounding. I also run adult clinics for players who want more consistency and a clearer plan once points actually start.
I played four years of high school varsity. Coaching is a part-time job for me, fitted around school, so the schedule stays small and deliberate.
The court
Hover or tap a part of the court to see what we work on there.
Where most of the lesson lives. Groundstrokes, footwork and rally tolerance: ten balls in a row before you try to hit one hard.
Serves and returns. The toss and the rhythm come first, then the spin, and you serve at a target rather than just over the net.
Volleys and overheads. Short swings, early contact, and the footwork to get there in time.
The transition zone: approach shots and the half-volley, the shots that take you from the baseline to the net.
Doubles. Angles, poaching and where to stand, for anyone playing league or social doubles.

Reviews
I mentored Isaac at LifeSport Libertyville and watched his growth firsthand. His work ethic, self-discipline, and commitment to improvement led him from student to Junior Professional, where he coached Red Ball, Orange Ball, and high school match play with strong leadership and care for every player's development.
