An apparatus comprises an elongated body comprising a top end, a bottom end, a chamber extending away from the bottom end, a hole extending through the bottom end into the chamber, and a door to expose the chamber and an interior of the hole. The chamber retains a golf tee with the door in a closed position. The hole enables only a bottom portion of the golf tee to extend beyond the bottom end. An adjustment mechanism adjusts a depth of the chamber to position the golf tee to protrude a desired length out of the hole during placement of the golf tee into a tee ground. A retention mechanism urges the door into the closed position and enables the door to open with an upward movement of the apparatus after the golf tee has been placed into the tee ground.
