Training Reco near Temecula (HS/ College aged)

We will be moving to Temecula soon (from out of state) and I wanted to ask if anyone had any recommendations on private and/ or group training options for U18 (07) player for this summer? My son will be attending a large public university in the fall that has a very competitive club team (and no NCAA team), so he wants to stay fresh with getting reps in before heading off to school (and college club tryouts) in August. Any guidance would be appreciated!
