Whatever became of Larry Matthews(Ritchie Petrie)?

After the DVD ended in '66, he finished his education & graduated from UCLA. He went into the production end of TV working for various shows. He now freelances as associte producer & assistant director.

Thanks for letting us know about Larry.I figured he went on to a different career.I did like him somewhat on DVD,but the older he got the less convincing his scenes were.
Many ex-child actors go on to other things and leave acting behind them.(Face it,too many of them were pushed into show-biz by parents and didn't really like being in front of the camera.)
