Personal trainer for 40 yr old, formerly very fit

I'm looking for personal trainer recommendations for my husband, who wants training sessions for Christmas. He's a 40 yr old formerly very fit and active skier/hiker/surfer who feels like he's getting old, doesn't have time to exercise since having a kid 4 years ago, and is perpetually sidelined by various injuries. He has a few extra pounds he'd like to take off, too. He needs someone who will lay out a path toward getting back into shape, and keep him accountable (he's more motivated to exercise if he's paying someone to help him). 

Any recommendations for trainers taking new clients in Berkeley/Albany/Oakland? Ideally they could work out either outdoors or in a well-ventilated, semi-private space, since we'll have a newborn at home this winter.
