He loves the great change of pace and atmosphere at LPTA and leverages his hospitality experience to make sure the member experience and grounds are top notch. When he's not at the courts, he's hitting the links or shredding some gnar on the slopes in Utah.

Duncan Stephens
Grounds Manager
Duncan has been at the club since 2002. Everyone knows Duncan! He’s responsible for the upkeep, maintenance and improvements of the courts & grounds for both LPTA and DTC. Duncan rises before the sun, and you’ll often find him at the club as early as 4:30 am. Fun Fact: Duncan is an excellent cricket and rugby player and played semi-pro soccer in the 70’s and 80’s.

Tom Dean
Staff
Tom began with the LPTA team in the summer of 2020. He started hitting the ball when he was ~13 years old because "it was the only thing to do at night” (the court had lights!) in his hometown of Bourbonnais, IL. When the days got too hot, he’d watch tennis on TV, expanding his love of the game. When not at the courts, Tom can be found at his other job as a doggy daycare attendant or creating/vending his abstract artwork. He loves to travel and has lived all over. At LPTA, you'll find Tom listening to music and befriending the birds and squirrels!
