Looking for 17-year-old males for my stepson to hang out with (menlo park)

I have a 17-year-old stepson who recently moved in with me and has commented that he would like some friends here in the area around his own age.
Does anyone have an educationally minded son who also would like a workout buddy at the gym? Planet fitness for example? Or practice basketball together? Please let me know if you have son around the same age it would be interested in doing the above with mine or who has a welcoming drug-free friends group (family and future oriented).
Thank you!
